Abstract
In order to evaluate the seismic performance of connected steel frame-unstiffened steel plate shear wall structures under cyclic load,this paper systematically analyzed the bearing capacity degradation coefficient,stiffness degradation property,ductility property and dissipation property of web double Angle steel(HPP),flat end plate(HEP)and bolt-welded unstiffened rib(HBP)by load deformation dual control method.The results show that with the increase of loading displacement,the bearing capacity degradation coefficients of the three specimens decrease,and the horizontal load increases first and then decreases.HPP specimens have the smallest reduction of load degradation coefficient and the best stability.With the increase of the overall Angle,the overall horizontal stiffness of the three specimens decreases.HPP has the best stiffness degradation performance.In summary,the HPP connection has outstanding bearing performance and ductility,and can be widely used in shear wall structures.关键词
