[0002] CONNECTING ARRANGEMENT FOR CONNECTING STRUCTURAL COMPONENTS OF A SUPPORTING STRUCTURE
[0003] TECHNICAL FIELD
[0004] The present invention relates to a connecting arrangement for connecting structural parts according to claim 1, a supporting structure comprising structural parts which are connected to one another by means of the connecting arrangement according to claim 13, a method for connecting structural parts by means of the connecting arrangement according to claim 14, and a method for producing a corresponding connecting arrangement according to claim 15.
[0005] STATE OF THE ART
[0006] The design of buildings in zones with high earthquake risk presents a particular challenge, especially when the supporting structure is made of wood. With wood, the decisive loads are almost always those under which the material exhibits brittle failure. Therefore, skilled designers attach great importance to ensuring that the connection arrangement used to connect the structural components exhibits a forgiving deformation mode. Within a connection arrangement, the so-called ductility allows the acting forces to be distributed across as many components of the connection arrangement as possible. Testing a single component allows a statement to be made about local ductility. To assess the forgiving nature of an entire building, the global ductility (structural ductility) is considered. This yields the behavior coefficient q, which determines the effects of the earthquake action.The higher the behavior coefficient, the smaller the calculated forces in a stiffening load-bearing structure. To be able to apply a high behavior coefficient, the building must be extremely flexible and thus "destroy" (dissipate) the kinetic energy of the earthquake. The structural standards (SIA 265, SIA 263, or Eurocode 8) specify behavior coefficients for "common" construction methods. For timber construction, the behavior coefficient q according to SIA 265 is between 1.5 and 3.0. However, current research results point to serious challenges when a q of, for example, 3.0 is to be guaranteed in timber construction with common connection arrangements (ductile regions). Therefore, a conservative design based on non-ductile structural behavior (q = 1.5) is currently being advocated in teaching to account for brittle failure modes.
[0007] In principle, however, the supporting structures of buildings must also be very rigid so that they do not deform too much under the influence of wind.
[0008] In some situations, these serviceability criteria compete with the desired ductility for the seismic load case.
[0009] US 2017 / 268252 A discloses structurally flexible connecting elements for connecting building frame structures, in particular eccentrically braced frames. The ends of each connecting element are screwed to a surface of the frame structures, thereby creating a fixed connection.
[0010] For connecting wall elements, CN 206 941 865 U discloses several vertically stacked connecting elements, each of which is welded to strip elements at its end. Parallel side panels are attached to the outside of the wall elements to be connected. These side panels protrude from the end face of the wall elements in the connection direction. The strip elements are inserted between them and are firmly connected to the side panels via bolts.
[0011] A major disadvantage of these connecting elements is their fixed attachment at both ends, which can create a normal force in the connecting elements.
[0012] PRESENTATION OF THE INVENTION
[0013] It is an object of the present invention to provide a connection arrangement for connecting load-bearing parts of a supporting structure, which simultaneously provides high rigidity and high ductility and allows simple assembly. This object is achieved by a connection arrangement according to claim 1. That is, a connection arrangement for connecting load-bearing parts of a supporting structure is provided, wherein the connection arrangement comprises at least one connector element, at least one first connection part which can be attached to a first load-bearing part, and at least one second connection part which can be attached to a second load-bearing part to be connected to the first load-bearing part. The first connection part has at least one first recess for receiving a first end of the connector element. The second connection part has at least one second recess for receiving a second end of the connector element.The first and second ends of the connector element can be received in the first and second recesses, respectively, along an assembly direction. The assembly direction runs at an angle to a connection direction along which the first and second supporting structure parts can be connected to one another.
[0014] This means that the connecting arrangement according to the invention allows a connection of at least two supporting structure components of a supporting structure. The connector element of the connecting arrangement is mounted along an assembly direction that runs at an angle to the connection direction along which the supporting structure components are connected to one another. In other words, the assembly direction of the connector element does not run along, or rather, parallel to, the connection direction. In other words, an angle between the assembly direction and the connection direction is preferably not equal to 0°. Particularly preferably, the assembly direction runs perpendicular to the connection direction. In other words, the angle between the assembly direction and the connection direction is particularly preferably 90°.
[0015] Because the assembly direction does not run along or parallel to the connection direction of the structural components, any obstruction or blockage of the assembly by the structural components is avoided. The connection arrangement according to the invention thus enables the connector element to be assembled along a free assembly direction. In other words, the connector element can be assembled unhindered, since there is no obstruction by the structural components.
[0016] This free or unobstructed assembly is guaranteed for different arrangements of the structural components. For example, the two structural components to be connected can be arranged vertically, horizontally, or in any spatial orientation when the connecting arrangement is assembled. The assembled state corresponds to the state in which the two structural components of the supporting structure to be connected are connected to each other by means of the connecting arrangement.
[0017] In a vertical arrangement, the two structural members extend along a vertical direction, for example, vertically upwards as seen from a floor or other substructure. In a horizontal arrangement, the two structural members extend along a horizontal direction perpendicular to the vertical direction.
