theoretical and numerical study on nonlinear behavior of composite steel plate shear walls

in this paper nonlinear behavior of strengthened steel plate shear walls SPSWs by FRP laminates theoretically and numerically has been investigated in the first part a new method the composite plate frame interaction C-PFI method has been introduced to predict the shear behavior of the composite steel plate shear wall systems CSPSWs. in the second part several models of one -story unstiffened and strengthened SPSWs have been simulated in finite element software and all specimens are subjected to quasi -static cyclic loading.
