The plane models of a six-store steel frame and steel frame-steel plate shear wall with steel plate shear wall(SPSW) in different thickness were established by using the finite element analysis software SAP2000,the structural response of which were analyzed under the eight seldom occurred earthquake,and the impacts of SPSW with different thickness to the steel structure were mainly compared from the aspects of stiffness,natural vibration period and relation of the coping displacement,relative storm displacement of the models.The results shows that SPSW can enhance capacity building of the earthquake obviously,and the coping displacement of the models is decreasing with the increase of the steel's thickness;the structure with the thickness of 8~16mm has the best compatible stain performance.