[0018] In the case of a vertical arrangement of the supporting structure components, the connector element of the connecting arrangement according to the invention is preferably mounted laterally. In other words, the connector element can be accommodated in the recesses along a mounting direction that runs within a horizontal plane. The aforementioned mounting direction runs within the horizontal plane.
[0019] In the case of a horizontal arrangement of the supporting structure components, the connector element of the connecting arrangement according to the invention is preferably mounted from above or below. In other words, the connector element is received in the recesses along a mounting direction that runs within a vertical plane. The vertical plane runs perpendicular to the horizontal plane, or the aforementioned mounting direction runs within the vertical plane.
[0020] Furthermore, the design and arrangement of the connecting assembly, when assembled, provides a shear force connection against any displacement of the connected structural components. The direction of this displacement or loading runs perpendicular to the connection direction and preferably perpendicular to the assembly direction.
[0021] The connector element is preferably formed in one piece. This means that the connector element is preferably a one-piece component.
[0022] The connector element preferably has a first and a second end region. These end regions can preferably be received in the recesses. In other words, the connector element can preferably be defined in at least three sections: the first section preferably lies within the first recess, the second section between the connection parts, and the third section within the second recess. Additionally or alternatively, the connector element is plastically deformable, preferably at least in the second section or, in the assembled state, in the areas directly next to the first and second recesses. The connector element particularly preferably comprises or consists of steel, in particular structural steel. Other plastically deformable materials, in particular plastically deformable metals, are, however, just as conceivable. The connector element is particularly preferably a one-piece or one-part piece made of steel orplastically deformable material. A plastic hinge can be formed in each of the first and second end regions of the connector element. This means that, in the assembled state and under correspondingly high force acting on the supporting structure, a plastic hinge preferably forms at both transitions to the second section, in the first and second end regions of the connector element.
[0023] Particularly preferably, the end regions of the connector element accommodated in the recesses of the connecting parts are designed and arranged in such a way that a joint forms when a yield stress is exceeded. In the event of a force, such as that resulting from wind loads, the connector element transmits this force, with only a (minor) elastic deformation occurring. In the event of an acceleration load, such as that resulting from earthquake loads, the connector element can limit the forces generated in the supporting structure by dissipating the acceleration energy through plastic deformation.
[0024] This means that the connector element preferably functions as a so-called seismic connector, in particular as a seismic connector according to Eurocode 8 (EN 1998-1:2004, Section 6.8). In other words, the connector element's function corresponds to that of a seismic connector, in particular the seismic connector according to Eurocode 8 (EN 1998-1:2004, Section 6.8).
[0025] This allows the connection arrangement to be very rigidly connected to the structural components, at least up to the wind load level, while remaining highly flexible should an earthquake exceed the design load level, while maintaining a high load-bearing capacity. In other words, the connection arrangement ensures ductility, which is desirable in terms of earthquakes, while still maintaining high stiffness, which is desirable in terms of wind. A further advantage of the connection arrangement is a low overstrength factor, since the load-bearing capacity of the connecting element can be guaranteed through testing and quality assurance.
[0026] The connector element preferably defines a longitudinal axis. In an assembled state of the connection arrangement, the longitudinal axis of the connector element preferably extends parallel to the connection direction. The assembly direction preferably runs at an angle and in particular perpendicular to the longitudinal axis of the connector element.
[0027] This means that the connector element is preferably an elongated element that defines a longitudinal axis. Furthermore, the connector element can have different shapes and, viewed in cross-section, can be, for example, rectangular or cylindrical, although other shapes are equally conceivable. In the assembled state of the connection arrangement, the connector element is preferably mounted in the recesses of the connecting parts such that its longitudinal axis extends parallel to the connection direction. Additionally or alternatively, it is preferred that the assembly direction, along which the connector element is received in the recesses, is inclined at an angle, in particular at right angles to the longitudinal axis of the connector element.
[0028] The first and second ends of the connector element, which can be received in the recesses of the connecting parts, are preferably free ends of the connector element. Particularly preferably, these are free ends of the connector element that are opposite one another with respect to the longitudinal axis of the connector element. For example, the connector element can be a rod with a rectangular cross-section, with the two rod ends providing the free ends.
[0029] The first and second ends of the connector element are preferably insertable into the first and second recesses. The connector element is preferably removable and / or replaceable and / or directly accessible to a designer and can be received in the first and second recesses.
[0030] The connector element is preferably inserted with its ends, particularly its two free ends, into the recesses of the connecting parts and thus received in the connecting parts. In the assembled state, the connector element is thus preferably supported with its ends in the recesses, particularly clamped therein for structural purposes.
[0031] The ends of the connector element thus preferably have a cross-sectional area that essentially corresponds to the clear width of the recesses. The recess has a minimal oversize of, for example, 2% (assembly clearance) relative to the connector element, which is required for assembly.
