Cyclic Behaviour of Steel Shear Walls with Beam-Only Connection Shear Panels
Steel plate shear walls (SPSWs) with beam-only-connection provide a ductile behavior and reduce damage of columns when subjected to horizontal shear loads. In this study, the effectiveness SPSW with beam-only-connection on failure modes of three-story shear walls with two different types of beam-to-column connections is numerically investigated. The parametric studies are focused on the web plate slenderness and gap between columns. To achieve this aim, a finite element method for simulation and validation has been calibrated according to the recent experimental investigations. Therefore, two different gaps which were constant in the web plate length are selected. In addition, a solid shear panel is chosen as a reference study to compare the numerical results in terms of failure modes and structural behavior. The numerical results illustrated that the maximum shear strength, initial stiffness and energy-dissipating capacity of computational specimens are affected by changing the web plate slenderness and gap between the columns. Finally, the specimen which has improved the failure modes of shear walls is suggested.
