| Abstract | ||
| Steel plate shear walls (SPSW) are considered one of the most common and acceptable lateral resisting structural systems for steel structures due to their excellent seismic performance. This system offers several advantages over the other usual lateral load resisting systems such as the conventional braces. Steel saving, installation easiness, reduced foundation cost, and providing major stiffness against building drift are some apparent advantages of the steel plate shear walls. This paper describes and investigates the effect of using steel plate shear walls on the behavior of steel frames. Therefore, finite element (FE) analysis was adopted using ABAQUS software to simulate two steel frames equipped with a steel plate shear wall and conventional brace under cyclic loads. Eigenvalue buckling analysis was conducted as a preliminary analysis and the results were introduced to define the initial imperfection for a realistic simulation. The important seismic parameters including the lateral stiffness, the ultimate shear capacity, energy dissipation, and ductility are investigated using static nonlinear analysis after confirming a good agreement with the results of nonlinear dynamic analysis of the laboratory sample. The numerical results indicated that using SPSW as lateral-load resisting gives higher stiffness, ultimate strength, higher ductility and energy absorption than the conventional brace frame. | ||
