| Divided low-yield point steel plate shear wall is composed of rectangular frame and embedded steel plate composed of ribbed beams and columns.It is a lateral resistance system with multiple seismic lines.This paper simulated the seismic action of divided shear wall by finite element method.The main research contents as follows:(1)Five divided point steel plate shear walls with low yield point were simulated by ABAQUS finite element software,and mechanical properties,hysteretic properties,stiffness degradation and energy dissipation capacity were analyzed.The seismic performance of divided low-yield steel plate shear wall were researched as well.(2)Using ABAQUS finite element analysis software,the hysteretic behavior of divided lowyield steel plate shear walls under different layout and thickness parameters is calculated,and then analyzed the damage performance.It is import that a double-parameter cumulative damage model of deformation and energy dissipation is proposed.(3)The finite element model of divided low-yield point steel plate shear wall embedded in steel frame is established.Furthermore,structures’ hysteretic behavior,energy dissipation capacity,energy dissipation mechanism and failure mode are studied.The results show that divided low-yield point steel plate shear wall and steel frame has great cooperative performance.Divided low-yield point steel plate shear wall could improve the lateral resistance and energy dissipation performance significantly. |
