Background
The lateral force resisting structure is an indispensable stress component in high-rise and super high-rise buildings, plays a role in resisting horizontal loads such as wind load, earthquake load and the like, and is the key for ensuring the safety and reliability of the whole building. The lateral force resisting structure used in high-rise and super high-rise steel structure buildings at present mainly comprises structures such as a central brace, an eccentric brace, a buckling restrained brace, a steel plate shear wall and the like.
Because the wind load and the earthquake load borne by the high-rise building are strong, and the section required by the support is usually large, the main frame spans can be arranged in one direction, and the central support, the eccentric support and the buckling restrained support have the problem of high performance. The buckling resistance of the central brace is poor, and particularly, under the action of medium and large earthquakes, elastic or elastic-plastic buckling inevitably occurs to cause failure of the brace, so that the structural rigidity and the energy consumption capability are reduced, and the structural safety is influenced. The eccentric brace forms the power consumption through supporting the biasing and links the roof beam and consume energy, can alleviate the bucking problem of vaulting pole, nevertheless power consumption beam section warp and just means that the floor can take place to destroy earlier to in order to guarantee that power consumption beam section yields at first, all the other components often need design into too big cross-section, and excessive superstrong increases construction cost, and practical application is comparatively limited. The buckling restrained brace is a brace which achieves the effect of limiting the buckling of a core material by wrapping a restrained material or a member outside a brace core material, belongs to the category of 'structural buckling prevention', and has stronger buckling resistance and better energy consumption capability.

The steel plate shear wall provides rigidity and resists horizontal force through the pulling force field that the wallboard formed, but the pulling force field has very unfavorable slant effect to the side column of steel plate wall, and because wallboard compressive capacity is weak, the produced couple that topples moment of horizontal load mainly forms by frame post axle power is resisted, make internal force in the post very big, lead to the unstability or the destruction of frame post very easily, consequently need additionally increase the post cross-section or select for use the better integrated configuration post of stability as the edge restraint component, this application in the steel construction of steel plate shear wall has also been restricted. In addition, the bending deformation of the frame beam under the action of a tension field formed by the upper and lower layers of wallboards can be inhibited to a great extent and is similarly embedded, so that the plastic development of the frame beam is difficult, the requirement of a strong column and a weak beam in the anti-seismic design is difficult to realize, and the anti-seismic performance of the whole structure is reduced. In addition, the wall plate of the steel plate shear wall needs to be connected with the frame beam column through bolting or welding on the construction site, the workload is large, the connection quality is not easy to guarantee, and the assembly application of the steel plate shear wall structure is hindered.
