Problems solved by technology

This advantage has a good effect for moderate and strong earthquakes, but for more frequent small earthquakes, the non-stiffened thin steel plate shear wall may also buckle, and the structure can still provide better energy dissipation capacity at this time, but the initial The stiffness drops more and needs to be repaired, but it is not economical
At the same time, due to the good ductility of the steel plate shear wall, the residual displacement of the structure after the earthquake may be relatively large, which further increases the difficulty of post-earthquake repairs

Embodiment 1

[0047] This embodiment provides a self-resetting assembled steel plate shear wall based on SMA, which includes two structural columns 1, at least two I-beams 2 are arranged in parallel between the two structural columns 1, and any adjacent two An embedded steel plate 3 is installed between the root I-shaped steel beams 2, and the embedded steel plate 3 has at least one set of parallel opposite sides; a set of parallel opposite sides of the embedded steel plate 3 are fixed on two On the I-beam 2, there is a distance between the structural column 1 and the embedded steel plate 3;

[0048] The embedded steel plate 3 is also provided with an SMA strand 5 unit, the SMA strand 5 unit includes an SMA strand channel 4 and an SMA strand 5, and the SMA strand channel 4 includes two parallel Stiffeners on the embedded steel plate 3, the SMA stranded wire 5 is located in the SMA stranded wire channel 4, and the two ends are respectively fixed on the embedded steel plate 3 and the SMA stra...

Embodiment 2

[0064] The difference between this embodiment and Embodiment 1 is that: the SMA strand 5 units are arranged on both sides of the embedded steel plate 3, and the SMA strand 5 units located on one side of the embedded steel plate 3 are connected to the The SMA strand 5 units on the other side of the embedded steel plate 3 intersect in space.

[0065] The SMA strand channels 4 are arranged on both sides of the embedded steel plate 3, forming cross stiffeners in a disguised form, further improving the lateral stiffness of the embedded steel plate 3, and at the same time making the SMA strands 5 on both sides alternately stretched and compressed without interfering with each other .

Embodiment 3

[0067] The difference between this embodiment and embodiment 2 is: as figure 2 with image 3 As shown, the self-resetting assembled steel plate shear wall also includes a plurality of auxiliary connection devices 9, the first side of the auxiliary connection device 9 is bolted to the I-beam 2, and the auxiliary connection device 9 The second side of the second side is bolted to an edge stiffener 8 of the embedded steel plate 3; the second side of the auxiliary connecting device 9 is also fixed with one end of the SMA strand 5.

[0068] Due to the arrangement of the auxiliary connection device 9, the contact area between the polygonal embedded steel plate 3 and the I-beam 2 is wider, and the connection between the polygonal embedded steel plate 3 and the I-beam 2 is more reliable.

[0069] In a specific implementation, the auxiliary connection device 9 includes a triangular steel plate and a right-angled triangular frame body welded by three-sided steel plates, and the triang...

Description

technical field [0001] The invention relates to the technical field of assembled anti-seismic structural systems, in particular to an SMA-based self-resetting assembled steel plate shear wall and a construction and installation method thereof. Background technique [0002] Since the steel plate shear wall was proposed, the development of the steel plate shear wall system has gone through the process from thick steel plate shear wall to thin steel plate shear wall, and then to buckling-constrained steel plate shear wall. The existing steel plate shear wall system is divided into three types according to the different mechanical properties of the embedded wall panels: thick steel plate shear wall, thin steel plate shear wall, buckling restrained steel plate shear wall (including stiffened steel plate shear wall and buckling-resistant plate Shear wall), steel plate-concrete composite steel plate shear wall and other types of steel plate shear wall (including open hole steel pla...