[0032] It is conceivable that the recesses are designed solely to accommodate the ends of the connector element. However, it is equally conceivable that the recesses each have at least one reinforcing element. The reinforcing element is preferably arranged and designed in such a way that it minimizes excessive stress, in particular deformation of the connecting part in the region of the recesses. The reinforcing element preferably has a particularly high level of hardness. Additionally or alternatively, the reinforcing element preferably enables a reaction to assembly tolerances of the supporting structure parts. The reinforcing element can be a reinforcing plate which is arranged within the recess. Particularly preferably, two reinforcing elements are provided per recess, and wherein one end of the connector element can be accommodated between these two reinforcing elements. Furthermore, it is conceivable that thethe reinforcing elements are arranged interchangeably in the recess. The reinforcing elements preferably each have a free side. The free side of the reinforcing elements is preferably a side facing away from the supporting structure part. Or in other words, the reinforcing elements preferably each comprise a rear side which faces the supporting structure parts, in particular their end face or side face. The free side of the reinforcing elements can be straight. This means that the free side of the reinforcing elements can run parallel to a connection direction or vertical direction running perpendicular to the connection direction. However, it is equally conceivable for the free side of the reinforcing elements to be curved. This means that the free side of the reinforcing elements preferably has a curvature starting from their free side in the direction of the rear side of the reinforcing elements.This curvature can also be referred to as a radius. The curvature or radius improves the cyclic ductility of the connection arrangement. As discussed below, a free side of the recesses can have a curvature or radius in addition to or alternatively to the free side of the reinforcing elements.
[0033] Especially in earthquake-resistant load-bearing structures, the weakest parts should be easily replaceable. Making the connecting element removable or replaceable makes it easier to rehabilitate a building after a strong earthquake.
[0034] The connector element is preferably removable by pulling it out of the recesses. Because the connector element can be inserted and removed from the recesses, it can be easily replaced.
[0035] The wearing parts in the event of a strong earthquake are therefore not only easily exchangeable and replaceable, but are also essentially limited to the connector element - the connection arrangement is therefore also characterized by few wearing parts or small wearing parts.
[0036] The first and second connecting parts can preferably each be attached to a surface, in particular to an end face or side face, of the first and second supporting structure parts, respectively. The surfaces are preferably opposite one another, viewed in the connection direction.
[0037] This means that the supporting structure components preferably each have a surface, for example, an end face or a side face. The connecting parts of the connecting arrangement can preferably be attached to these surfaces. These surfaces of the supporting structure components, and consequently also the connecting parts attached thereto, preferably lie opposite one another in the assembled state and with respect to the connection direction.
[0038] The connecting parts preferably comprise or consist of steel. The connecting parts are preferably strips or plates that are attached to the supporting structure parts. Particularly preferred are the connecting parts strips or plates made of steel, which, when installed, extend at least partially or completely along the surfaces, such as the end face or side face, of the supporting structure parts.
[0039] The first and second recesses in the first and second connecting parts, respectively, can be continuous or discontinuous with respect to the mounting direction. For example, if the connecting part is provided from two or more interconnected strips, the strips each have individual recesses, which, taken as a whole, can be viewed as a discontinuous recess. If the connecting part is formed from a single component, such as a plate, this can have a continuous or continuous recess.
[0040] As will be explained in more detail below, various supporting structures such as a wooden structure, a steel structure or a reinforced concrete structure are conceivable.
[0041] If the supporting structure is a wooden structure, the supporting structure components preferably comprise or consist of wood. In this case, it is preferred that the connecting parts are firmly attached to the surfaces, such as the end faces of the supporting structure components, for example by bonding using an adhesive. Furthermore, it is preferred that the supporting structure components have glued-in rods, such as threaded rods, profiled rods, or the like, which are connected, in particular screwed, to the connecting parts. The rods are preferably made of steel. A composite system is preferably formed from the wood of the supporting structure components, the adhesive, and the material of the rods, such as steel, which optimally attaches the connecting parts to the wooden supporting structure components.In particular, such a connection system allows the steel rods to fail (ductile) in a fracture state, while the brittle failure modes of the wood or the adhesive are excluded. This type of connection is well known in the field of invention and is referred to in timber construction, for example, as "glued-in rods" or "glued-in profiled rods."
[0042] If the supporting structure is a steel structure, the connecting parts are preferably connected to the supporting structure parts by soldering, welding or screwing.
[0043] If the supporting structure is a reinforced concrete structure, the connecting parts are preferably connected to the supporting structure parts by screwed reinforcement bars.
[0044] The first recess of the first connecting part preferably runs parallel to the second recess of the second connecting part. This means that in the assembled state, the recesses of the connecting parts preferably run parallel to one another. In an assembled state of the connecting arrangement, the first and second recesses preferably each run inclined, in particular at right angles, to the connection direction. The first and second recesses preferably run parallel to the mounting direction. The first and second connecting parts are preferably identical and / or arranged in a mirror image of one another with respect to a plane perpendicular to the connection direction in the assembled state.
[0045] This means that in the assembled state, the first and second recesses are preferably opposite each other with respect to the plane perpendicular to the connection direction.
[0046] The first and second recesses preferably extend at least partially, and particularly preferably completely, along the mounting direction. It is further preferred that the recesses extend at least partially or completely through a free side of the connecting parts.
