Shear resistance and design of horizontally-placed stiffened corrugated steel plate shear walls

Uniformly disposing stiffeners on both sides of the corrugated steel plate could enhance the seismic performance of the corrugated steel plate wall. This paper addressed the shear resistance design of stiffened corrugated panels in horizontally-placed stiffened corrugated steel walls (HSCSWs). Three half-scale, one-story, single-bay specimens were fabricated and tested under lateral cyclic loads, each featuring a distinctive design for the infill plates. Grounded on the test observations and results, the influence of the arrangement of vertical stiffeners and the quantity of vertically arranged stiffeners on the hysteretic performance of HSCSWs was evaluated. Subsequently, finite element (FE) models of the specimens were constructed and verified in accordance with the test results. Based on the validated FE models, key parameters affecting the lateral load-bearing performance of HSCSWs were selected and parametric analyses were carried out. By introducing the normalized aspect ratio, design formulas were recommended for the yield shear strength and ultimate shear strength of HSCSWs. It was found that the proposed design formulas could furnish precise and safe estimations of the shear resistances for the test specimens, thereby enabling them to provide crucial reference for the design of HSCSWs.
