Description

technical field [0001] The invention relates to the field of structural engineering, in particular to the field of industrialized assembled structures. Background technique [0002] Due to its advantages of high material strength, good plasticity and toughness, low structural weight, excellent seismic performance, fast construction speed, and steel can be recycled, steel structure buildings are being gradually applied and promoted. [0003] The building structure needs to bear the vertical self-weight load and lateral force such as wind and horizontal earthquake during use. In the traditional steel structure, the steel frame is used as the structural stress system, and the structural deformation is large under the action of lateral force, the overall bearing capacity is not high enough, and the lateral resistance performance is insufficient. In the cold-formed thin-walled steel structure, the structural function and architectural decoration function can be realized at the s...

Problems solved by technology

However, the experimental research found that the thin steel plate shear wall structure also has some shortcomings: the test hysteresis curve has obvious "pinching" phenomenon, and the energy dissipation capacity is not strong; the shear buckling out-of-plane deformation will occur under the lateral deformation of the structure, with Larger noise and vibration; under large deformation, the wall panel will produce buckling tension band, which will bring additional bending moment burden to the edge column and reduce the bearing capacity of the overall structure

In addition, the steel plate shear wall will buckle as long as it bears a small vertical load, and it is only used as a horizontal force member in actual design
