In this paper, elastic buckling and load-resistant behaviors of three different types of steel corrugated plate shear walls (SCPSWs) are compared. The first type is the ordinary SCPSW infilled in a frame structure with its corrugations of a trapezoidal corrugated pattern. The second type is the double-corrugated-plate shear wall (DCPSW) composed of two identical corrugated plates, which are installed in a parallel pattern and are connected with high-strength bolts. The third type is the orthogonal DCPSW (ODCPSW) composed of two identical corrugated plates installed in an orthogonal pattern. By introducing the orthotropic plate model, the rigidity constant formulas of three types of SCPSWs are provided to perform comparison, showing that the rigidity constants could be significantly improved by assembling two corrugated plates. Then, finite element (FE) models of different types of SCPSWs are constructed to perform elastoplastic analyses under in-plane shear loads. The numerical results indicate that the ultimate shear resistance could be remarkably improved by assembling two corrugated plates with high-strength bolts.
