Description

Technical Field

[0001] The invention belongs to the field of structural shock absorption and vibration control of construction engineering technology, and specifically relates to a column-embedded thick-mesh rubber vertical seismic isolation and vibration control node suitable for a steel frame structure. Background Art

[0002] Earthquakes are a natural disaster that poses a serious threat to the safety of life and property of the people. They are difficult to predict and highly destructive. During an earthquake, buildings are subjected to repeated horizontal and vertical dynamic forces, which cause vibrations and even damage to the building structure, non-structural components, and devices and equipment in the building, resulting in casualties and property losses. In addition, environmental excitation caused by modern urban construction often causes excessive vibration responses in building structures. Although this type of environmental excitation response generally does not cause structural safety problems, it may threaten the normal use of the structure and affect the comfort of personnel.

[0003] In order to reduce the damage caused by earthquake motion or to reduce the excessive environmental excitation response, many engineering technical methods have emerged, among which seismic isolation technology is one of the most effective methods. Among the various seismic isolation methods, the most commonly used method is horizontal seismic isolation, which can effectively reduce the response of seismic isolation structures under horizontal earthquake motion / environmental excitation. However, this widely used seismic isolation method mostly does not consider the vertical seismic / vibration response of the structure during the design process. Studies have shown that non-structural components (such as suspended ceilings, fire sprinkler pipe systems, etc.) are easily damaged and fail due to vertical earthquake motion in horizontally isolated buildings, and important equipment installed in some buildings (such as medical equipment, etc.) is also difficult to withstand severe vertical vibration. In addition, the vertical vibration response of large-span structures is the main cause of their comfort problems. Therefore, from the perspective of ensuring the sustainability of building functions and the safety of people in buildings, it is necessary to take measures to reduce the adverse effects of vertical seismic action / environmental excitation.

[0004] The three-dimensional seismic isolation system developed in recent years combines horizontal seismic isolation with vertical seismic isolation devices, trying to reduce the response of the structure under horizontal and vertical earthquake / environmental excitation at the same time. But so far, the research on the three-dimensional seismic isolation system has focused on how to increase the horizontal and vertical flexibility at the bottom of the building structure at the same time, so as to reduce the three-dimensional seismic / environmental excitation response of the structure. For building structures that adopt base three-dimensional seismic isolation, it is necessary to coordinate the irreconcilable contradiction of "high vertical stiffness under gravity" and "high vertical flexibility under earthquake / environmental excitation" in the base isolation layer. Therefore, the structure of its vertical seismic isolation device is often very complicated, and its vertical seismic isolation effect is relatively limited.

[0005] In order to overcome the difficulty of centrally setting vertical isolation devices at the bottom of the structure and realize multi-level, controllable and effective vertical isolation, some scholars have proposed a "distributed vertical isolation and vibration control" system, which is to introduce vertical flexible nodes with horizontal constraints in the structural columns of one or more floors to increase the vertical flexibility and damping of the upper structure without affecting the lateral resistance of the structure. Studies have shown that compared with traditional base isolation frames, the use of the "distributed vertical isolation and vibration control" system can significantly reduce the vertical acceleration response of the structure, reduce the possibility of damage to non-structural components such as suspended ceilings, and improve personnel comfort.

[0006] The realization of the "distributed vertical seismic isolation and vibration control system" requires the introduction of a brand new column node that has not yet been proposed. Its function is to reduce the axial stiffness of the column and provide axial additional damping, while transmitting the shear force inside the column. Specifically, the node is set in the middle of the column section (the position of the inflection point inside the column under horizontal load). The corresponding bending moment in the column is very small, and the structure has extremely low requirements for the moment transmission capacity of this node. Therefore, the node only needs to transmit the shear force inside the column while providing vertical flexibility and additional damping. In view of this, a new type of "shear-resistant but not bending-resistant" vertical seismic isolation and vibration control node has become an actual demand in the current construction engineering field.

In the "distributed vertical isolation and vibration control" system, the probability of the ceiling exceeding the minor damage state was reduced to between 40% and 60%.

[0026] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0027] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0028] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor is it a separate or selective embodiment that is mutually exclusive with other embodiments.

[0029] The technical solution of the present invention is further described below in conjunction with the embodiments and drawings. It should be particularly noted that the key technology of the present invention is how to reduce the axial stiffness of the column and provide additional axial damping while transmitting the shear force in the column. Any changes to the cross-sectional shape of the column, the cross-sectional shape of the seismic isolation assembly, the shape of the tie hoop plate, the shape and number of the shear ribs should be within the scope of protection of the present invention.

[0030] Example 1

[0031] Reference Figure 1 and Figure 2, which is the first embodiment of the present invention, and this embodiment provides a thick-meat rubber vertical seismic isolation and vibration control node embedded in a steel frame structure column. The thick-meat rubber vertical seismic isolation and vibration control node embedded in a steel frame structure column includes a column 100, an isolation assembly 200, and a constraint assembly 300. The column 100 is the vertical main part of the steel frame structure. The isolation assembly 200 amplifies the axial flexibility of the column and provides axial additional damping for the column 100 to reduce the vertical seismic response or vertical environmental excitation response of the structure. The constraint assembly 300 is used to transmit the horizontal shear force in the column and constrain the movement direction of the column 100.

