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.
Since early 1970‘s several types of steel plate shear walls are offered in order to use in lateral resistant system of structures. The first vast research program on steel shear panels is carried out by Takahashi and his colleagues in 1973. They have performed some tests with quasi static loading and unloading on stiffened and unstiffened steel shear panels in one or two stories. The initial method for analyzing and designing ofsteel shear walls is commenced with replacement of steel plate with some equivalent diagonal truss elements . Now, the base of recommendations in Canadian steel structures design code about steel shear walls are comply with mentioned method. In the late 1980s, Sabouri and Roberts did their theoretical and laboratory investigations related to steel shear walls which are caused a new method for analyzing and designing of the walls called Plate and Frame Interaction method (PFI). Consequently, results of 16 tests on steel shear panels are given with a low yielding stress steel plates and aluminum plate with opening. s on steel shear panels are given with a low yielding stress steel plates and aluminum plate with opening. The results are redounded to offering reduction coefficient for resistance and stiffness because of openings in the walls .
