| During the past few decades, steel plate shear wall (SPSW) has been used as a lateral load-bearing system in building construction; however, the wall boundary conditions have been considered symmetric and identical in most of the performed projects and researches. In this paper, the Response Modification Factor of this system, when the columns are non-identical, and the effect of changing the dimensions of each boundary element have been investigated. These wall models could be seen when architectural and facility limitations are governing in the design or in the seismic retrofitting of existing structures when boundary elements especially the columns are of non-identical dimensions. Moreover, the necessity of this investigation would be important concerning the role of the Response Modification Factor in seismic design of structures. In this study, the effect of changing the dimensions of boundary elements on the Response Modification Factor of steel plate shear wall was calculated using Uang’s method and Newmark & Hall’s method. The same study has also been performed on ductility, energy absorption, and ultimate strength. | ||