[0047] The free side of the connecting parts is preferably a side facing away from the supporting structure part. In other words, the connecting parts preferably each comprise a rear side facing the supporting structure parts, in particular their end face or side face, and arranged opposite the free side containing the recess.
[0048] The recesses in the connecting parts are preferably milled, especially milled in the free sides of the connecting parts. It should be understood that the recesses can of course also be produced by other methods, such as thermal cutting, for example, by plasma or laser cutting, drilling, etching, etc.
[0049] The free side of the connecting parts can be straight. This means that the free side of the connecting parts can run parallel to the connection direction perpendicular to the connection direction or the vertical direction. If the connecting arrangement further comprises reinforcing elements comprising a curvature or radius that are accommodated in the recesses, it is preferred that the free side of the connecting parts be straight.
[0050] However, it is equally conceivable for the free side of the connecting parts to be curved, at least in the area of the recesses. This means that the free side of the connecting parts preferably has a curvature, viewed from the free side toward the rear of the connecting parts. This curvature can also be referred to as a radius. The curvature or radius of the free side of the connecting parts improves the cyclic ductility of the connection arrangement.
[0051] The connection arrangement preferably comprises at least one further connector element. The further connector element is preferably arranged offset from the first connector element with respect to the mounting direction and / or with respect to the connection direction running perpendicular to the connection direction.
[0052] This means that the connection arrangement can comprise two or more connector elements. All explanations regarding one connector element preferably also apply analogously to two or more connector elements, and vice versa.
[0053] If two or more connector elements are present, they are preferably arranged offset from one another with respect to the mounting direction and / or with respect to a connection direction running perpendicular to the connection direction. This connection direction preferably extends perpendicular to the longitudinal axis of the connector elements and / or parallel to a longitudinal axis of the connecting parts. Particularly preferably, the connection direction also runs perpendicular to the mounting direction.
[0054] Furthermore, it is preferred that the two or more connector elements are arranged parallel to each other.
[0055] A different number of connector elements can now be provided in different arrangements.
[0056] For example, the connection arrangement can comprise two connector elements, now called first and second connector elements. The first and second connector elements can be arranged consecutively along the assembly direction in the assembled state. Or in other words, the first and second connector elements can be arranged offset from one another with respect to the horizontal direction in the event that the structural components to be connected are aligned vertically. If the structural components are aligned horizontally, these two connector elements are arranged offset from one another with respect to the vertical direction. In both cases, the first and second connector elements can preferably each be received in the same (continuous or interrupted) recesses in the connecting components.In the assembled state, the first and second connector elements can also be arranged consecutively along the connection direction running perpendicular to the assembly direction. If the supporting structure parts are arranged vertically, this results in an offset arrangement for the first and second connector elements with respect to the vertical direction. Here, too, the first and second connector elements can be offset from one another with respect to the horizontal direction if the supporting structure parts are arranged horizontally. Furthermore, it is preferred that the first and second connector elements can each be accommodated in different recesses in the connection parts.
[0057] This means that, depending on the number and arrangement of the connector elements, the connecting parts preferably each have further recesses into which the first and second ends of the further connector elements can be received.
[0058] This means that the first connecting part can have at least one further first recess for receiving a first end of a further connector element and the second connecting part can have at least one further second recess for receiving a second end of the further connector element.
[0059] The first (second) and the further first (second) recess in the first (second) connecting part preferably run parallel to each other and / or offset from each other with respect to the connecting direction.
[0060] In addition to connector elements which, in the assembled state, are arranged consecutively along the assembly direction or along the connection direction, it is of course also possible to provide connector elements which, in the assembled state, are arranged consecutively both along the assembly direction and along the connection direction. For example, four connector elements can be provided, with a first and second connector element being arranged consecutively along the assembly direction and a third and fourth connector element being arranged consecutively along the assembly direction. However, with respect to the first and second connector element, the third and fourth connector elements are arranged offset along the connection direction. In this case, too, it is preferred that the first and second or the third and fourth connector elements are each arranged parallel to one another.
[0061] The number of connector elements and, as previously mentioned, the width of the connector elements allow the load-bearing capacity of the supporting structure formed from the supporting structure components to be precisely adjusted. Two or more connector elements arranged consecutively with respect to the assembly direction are preferably connected to one another via at least one connecting element. For example, the connecting element can be a bolt or a threaded rod that connects the successive connector elements to one another. In the assembled state, the connecting element thus preferably also extends along the assembly direction.
[0062] In particular, the connecting element can extend through the successive connector elements in the region of the first or second end of the connector elements.
[0063] Particularly preferably, two connecting elements are provided for each connector element which is arranged successively with respect to the mounting direction, wherein a first connecting element extends in the region of the first ends through the successive connector elements and a second connecting element extends in the region of the second ends through the successive connector elements.
[0064] The provision of the connecting elements allows for easier assembly in the case of these several consecutive connector elements, since these connector elements can thereby be inserted into the recesses as a unit.
