AI Technical Summary

Problems solved by technology

However, considering the amount of steel used and the self-weight of the structure, the steel plate of the steel plate shear wall widely used at present is relatively thin, which causes the shear wall to be prone to instability under the action of lateral load, which affects the wind resistance and earthquake resistance of the steel plate shear wall. Performance poses many problems

The study found that the hysteresis curve of the steel plate shear wall structure is pinched under the earthquake load, and the energy dissipation capacity is not ideal; because the existing steel plate shear wall is prone to instability, it needs to rely on the steel plate to form after the instability in the process of lateral resistance. However, the formation of the tension field will form a large force on the beams and columns of the outer steel frame of the shear wall, so it is necessary to increase the beam-column section of the outer steel frame; During the process of load and strong earthquake, the instability of the steel plate will cause a loud sound, which will bring people a very uncomfortable feeling; during the construction process, the vertical load generated by the upper rear installation structure will cause the lower column Axial compression deformation, so the steel plate shear wall at the lower part of the structure actually bears a certain vertical load. Since the steel plate shear wall is thin, this load may lead to compressive buckling of the steel plate shear wall

In order to avoid the above problems of steel plate shear walls, researchers have proposed many solutions, such as using thick plates, setting stiffeners, etc., but these measures also bring heavy weight (steel consumption), complex structure, and welding workload. Major and other issues