[0032] Specifically, the column 100 is vertically arranged, and includes a lower column 101 and an upper column 102. One end of the lower column 101 is connected to a fixed point, and the upper column 102 is arranged at an end of the lower column 101 away from the fixed point. The upper column 102 and the lower column 101 are on the same straight line.

[0033] The lower column 101 provides support for the upper column 102. The connection between the lower column 101 and the upper column 102 is the middle section of the column (the position of the inflection point inside the column under horizontal load), which reduces the requirements of the structure on the node moment transfer capacity and does not affect the horizontal stiffness and bearing capacity of the structure when the node is "shear-resistant but not bending-resistant".

[0034] The seismic isolation assembly 200 is arranged between the lower column 101 and the upper column 102, and includes a seismic isolation member 201 and a clamping member 202. The seismic isolation member 201 is arranged between the clamping members 202. One side of the clamping member 202 is connected to the upper column 102, and the side away from the upper column 102 is connected to the lower column 101.

[0035] The seismic isolation member 201 is used to transmit vertical axial force, amplify the axial flexibility of the column, and provide additional axial damping for the column 100 to reduce the vertical seismic response of the structure or the vertical environmental excitation response. The clamp 202 is used to fix the position of the seismic isolation member 201 and connect the seismic isolation assembly 200 to the column 100.

[0036] The restraint assembly 300 is disposed at the connection between the lower column 101 and the upper column 102 , and is used to transmit horizontal shear force and restrain the range of movement of the upper column 102 .

[0037] Example 2

[0038] Reference Figures 2 to 4 , which is the second embodiment of the present invention, and this embodiment is based on the previous embodiment.

[0039] Specifically, the lower column 101 is provided with a lower column end plate 101a, and the lower column end plate 101a is arranged at one end of the lower column 101 close to the upper column 102;

[0040] The lower column end plate 101 a is used to connect with the clamping member 202 to stabilize and fix the position of the seismic isolation assembly 200 .

[0041] Specifically, the upper column 102 is provided with an upper column end plate 102a, and the upper column end plate 102a is arranged at one end of the upper column 102 close to the lower column 101;

[0042] The upper column end plate 102 a is used to connect with the clamping member 202 to ensure that the upper column 102 can be stably installed on the seismic isolation assembly 200 .

[0043] Furthermore, the seismic isolation member 201 includes a rubber layer 201a and a steel gasket 201b, the rubber layer 201a is provided with at least two layers, and the steel gasket 201b is provided between every two adjacent rubber layers 201a;

[0044] The rubber layer 201a needs to be thick rubber with a small shape coefficient (i.e., the ratio of the constraint area to the free surface area is small) to provide sufficient vertical flexibility and additional damping to achieve the expected function of the node. The steel gasket 201b increases the vertical stiffness of the seismic isolation member 201 to withstand the vertical load. It is worth noting that the seismic isolation member 201 may also include only a single rubber layer 201a. The number of rubber layers 201a is determined according to the actual required seismic isolation effect. The seismic isolation member 201 in this embodiment has three rubber layers 201a.

[0045] Furthermore, the clamping member 202 includes a top plate 202a and a bottom plate 202b, wherein the top plate is disposed above the seismic isolation member 201 and is in contact with the upper column end plate 102a, and the bottom plate 202b is disposed below the seismic isolation member 201 and is in contact with the lower column end plate 101a;

[0046] The top plate 202a is used to be fixed to the upper column end plate 102a, and the bottom plate 202b is used to be fixed to the lower column end plate 101a.

[0047] Furthermore, the clamping member 202 is also provided with a first high-strength bolt 202c, which is provided on the top plate 202a and the bottom plate 202b. The first high-strength bolt 202c on the top plate 202a is connected to the upper column end plate 102a, and the first high-strength bolt 202c on the bottom plate 202b is connected to the lower column end plate 101a.

[0048] The first high-strength bolt 202c is used to fix the column 100 and the seismic isolation assembly 200 to make them tightly connected.

[0049] Example 3

[0050] Reference Figures 2 to 4 , which is the third embodiment of the present invention, and is based on the first two embodiments.

[0051] Specifically, the lower column 101 is further provided with a stiffening rib 101b, which is distributed around the lower column 101, one end of the stiffening rib 101b is connected to the side of the lower column 101, and the end away from the lower column 101 is connected to the lower column end plate 101a;

[0052] The stiffening rib 101b can enhance the local stiffness of the lower column.

