Description

Technical Field

[0001] The invention belongs to the technical field of building structures, and in particular relates to a self-resetting steel-frame concrete frame with a swing wall and an assembly method thereof. Background Art

[0002] In recent years, steel-reinforced concrete structures have been widely used in large public buildings, multi-story building structures and complex industrial buildings because they have the advantages of large bearing capacity, high rigidity and good seismic performance compared with traditional reinforced concrete structures; compared with steel structures, steel-reinforced concrete has the advantages of good durability, good fire resistance, good integrity and saving steel materials. However, steel-reinforced concrete structures often bear large loads. Under strong earthquakes, the frame column base and beam-column joints are prone to serious damage, which in turn causes serious economic losses and casualties, and has an adverse impact on people's normal production. With the continuous development of structural seismic technology, the use of swing walls for structural shock reduction has been applied in actual engineering in recent years. For structures with swing walls, the swing walls produce swinging motion in a certain horizontal direction of the structure under the action of earthquakes. The swing energy dissipation reduces the inter-layer displacement of the main structure and makes the inter-layer shear force distribution more balanced, avoiding serious damage to the structure; however, the seismic performance of frame structures with single swing walls still has great limitations. For example, the frames on both sides of the swing wall will be too rigid, which makes it difficult to achieve deformation coordination between the frame and the swing wall when the swing wall swings.

[0003] In recent years, achieving post-earthquake structural function recovery has become a new concept in structural seismic design, and has been greatly innovatively developed. Various types of seismic toughness structures or components have been proposed, such as self-resetting frames, replaceable energy dissipation beams, self-resetting shear walls, and self-resetting swing columns, among which the self-resetting swing column is a new type of energy dissipation and shock-absorbing column. The swing column relaxes the constraint between the column foot and the foundation, allowing a certain lift at the interface between the column foot and the foundation under the action of the horizontal overturning moment, while the damper achieves the purpose of energy dissipation and shock absorption. The swing column not only has a large deformation capacity because the node of the column foot can be hinged, but also can reset itself. If it is applied to the frame structure, it can not only achieve the coordinated work of the frame and the swing wall, but also greatly improve the energy dissipation capacity of the structure.

[0004] Based on this, a steel-reinforced concrete frame that combines the advantages of a rocking wall with good energy dissipation capacity and the functional recovery of self-resetting components is necessary and has important engineering significance. Summary of the invention

[0046] The present invention is described in detail below in conjunction with specific implementation modes.

[0047] like Figure 1 As shown, the present invention includes three parts: steel frame concrete frames on the left and right sides and a swing wall YBQ in the middle. The steel frame concrete frames on the left and right sides include two steel frame concrete columns and two steel frame concrete beams. The steel frame concrete columns are connected to the steel frame concrete beams through beam-column nodes LJD.

[0048] The swing wall YBQ is connected to the frames on both sides through four flexible supports ZC;

[0049] A column base node ZJD is set at the bottom of the steel-reinforced concrete column, and the column base node ZJD is connected to the foundation through anchor bolts.

[0050] like Figure 2 As shown, the steel-reinforced concrete column includes a steel section ZJD1, an outer steel ZJD2 is arranged at the bottom of the column, and ribs and ear plates are welded around the top of the outer steel ZJD2; the bottom of the outer steel ZJD2 is installed at the corresponding position of the box-type base ZJD6 welded by steel plates through a limit block ZJD5; the limit block ZJD5 adopts the design concept of a cup-shaped foundation, which can allow the column to rotate to a certain extent, and at the same time can resist the bottom shear force to limit the horizontal displacement of the bottom of the column, and can provide a certain self-resetting ability for the column, and the limit block ZJD5 is anchored on the box-type base ZJD6 by bolts;

[0051] To limit the column from tilting, Figure 3 The shear damper ZJD4 shown in the figure has its two ends anchored to the outer steel ZJD2 and the box-type base ZJD6 by bolts. In order to enhance the self-reset capability of the rocking column, a vertical SMA device is set around the rocking column. One end of the SMA is anchored to the rib plate of the outer steel ZJD2, and the other end is anchored to the base ZJD6. An SMA is set on both sides of the four dampers ZJD4. Under the action of earthquake, the SMA limits the column from tilting by stretching, and the base is fixed to the foundation beam by anchor bolts ZJD7.

