Adopt the steel frame as the structure atress system among the traditional steel construction, structural deformation is big under the lateral force effect, and whole bearing capacity is high inadequately, and anti side performance exists not enoughly. In the cold-bending thin-wall steel structure, the structural function and the architectural decoration function can be realized simultaneously, the lateral resistance comes from the coordinated deformation common stress of the composite wall plate and the cold-bending thin-wall steel skeleton, and the integral rigidity, the bearing capacity, the energy consumption capacity and the ductility of the structure are also insufficient.
Similar to a shear wall structure in a concrete structure, a steel plate shear wall with the function of resisting horizontal lateral force by bearing force in a plane is gradually developed in a steel structure, and the novel lateral force resisting system takes an embedded thin steel plate and an edge beam column member as a basic structural unit. However, experimental studies have found that the sheet steel shear wall structure also has some disadvantages: the hysteresis curve of the test has obvious pinching phenomenon and weak energy consumption capability; the lateral deformation of the structure can generate the out-of-plane deformation of shearing buckling, thereby bringing larger noise and vibration; the wallboard can produce the bucking pulling force area under the large deformation, can bring the burden of additional moment of flexure to the edge post, reduces overall structure's bearing capacity. In addition, the steel plate shear wall can be buckled as long as bearing a small vertical load, and is only used as a horizontal stress component in actual design.
By combining the advantages and the disadvantages of the existing steel structures, a novel high-efficiency stressed steel structure needs to be provided.
