Abstract

A semi-supported steel shear wall (SSSW) has been developed in the recent decade, the steel wall is connected to secondary columns that do not carry vertical loads and are used to enable the plate to enter into the post buckling region and develop a tension field. Theoretical research on this system has been performed and an algorithmic method has been developed, which enables the determination of the ultimate capacity of the wall. In this paper results from an experimental investigation of this type of system including two half scale models under cyclic quasi static loading will be presented. These half scale models represent an intermediate storey in a multi-storey steel frame. Hysteresis loops traced from the load deflection curves of these tests have an “S” shape and dissipate energy well. The system has an acceptable level of ductility, which enables its use as a lateral earthquake load resisting system.
