an investigation of dynamic behavior of coupled steel plate shear walls using cross stiffener under uniform load

In recent decades, the coupled steel plate shear wall system is considered as an efficient lateral force resisting system by engineers and researchers. different parameters affect the nonlinear behaviour of coupled steel plate shear wall system. other models are produced according to the base model. after verifying the nonlinear behaviour of this system by cross stiffeners on the coupled steel plate shear wall, an increase in the thickness of the stiffeners and the thickness of the coupled steel plate shear wall have been evaluated. in this study, the effect of the parameters on the initial stiffness, ultimate strength, and energy absorption by the samples have been compared with each other and the base model. the cross stiffeners on the coupled steel plate shear wall have also increased the sample’s initial stiffness, ultimate strength, and energy absorption. however, the use of stiffeners does not significantly affect the energy absorption by the samples. stiffeners increase the sample’s initial stiffness, ultimate strength, and energy absorption, which has little effect on the energy absorption by the sample.
