     in recent years there is a developing attention to steel plate shear walls (spsws) thanks to their proper function exposing to lateral wind and earthquake loads. furthermore, their application in steel and concrete structures in order to strengthening them has raised a lot of focus upon. in some cases existence of opening is unavoidable due to architectural reasons or installed heating and cooling systems on the walls. that leads to a decrease in capacity and improper functioning of these systems that also results in an intense variation in inplane stress distribution. in this paper impact of circular opening dimensions on behavior of steel plate shear walls has been closely studied. on this purpose using abaqus finite element method a nonlinear analysis has been conducted considering geometrical and material nonlinearity in the models. analyzed models indicate that the reduction factor (1-d/h)s and (1-d/h) respectively for resistance value and stiffness value predict lower error versus the increases in opening diameter.
