Experimental and numerical study on vertically-placed stiffened corrugated steel plate shear walls

This paper focuses on the experimental investigation of vertically-placed stiffened corrugated steel walls (VSCSWs). Quasi-static cyclic tests were conducted on three half-scale, one-story, single-bay steel shear walls with unstiffened corrugated plate, and stiffened corrugated plates with one or two pairs of horizontal stiffeners. Based on test observations, this paper elucidated the failure modes of diverse specimens and conducted a comparative analysis of their hysteresis performance. Then, the finite element models of the specimens were constructed, and their accuracy was validated using the test results. Subsequently, a series of parametric analyses were conducted to further investigate the effect of several important geometric parameters on the hysteretic behavior of VSCSWs. Both experimental and numerical results show that adding horizontal stiffeners to vertically-placed corrugated steel plate shear walls is an effective way to improve their lateral load-bearing capacity and energy dissipation performance.
