Experimental and Numerical Study on Shear Behavior of Stiffened Thin Steel Plate Shear Walls by New Welding Process

Steel plate shear walls (SPSW) structures have been widely employed in multistory residential buildings. The traditional welding process may lead to serious deformation due the thinness of plate. In this study, a new is proposed ensure that stiffeners and SPSWs bend as whole, number welds reduced from 3 2. This has better integrity than owing less residual stress deformation. On basis low-cycle reciprocating load tests on four full-scale specimens, failure pattern, hysteresis characteristics, load-carrying capacity affected by are studied, used vertical stiffener can meet requirements capacity. influences various parameters resistance made compared analyzed. results indicate lateral stiffness frame width–height ratios wall significantly influence SPSWs. adopting manufacturing numerically simulated using ANSYS software. same conclusions be obtained comparing numerical with experimental results.