[0052] like Figure 4 , 5 , 6; the beam end is connected to the short beam extending from the rocking column through the beam-column node LJD; the beam-column node LJD includes a left connecting member LJD6 and a right connecting member LJD7; at the node, the connecting members LJD6 and LJD7 are respectively connected to the beam end steel and the short beam steel;

[0053] The left connecting piece LJD6 includes a left channel steel LJD601 and two left rib plates LJD603. Screw holes are left on the web of the channel steel. The two left rib plates LJD603 are welded to the web at intervals. Concentric circle pin holes are opened on the two left rib plates LJD603. The right connecting piece LJD7 includes a right channel steel LJD701 and a right rib plate LJD702. Strip holes are opened on the right rib plate LJD702. The connecting pieces LJD6 and LJD7 are connected by a pin shaft LJD602 to realize the rotatable node. At the same time, the strip holes on the vertical plate allow the two beam sections to undergo axial expansion and contraction deformation.

[0054] At the upper and lower flanges of the connector, a weakened steel plate LJD3 is provided, such as Figure 4 As shown, strip holes are opened at both ends of the weakened steel plate LJD3; bolts LJD2 pass through the strip holes of the steel plate, the holes in the flange of the channel steel, and the holes in the flange of the steel section, and are anchored at the upper and lower ends of the node; the weakened steel plate LJD3 provides damping when the node rotates and deforms axially, thereby enhancing the energy absorption capacity of the node; an L-shaped angle steel LJD4 is arranged on the left and right sides of the inner sides of the upper and lower flanges of the steel beam, and an SMA energy absorption rod LJD5 is arranged on the angle steel; when the node rotates and deforms axially, the SMA energy absorption rod enhances the energy absorption capacity and self-resetting capacity of the node through tension and compression.

[0055] In order to control the lateral deformation of the frame, distribute the shock waves to each floor through its overall displacement, and give full play to the overall energy dissipation performance of the frame under earthquake, a controllable flexible support ZC is set between the frame and the rocking wall YBQ. When the frame is deformed, the earthquake wave is transmitted to the rocking wall YBQ through the controllable flexible support ZC. At this time, the controllable flexible support ZC is axially telescopically deformed and provides restoring force to the frames on both sides of the rocking wall. At the same time, it also provides damping force when it is axially deformed to consume earthquake energy.

[0056] like Figure 7 , 8 As shown in Figures 9 and 10, the two ends of the support ZC are respectively hinged to the swing wall YBQ and the swing column through the connecting base ZC2; the connecting base ZC2 includes a bottom plate and two vertical plates, screw holes are left on the bottom plate, and the two vertical plates are welded to the bottom plate at intervals. Concentric circle pin holes are opened on the two vertical plates, and the bolt ZC1 anchors one end of the connecting base ZC2 to one side of the swing column through the screw hole of the bottom plate, and fixes the other end to one side of the swing wall;

[0057] The inner side of the connecting base ZC2 is connected to the conical connecting piece ZC3 through a pin shaft, and a left sleeve ZC5 and a right sleeve ZC7 are arranged between the two conical connecting pieces ZC3; one end of the left sleeve ZC5 and the right sleeve ZC7 are respectively embedded in the hollow position inside the conical connecting piece ZC3; the top and bottom of the sleeve are connected to the conical connecting piece ZC3 through bolts ZC4;

[0058] One end of the right sleeve ZC7 is embedded in the groove of the wall of the left sleeve ZC5, and the limiter ZC6 is installed at the reserved strip hole of the embedded part of the two sleeves; a core rod ZC8 with a disc spring is arranged inside the support.

[0059] The two sleeves are slidably connected, and the overlapping part of the two sleeves has a long strip hole axially opened on the wall of the sleeve. A limit screw is inserted into the hole and anchored at both ends to limit the axial sliding of the two sleeves; this can not only realize the axial deformation of the support ZC, but also limit the excessive axial deformation of the support ZC.

[0060] The circular top plate at the left end of the sleeve ZC5 has a circular hole with the same inner diameter as the core rod diameter, and the left end of the core rod ZC8 extends into the hole; the sleeve ZC7 has a circular hole at one end like ZC5, and the hole diameter is the same as the outer wall diameter of the top cylinder ZC11. The end plate ZC10 is composed of a circular bottom plate and a steel pipe welded on the bottom plate, such as Fig.10 As shown, the steel pipe section is embedded in the circular hole at one end of the sleeve ZC7, and the top tube ZC11 is embedded in the circular hole of the sleeve ZC7 and wraps the steel pipe section of the end plate ZC10.

