Research on Cooperative Working Performance of Cold-Formed Steel Stud Wall - Steel Frame Structure
Research on cooperative working performance of cold-formed steel stud wall(CFSW) and steel frame(SF) was carried out by analytical method and finite element method. The practical calculation methods of shear force and horizontal displacement for CFSW - SF structure under horizontal load were presented. The superposition principle between CFSW and SF in elastic stage was verified in terms of strength and stiffness. The investigation by FEM indicates that the shear force distribution in elastic stage is in accord with lateral stiffness of CFSW and SF, the shear force distribution rate of CFSW declines along with the increasing of horizontal displacement while thar of SF increases because lateral stiffness of SF degenerates more slowly than that of CFSW.