[0065] At least one first pressure element can be arranged on the first connecting part, and at least one second pressure element can be arranged on the second connecting part. The first and second pressure elements are preferably designed to transmit pressure forces along the connection direction. This can prevent crushing of the connector element. The first and second pressure elements can each have a contact surface for forming a surface contact in the assembled state of the connection arrangement.
[0066] This means that the pressure elements preferably each have a contact surface and are arranged on the connecting parts in such a way that, when the connecting arrangement is assembled, they abut against each other and can form a surface contact. In particular, the surface contact occurs via the two contact surfaces, which press against each other when a high pressure force is applied along the connection direction.
[0067] The first pressure element preferably extends away from the first connection part along the connection direction from the first connection part and the second pressure element preferably extends away from the second connection part along a direction opposite to the connection direction from the second connection part.
[0068] The pressure elements are preferably each mounted on the free surface of the connecting parts, for example, screwed or welded thereto. This means that the pressure elements and the connecting parts are preferably separate components. However, it is also conceivable for the pressure elements and the connecting parts to be formed integrally, i.e., for the pressure elements to be designed as projections or the like that protrude from the connecting parts on the free side.
[0069] The pressure elements are preferably made of steel, although other materials are also conceivable.
[0070] The contact surfaces of the first and second pressure elements preferably each have a friction guard to minimize or prevent static and / or sliding friction forces. In this case, it is preferred that the surface contact between the two contact surfaces occurs via the friction guard. In other words, the friction guard is arranged between the two contact surfaces when the pressure elements press against each other. The friction guard is preferably a Teflon film.
[0071] The contact surfaces of the first and second pressure elements preferably each have one or more recesses running in the connection direction. In this case, it is preferred that a fastening element is mounted therein in order to minimize or prevent displacement under low loads (slippage) due to the assembly play of the connector elements. In particular, the fastening element is received in the recess(es) of the pressure elements and fastens the contact surfaces of the pressure elements to one another. The fastening element particularly preferably has a machining which significantly influences its tensile load-bearing capacity. In particular, the fastening element is elastically and / or plastically extensible. Accordingly, the fastening element is particularly preferably an expansion screw. These fastening elements improve the rigidity of the connection arrangement in the elastic range.They fail as planned at a stress level which, according to the design, only occurs in the event of an earthquake.
[0072] The fastening element can be mechanically attached to the pressure elements, for example, via a screw connection and / or dowel pins. For example, the fastening element can be an expansion screw comprising a screw head or nut at both ends, with a washer preferably arranged between the screw head or nut and the pressure elements. Its position is particularly preferably secured with a dowel pin extending into the pressure element.
[0073] The connecting arrangement preferably comprises at least one securing element for securing the position of the connector element received in the first and second recesses. The securing element is preferably connectable, in particular screwable, to the connector element and / or the first connecting part and / or the second connecting part.
[0074] The securing element is preferably connected to the first and / or second connection part after the connector element has been received in the recesses of the connection parts. In particular, it is preferred to connect the securing element to the first and / or second pressure element of the first or second connection part. For example, the securing element can be a tab plate that is screwed to the first or second pressure element. Additionally or alternatively, the connector element can also be connected to the securing element, for example, by screwing the tab plate to the connector element.
[0075] The securing element is preferably attached to the first side of the first connecting parts, as seen in the assembly direction, and to the last side, preferably perpendicular to the assembly direction. These securing elements can be attached to the first or second structural part prior to its assembly. If necessary, the securing elements can also be attached at the end or at any time in between.
[0076] It is particularly preferred that the connector element be secured at only one end, i.e., that one or preferably two securing elements are provided in the region of the first end of the connector element or in the region of the second end of the connector element. The aim of this securing at only one end is to prevent any planned forces (normal forces) from occurring in the connector element in the direction of its longitudinal axis.
[0077] However, other designs are equally conceivable. Freedom of movement along its longitudinal axis could, for example, be ensured by elongated holes in the screw connection of the locking element to one of the two connecting parts. This allows the locking elements to be attached to both sides of the connector element and / or the locking elements to be welded to the connector element, etc.
[0078] The connecting arrangement preferably comprises at least one tension element for transmitting tensile forces along the connecting direction. The tension element is preferably receivable in a first and second recess of the first and second supporting structure parts and is preferably a secondary component and / or an elongated element such as a threaded rod.
[0079] This means that the tension element is preferably a separate component anchored in both structural parts to be connected, e.g. a secondary component such as a ceiling element or another preferably elongated element such as a threaded rod.
[0080] If the tension element is formed by an elongated element, it is preferably arranged in a corresponding recess in the first and second supporting structure parts to be connected. The recesses preferably extend along the connection direction.
[0081] The recesses can be millings, holes, etc.
[0082] In a further aspect, a supporting structure comprising at least a first supporting structure part, a second supporting structure part, and a connecting arrangement as described above is provided. The connecting arrangement connects the first supporting structure part and the second supporting structure part to one another along the connecting direction.
