Experimental and Numerical Study of an Innovative Infill Web-Strips Steel Plate Shear Wall with Rigid Beam-to-Column Connections

Steel plate shear walls (SPSWs) offer good energy dissipation capability when subjected to seismic forces as a robust lateral load resisting structure. This research investigated the cyclic behaviors of innovative infill web-strips (IWS-SPSW) and conventional unstiffened steel (USPSW) experimentally numerically. As result, two specimens 1:3 scale three-story single-bay IWS-SPSW USPSW were fabricated tested under loading. Rigid moment-resistant connections used for wall beam-column connection. The with web strips showed high ductility less load-bearing than USPSW. hysteresis results that had no severe beam-columns damages. On other hand, displayed post-buckling, panel cracks, first-floor column Moreover, strength did not fall in test specimen beyond 2.5% average story drift, where structure exhibited great behavior. FE models created validated experimental data. It has been proven can affect an SPSW system’s performance overall dissipation. From parametric study, material features web-strips, such thickness, enhance impact even more.
