The composited variable-thickness buckling-restrained steel plate shear wall (BR-SPW) is suitable for the structural engineering field.

Description

technical field [0001] The invention relates to a composite shear wall component, in particular to a composite variable-thickness anti-buckling steel plate shear wall. Background technique [0002] Under the action of earthquakes, how to reduce structural damage, improve the ability of structures to resist rare and extremely rare earthquakes, and improve the recoverability of structural system functions and the repairable performance of structural systems are current research hotspots in engineering earthquake resistance. Seismic technology is one of the most effective ways to achieve the above requirements. This technology is to set energy-dissipating components in the engineering structure to dissipate the energy input into the structural system, so that the main plastic deformation of the structure is concentrated in the energy-dissipating components, thereby avoiding serious damage to the main structure. With the increasing number of high-rise shear wall structures, the...

AI Technical Summary

Problems solved by technology

[0003] The present invention solves the problem that the core plate of the existing steel plate shear wall is a steel plate of equal thickness, which is subjected to complex stress, and the yield energy dissipation section is affected by the secondary processing of welding and cutting, which increases the initial defect of the core plate itself, resulting in energy dissipation capacity. In order to solve the problem of instability, a composite variable thickness buckling-resistant steel plate shear wall is proposed
