In this study, the shear buckling strengths of the trapezoidal and sinusoidal corrugated plates with the same self-load were compared, and their characteristics and tendencies were analyzed. In the preceding comparative study of corrugation shapes, the corrugation wave depth and the corrugation wave angle were the same. As these target, A linear buckling analysis was conducted, and the differences in the shear buckling mode and the buckling stress were analyzed.