[0061] like Fig.11 , 12As shown in 13, the bottom of the swing wall YBQ1 is provided with an outer steel YBQ2; ribs and ear plates are welded at both ends of the top of the outer steel YBQ2, and a steel frame is welded at the bottom, and two grooves are opened in the middle of the bottom of the steel frame; the wall wrapped with the outer steel is embedded in the cup-mouth foundation YBQ6, and a bottom embedded steel plate YBQ9 is set between the bottom of the outer steel YBQ2 and the cup-mouth foundation YBQ6, and the trapezoidal ribs on the bottom embedded steel plate YBQ9 are just embedded in the bottom grooves of the outer steel. The trapezoidal ribs on the bottom plate YBQ9 can resist the bottom shear force while the swing wall is rotating, preventing the swing wall from shifting sideways;

[0062] The rubber pad YBQ8 is buried in the gap between the outer steel YBQ2 and the foundation to play a buffering role when the wall sways. The SMA device is anchored between the outer steel YBQ2 ribs and the embedded steel plate YBQ7 on the top of the foundation. The SMA device includes an SMA rod YBQ3, the bottom of the SMA rod YBQ3 is anchored to the embedded steel plate YBQ7 on the top of the foundation through the SMA rod bottom fixing piece YBQ4 and the SMA rod bottom fixing piece anchor bolt YBQ5; the top of the SMA rod YBQ3 is anchored to the outer steel YBQ2 ribs through bolts.

[0063] The SMA device is constructed as Fig.14 As shown in the figure, the SMA device increases the energy dissipation capacity of the rocking wall by stretching and compressing when the wall tilts, and provides a certain self-reset capability. The application of cup-shaped foundation and SMA device can greatly improve the self-reset capability of the rocking wall. The application of a large number of anchors can realize the replacement of damaged nodes and energy-absorbing components after the earthquake.

[0064] The assembly method of the self-resetting steel-framed concrete frame with a swing wall of the present invention comprises the following steps:

[0065] Step 1: Place the outer steel of the column foot with welded ribs in the corresponding position, assemble the column foot damper, limiter, SMA rod base, and then hoist the I-beam to the corresponding position of the column foot;

[0066] Step 2: Assemble the beam-column joints and cast the frame after it is assembled;

[0067] Step 3: After the outer steel cladding and foundation of the swing wall are completed, the swing wall is hoisted to the corresponding position;

[0068] Step 4: Install the SMA rod between the outer steel ribs of the swing wall and the pre-buried steel plates of the foundation;

[0069] Step 5: Lift the support section and fix it to the corresponding position of the column and the swing wall to complete the assembly.

[0070] The working principle of the present invention is as follows:

[0071] During a small earthquake, the frame column foot node mainly dissipates energy through the stretching and compression of the SMA rod and the shear damper. The beam-column node mainly dissipates energy through friction by the weakened steel plate. Similarly, the swaying wall mainly dissipates the seismic energy transmitted from the frame part by the expansion and contraction of the SMA rod. During a moderate and large earthquake, the column foot swings within the constraint range of the limit block. At the same time, the shear damper and the SMA rod participate in the work and dissipate the seismic energy together. At the same time, the SMA rod provides restoring force for the frame column through stretching and compression. At this time, the beam-column node rotates, and the weakened steel plate further develops from the friction energy dissipation in the first stage to plastic deformation energy dissipation. The SMA rod arranged at the inner flange of the steel provides restoring force for the node through stretching. When the frame deforms, the disc spring in the support transmits the seismic wave to the swaying wall through compression. At this time, the swaying wall swings in the cup-shaped foundation to dissipate energy. The rubber pad filled on the inside of the foundation plays a buffering role. The SMA rod fixed at the outer steel part constrains the swing of the swaying wall through tension on the one hand, and provides restoring force for the swaying wall on the other hand. After an earthquake, the shear dampers and SMA rods at the column base, the SMA rods at the beam-column joints, the weakened steel plates and supports, and the SMA rods at the rocking walls can all be replaced if damaged.
