Analysis of Buckling Property of Portal Steel Plate Shear Wall Member Used for Steel Frame

Abstract

Abstract A set of portal steel plate shear wall members are numerically studied, and effect of some factors on its buckling property and stiffeners used for avoiding its buckling is especially discussed. It is concluded that three stiffening forms presented here have a better effect on the buckling performance of the portal steel plate shear wall member. The buckling coefficient of various portal steel plate shear walls with 6m span are slightly lower than those with 4m and 5m span, which means that the increase of span will reduce the buckling performance and out of plane instability bearing performance of portal steel plate shear walls studied here. The buckling performance requirements can be met by using the stiffening form I as if thickness of the portal steel plate shear wall take as 16mm for the stell framed structures below 10 stories.
