Abstract |
Corrugated steel plate is a steel plate that is processed to be corrugated in trapezoidal, sinusoidal or circular shapes, and has high flexibility in the corrugated direction and high shear stiffness in the orthogonal direction from the corrugation. Compared to the plate girder, this is economically effective in the regard that it can decrease self-weight when used in the web of the girder. However, shear buckling pattern of the plates and their resistance ability are different according to the different corrugation shapes and their parameter. Therefore, this study conducts liner buckling analysis of trapezoidal plate and sinusoidal plate and analyzes their shear buckling mode and shear buckling stress in order to compare the different shapes' shear buckling patterns and their resistance ability. The result of this comparison shows that the shear buckling stress of trapezoidal shape is bigger than that of sinusoidal shape by up to 30% in the section where local bucking occurs. However, the shear bucking stress of sinusoidal shape is bigger than that of trapezoidal shape by up to 15% in the section where global buckling occurs. |
