Investigation of the effect of Steel Shear Wall on of Steel structures

Steel shear wall (S.S.W) is a new force resisting system against lateral load which had a good performance in laboratories and last earthquakes. In this paper Retrofitting S.S.W on seismic behavior of Steel structures was investigated. In order, some specimens modeled and analyzed. Results showed that thin S.S.W has a good performance in elastic and inelastic zones. Comparing the results obtained nonlinear analysis showed that increasing the infill plate thickness increase elastic stiffness but it decrease the ductility and energy absorption capability. Also stress values applied to boundary frames were major due to post buckling forces in thicker plate. And conclusion of study presented as some recommendations to design of S.S.W.