[0083] All explanations regarding the connection arrangement per se preferably apply analogously to the supporting structure, including the connection arrangement, and vice versa. The supporting structure components are preferably bars, beams, struts, columns, etc. as are generally known to those skilled in the art. In particular, the supporting structure is preferably a wooden structure, a steel structure, or a reinforced concrete structure. If the supporting structure is a wooden structure, the supporting structure components to be connected preferably comprise or consist of wood. If the supporting structure is a steel structure, the supporting structure components to be connected preferably comprise or consist of steel. If the supporting structure is a reinforced concrete structure, the supporting structure components to be connected preferably comprise or consist of concrete with steel reinforcement.This means that the first and second structural components are preferably a timber component, a steel component or a reinforced concrete component.
[0084] Furthermore, it is preferred that the supporting structure components are connected to form a frame and / or truss construction. A supporting structure according to the invention is also conceivable, the supporting structure components being formed by at least two walls. Such walls can be, for example, solid panels made of cross-laminated timber or, for example, timber frame walls with stiffening planking. Likewise, at least two columns made of wood, steel, or other materials can form the supporting structure components of a supporting structure according to the invention, referred to as a "linked column frame." However, the supporting structure components particularly preferably form a so-called "eccentrically braced frame," abbreviated to "EBF." This means that the present invention offers structural solutions for the design of a seismic connector in an EBF made of steel and, in particular, also of wood.In particular, the supporting structure according to the invention enables timber construction to achieve behavioral coefficients q that were previously only applicable to steel construction.
[0085] In another aspect, a method for connecting structural members of a supporting structure is provided. The method comprises the steps of:
[0086] - Providing at least a first structural part and a second structural part;
[0087] - Providing at least one connecting arrangement as described above; and
[0088] - Connecting the first and second supporting structure parts along the connecting direction, wherein the first and second ends of the connector element are received along the mounting direction in the first and second recesses of the first and second connecting parts, respectively.
[0089] All explanations regarding the connection arrangement per se and the supporting structure comprising such a connection arrangement preferably apply analogously to the method for connecting structural components with such a connection arrangement and vice versa.
[0090] The connection arrangement preferably does not restrict the order or the assembly direction of the structural components.
[0091] In a further aspect, a method for producing a connecting arrangement for connecting supporting structure parts of a supporting structure, in particular a connecting arrangement as described above, is provided. The method comprises the steps of:
[0092] - Providing at least one connector element;
[0093] - Providing at least one first connecting part which can be attached to a first supporting structure part; and
[0094] - Providing at least one second connecting part which can be attached to a second supporting structure part to be connected to the first supporting structure part.
[0095] The first connecting part has at least one first recess for receiving a first end of the connector element. The second connecting part has at least one second recess for receiving a second end of the connector element.
[0096] The first end and the second end of the connector element can be received in the first and second recesses, respectively, along an assembly direction. The assembly direction runs at an angle to a connection direction along which the first and second supporting structure parts can be connected to one another.
[0097] All explanations regarding the connection arrangement per se, the supporting structure comprising such a connection arrangement and the method for connecting the supporting structure parts with such a connection arrangement preferably apply analogously to the method for producing such a connection arrangement and vice versa.
[0098] The strength of the connector element material is determined prior to its manufacture, preferably through at least one representative test. Based on these results, the cross-sectional geometry of the connector element can be determined, and thus the load-bearing capacity—that is, the shear force at which the connector element begins to yield—can be adapted to the requirements of the current problem (ensuring ductile load-bearing behavior, stability, stiffness, etc.). The problem here is understood to be the design of the specific structure with all its project-specific boundary conditions.

[0136] DESCRIPTION OF PREFERRED EMBODIMENTS
[0137] Aspects of the connecting arrangement 1 according to the invention will now be explained in conjunction with the figures. It should be understood that certain components have been omitted for the sake of clarity. This applies in particular to Figure 8 and Figures 11 to 22.
[0138] The figures each show a connecting arrangement 1 for connecting supporting structure parts 4, 6 of a supporting structure 25. As can be seen in particular from Figures 1, 2 and 8, the connecting arrangement 1 has at least one connector element 2, at least one first connection part 3 and at least one second connection part 5. The first connection part 3 can be attached to a first supporting structure part 4 and the second connection part 5 can be attached to a second supporting structure part 6 to be connected to the first supporting structure part 4. The first connection part 3 has at least one first recess 7 for receiving a first end 8 of the connector element 2 and the second connection part 5 has at least one second recess 9 for receiving a second end 10 of the connector element 2, see Figure 8.As can further be seen from Figure 8, the first and second ends 8, 10 of the connector element 2 can be received into the first and second recesses 7, 9, respectively, along a mounting direction M, wherein the mounting direction M runs at an angle to a connecting direction R, along which the first and second supporting structure parts 4, 6 can be connected to one another. This means that the connector element 2 is mounted along a mounting direction M which runs at an angle to the connecting direction R, and thereby forms an angle ß between the mounting direction M and the connecting direction R of a direction other than 0°. In the figures shown here, the angle ß is 90° in each case.