[0053] Specifically, the restraint assembly 300 includes a shear rib 301 and a tie hoop plate 302. The shear rib 301 is distributed around the seismic isolation assembly 200. One end of the shear rib 301 is in contact with the lower column end plate 101a, and the end away from the lower column end plate 101a is connected to the tie hoop plate 302. The side of the tie hoop plate 302 away from the shear rib 301 is in contact with the side of the upper column 102, and the two ends of the tie hoop plate 302 are respectively in contact with the tie hoop plates 302 adjacent to them.

[0054] The shear rib 301 increases the shear resistance of the column 100, and realizes the transmission of horizontal shear force between the upper column 102 and the lower column 101. The hoop plate 302 is used to constrain the horizontal displacement of the upper column 102, ensuring that the upper column 102 and the lower column 101 are always in the same straight line. The hoop plate 302, the shear rib 301 and the lower column end plate 101a jointly transmit the horizontal shear force.

[0055] Furthermore, the restraint assembly 300 further includes a second high-strength bolt 303, the second high-strength bolt 303 connects the shear rib 301 and the lower column end plate 101a, and the second high-strength bolt 303 also connects two adjacent tie hoop plates 302;

[0056] The pre-tightening force of the second high-strength bolt 303 makes the inner periphery of the tie hoop plate 302 press against the side of the upper column 102, thereby realizing the "hoop" constraint on the upper column 102. The second high-strength bolt 303 also stably connects the shear rib 301 and the lower column end plate 101a.

[0057] Specifically, a thin layer of lubricating oil 302a is provided at the joint between the tie hoop plate 302 and the upper column 102;

[0058] The thin layer of lubricating oil 302a reduces the friction between the upper column 102 and the tie hoop plate 302, so that the "hoop effect" of the tie hoop plate 302 only constrains the horizontal displacement of the upper column 102, and does not constrain its vertical displacement.

[0059] When in use, the embedded thick-mesh rubber vertical seismic isolation and vibration control node of the steel frame structure column is set on any floor, and the seismic isolation component 200 embedded in the column 100 is used to amplify the axial flexibility of the column, transmit the vertical axial force, and provide axial additional damping for the column 100 to reduce the vertical seismic response of the structure or the vertical environmental excitation response; the hoop plate 302, the shear rib 301 and the lower column end plate 101a are used between the upper column 102 and the lower column 101 to transmit the horizontal shear force in the column, and the hoop plate 302 is used to realize the encirclement constraint of the upper column 102 by high-strength bolts to ensure the stability between the upper column 102 and the lower column 101 The node is set in the middle of the column (the inflection point in the column under horizontal load). Since the corresponding bending moment in the column is very small, the structure has extremely low requirements on the moment transfer capacity of the node. Therefore, the node only needs to transfer the shear force in the column while providing vertical flexibility and additional damping to reduce the structure's requirements on the moment transfer capacity of the node. Therefore, when the node is "shear-resistant but not bending-resistant", the horizontal stiffness and bearing capacity of the structure are not affected, and finally the "distributed vertical seismic isolation and vibration control" system is realized, achieving distributed multi-level flexible vertical seismic isolation and vibration control, and greatly reducing the vertical seismic response or vertical environmental excitation response of the structure.

[0060] In order to verify and illustrate the technical effects used in this method, this embodiment chooses to add a formula estimation process to compare the effects of the prior art by means of scientific demonstration to verify the real effect of this method:

[0061] Research shows that the vertical equivalent damping ratio of laminated rubber bearings produced in accordance with national and industry standards is approximately 0.025 to 0.065. Since thick rubber will have superior damping energy dissipation performance compared to standard laminated rubber bearings, and the vertical equivalent damping ratio of the steel frame structure can be considered to be smaller than the horizontal equivalent damping ratio (about 0.02), the vertical equivalent damping ratio of the traditional steel frame can be taken as 0.01, and the vertical equivalent damping ratio of the steel frame using the "distributed vertical seismic isolation and vibration control" system is 0.06. According to the "Code for Seismic Design of Buildings GB50011-2010", the earthquake force can be calculated as follows:

[0062] F Evk =α vmax G eq

[0063] F Evk ——Standard value of vertical earthquake action on structure

[0064] α vmax ——Maximum value of vertical earthquake influence coefficient

[0065] G eq ——Equivalent total gravity load of the structure

[0066] According to my country's seismic design response spectrum, when the natural vibration period of the structure is within the range of 0.1s to Tg (characteristic period), the maximum value of the seismic influence coefficient can be expressed as

[0067] η 2 α max

[0068] η 2 ——Damping adjustment coefficient

[0069] α max ——Related to frequent / rare earthquakes and earthquake intensity

[0070] in

[0071]

[0072] ζ——damping ratio

[0073] The structural damping ratio increases from 0.01 to 0.06, which can reduce about 33.4%, and can effectively reduce the vertical seismic response of the structure. Since the damping of the steel frame structure itself is relatively low, the structural seismic response can be significantly reduced by appropriately increasing the damping ratio on this basis. Therefore, it can be seen that the adoption of this scheme can significantly reduce the structural seismic response.

[0074] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, which should all be included in the scope of the claims of the present invention.
