MECHANICAL BEHAVIOR STUDY OF STEEL PLATE SHEAR WALLS WITH CHANNEL STIFFENERS

Abstract

Abstract

Steel plate shear wall ( SPSW) with channel stiffener consists of infill steel plates，boundary elements and symmetric channel stiffeners． The channel stiffeners with a greater flexural rigidity can provide out-plane restraint effectively． It was carried out buckling analysis and elastoplastic analysis of the mechanical behavior of SPSWs with channel stiffeners by ABAQUS． The analytical results show that the distance between channel stiffeners and boundary elements has influence on the out-plane deformation of SPSW，but no influence on critical buckling stress and lateral load capacity of the SPSW． The channel stiffeners can increase the critical buckling stress effectively． With the decrease of width-to-thickness ratio and aspect ratio，the load capacity and stiffness of SPSW increase greatly． In order to increase the stiffness of SPSW，the stiffener-to-plate stiffness ratio should be greater than 20． In order to prevent the greater deformation and premature failure of the columns，the columns must have enough stiffness． The stiffness of SPSW increases and degrades slowly with the increase of the stiffness of column．