[0139] As can be clearly seen from Figures 1 to 3, the connecting parts 3, 5 are each attached to a surface 23, 24, here each to an end face, of the supporting structure parts 4, 6, wherein these end faces are opposite one another with respect to the connection direction R. If the supporting structure 25 is a wooden structure, the connecting parts 3, 5 can be attached to the end faces of the supporting structure parts 4, 6 by means of glued-in rods. Furthermore, the supporting structure parts 4, 6 comprise glued-in rods 26, such as threaded rods, which are additionally connected to the connecting parts 3, 5, see, for example, Figure 2.
[0140] As can be seen in particular from Figures 6a to 7b, the recesses 7, 9 are located opposite one another and run parallel to one another and preferably at right angles to the connection direction R. In addition, the recesses 7, 9 preferably extend completely through a free side 27, 28 of the connecting parts 3, 5.
[0141] The connector element 2 is an elongated element that defines a longitudinal axis L (see Figures 2 and 6a to 7b). In the embodiment shown, the connector element 2 is a rectangular element that is formed in one piece and made of steel. In the assembled state of the connection arrangement 1, the connector element 2 is mounted in the recesses 7, 9 of the connecting parts 3, 5 such that its longitudinal axis L extends parallel to the connection direction R. The assembly direction M, along which the connector element 2 is received in the recesses 7, 9, runs at a right angle a to the longitudinal axis L of the connector element 2 (see Figures 1 and 2).
[0142] As can be seen from Figures 6a to 7b, the first and second ends 8, 10 of the connector element 2, which can be received in the recesses 7, 9 of the connecting parts 3, 5, are preferably free ends of the connector element 2. Particularly preferably, they are free ends 8, 10 of the connector element 2 that are opposite one another with respect to the longitudinal axis L of the connector element 2. For example, the connector element 2 can be a rod with a rectangular cross-section, wherein the two rod ends provide the free ends 8, 10. The connector element 2 is inserted with its two free ends 8, 10 into the recesses 7, 9 of the connecting parts 3, 5 and is thereby received in the connecting parts 3, 5.
[0143] The connecting assemblies 1 of Figures 6a to 7b differ in that the connecting assembly 1 according to Figures 7a and 7b further comprises reinforcing elements 29 in the form of reinforcing plates, which are arranged within the recesses 7, 9. The ends 8, 10 of the connector element 2 of the connecting assembly 1 according to Figures 6a and 6b preferably have a cross-sectional area that essentially corresponds to the inside width of the recesses 7, 9. The recesses 7, 9 according to Figures 7a and 7b are somewhat larger to accommodate the reinforcing elements 29. In both cases, the connector element 2 has a first end region 21 and a second end region 22. In the assembled state and under correspondingly large force acting on the supporting structure, a plastic joint 30 is preferably formed near the recesses 7, 9 in the first and second end regions 21, 22 of the connector element 2.In addition, the connector element 2 is plastically deformable, at least in the end regions 21, 22, i.e., in the assembled state, in the regions directly adjacent to the first and second recesses 7, 9. As can be seen in particular from a comparison of Figures 4b and 5b, the end regions 21, 22 of the connector element 2 accommodated in the recesses 7, 9 of the connecting parts 3, 5 are designed and arranged such that, when a yield stress is exceeded, a plastic joint 30 forms at both transitions to the second section 33.
[0144] The connecting arrangement 1 in Figure 6b corresponds to that in Figure 6a, with the difference that the free sides 27, 28 of the connecting parts 3, 4 of the connecting arrangement 1 in Figure 6a are straight and run parallel to the connecting direction A or vertical direction V. The connecting arrangement 1 according to Figure 6b, on the other hand, has connecting parts 3, 4 with free sides 27, 28 that are curved in the region of the recesses 9, 9a and, starting from the free side 27, 28 in the direction of the rear side 41, 42 of the connecting parts 3, 4, each have a curvature 38 or radius, respectively. Or in other words, curved free sides 27, 28 open into the recesses 9, 9a.
[0145] The same applies to Figures 7a and 7b. That is, the connection arrangement 1 in Figure 7b corresponds to that in Figure 7a with the difference that the free sides 39 of the reinforcing elements 29 in Figure 7a are straight and run parallel to the connection direction A or vertical direction V. In the embodiment of Figure 7b, however, the free sides 39 of the reinforcing elements 29 are curved and, starting from their free side 39, each have a curvature 43 or radius as viewed towards the rear side 40 of the reinforcing elements 29. The connection arrangements 1 shown in Figures 6b and 7b with curvature 38, 43 or radius on the free sides improve the cyclic ductility of the connection arrangement.
[0146] As can be seen from the figures, the connection assemblies 1 can have a different number of connector elements 2, 2a, .... For example, the connection assemblies 1 of figures 8 to 10 each comprise one connector element 2, while the connection assemblies 1 of the remaining figures each comprise two or more connector elements 2, 2a, .... Aspects of a connection assembly 1 comprising two or more connector elements 2, 2a, ... will now be explained with reference to figure 11. This means, and as can be seen from figure 11, the connection assembly 1 can comprise two or more, in the case shown six, connector elements 2, 2a, .... These connector elements 2, 2a, ... are arranged parallel to one another. Furthermore, some of these connector elements are arranged offset from one another with respect to the mounting direction M and with respect to a connection direction A running perpendicular to the connection direction R.This connection direction A extends here perpendicular to the longitudinal axis L of the connector elements and parallel to a longitudinal axis LA of the connecting parts and also perpendicular to the mounting direction M. Namely, three connector elements are arranged one after the other in the mounted state along the mounting direction M. These three connector elements are each accommodated in the same recesses 7, 9 of the connecting parts 3, 5. Three further connector elements are also arranged one after the other in the mounted state along the connection direction A running perpendicular to the mounting direction M. These three further connector elements are accommodated in further recesses 7a, 9a of the connecting parts 3, 5.This means that the first connecting part 3 has a further first recess 7a for receiving the first ends 8a of the further connector elements 2a, and the second connecting part 5 has a further second recess 9a for receiving the second ends 10a of the further connector elements 2a. Two or more connector elements, which are arranged consecutively with respect to the mounting direction M, are connected to one another here via two connecting elements 31 in the form of bolts.
[0147] As can be seen in particular from Figures 2, 6a and 6b, pressure elements 11, 12 can be arranged on the first connecting part 3 or on the second connecting part 5. These pressure elements 11, 12 serve to transmit compressive forces along the connection direction R. Furthermore, the pressure elements 11, 12 can each have a contact surface 13, 14 for forming a surface contact in the assembled state of the connecting arrangement 1, see Figure 2. In addition, the contact surfaces 13, 14 each have a friction protection 15, 16 in the form of a Teflon film to minimize or prevent static and / or sliding friction forces.
[0148] As further shown in Figures 1 and 2, the connecting arrangement 1 can comprise one or more securing elements 17 for securing the position of the connector elements 2 accommodated in the recesses 7, 9. In the example shown here, the securing element 17 is a tab plate, which is screwed to the pressure elements 11, 12. This tab plate simultaneously ensures the bearing security against lateral displacement of the supporting structure components, i.e., displacement perpendicular to the plane spanned by the connection direction and the connection direction.
[0149] As can also be seen from Figures 1 to 5b, a tension element 18 can be provided for transmitting tensile forces along the connecting direction R. The tension element 18 is received here in a first and second recess 19, 20 of the first and second supporting structure parts 4, 6 and is a threaded rod, see Figure 2.
[0150] As can be seen particularly from Figures 8 to 22, the connecting arrangement 1 can be used to connect a wide variety of structural components 4, 6 as well as in a wide variety of supporting structures 25. Parts of the connecting arrangement have not been shown in Figures 8 to 22 in order to keep the connector elements visible.
[0151] For example, the supporting structure parts 4, 6 can be wooden components or steel components such as bars, beams, struts, and supports made of wood or steel. Furthermore, the supporting structure parts 4, 6 to be connected can be arranged horizontally or vertically in the assembled state. In the vertical arrangement, the two supporting structure parts 4, 6 extend along a vertical direction V, for example, vertically upwards as seen from a floor or other subsurface. In the horizontal arrangement, the two supporting structure parts 4, 6 extend along a horizontal direction H running perpendicular to the vertical direction V. In the case of the vertical arrangement of the supporting structure parts 4, 6, the connector element 2 of the connection arrangement 1 according to the invention is preferably mounted laterally. Or in other words, the connector element 2 can be received in the recesses 7, 9 along a mounting direction M, which runs within a horizontal plane.The aforementioned horizontal direction H runs within the horizontal plane. In the case of the horizontal arrangement of the load-bearing structural components 4, 6, the connector element 2 of the connection arrangement 1 according to the invention is preferably mounted from above or from below. Or in other words, the connector element 2 is received in the recesses 7, 9 along an assembly direction M, which runs within a vertical plane. The vertical plane runs perpendicular to the horizontal plane, or the aforementioned vertical direction V runs within the vertical plane. As can also be seen from Figure 21, the connection arrangement 1 is also used in solid construction, wherein, for example, two load-bearing structural components 4, 6 in the form of (prefabricated) concrete elements or wall panels made of cross-laminated timber (CLT) are connected to one another.As Figure 22 shows, applications of the connecting arrangement 1 according to the invention between supporting structure parts 4, 6 in the form of wooden elements in frame construction are also possible.
[0152] As can be seen particularly from Figures 23 and 24, the connection arrangement 1 can be positioned in a wide variety of supporting structures 25. For example, the supporting structures can form cantilevered plates, so-called cantilevers, or act as girders over multiple supports, see Figure 24c. The arrows in these figures represent actions on the supporting structure and its support reactions.
[0153] Figures 25a and 25b show pressure elements 11, 12 with recesses 34, 34a, in each of which a fastening element 35 extends to minimize slippage. This means that the contact surfaces 13, 14 of the pressure elements 11, 12 each have a recess 34, 34a extending in the connection direction A, in which a fastening element 35, here in the form of an expansion screw, is mounted. Also visible are washers 36 with pins 37 extending into the pressure elements 11, 12 to secure their position. LIST OF REFERENCE SYMBOLS
