Elastic Shear Buckling Characteristic of Trapezoidally Corrugated Plates

Recently, the applications of corrugated plates(or folded plates) are increasing due to economic and structural advantages in certain situations. And, because of the higher strength of corrugated plates than flat plates, the usage of the corrugated plates is increasing. So there are many necessities for specifications of corrugated plates. For flat plates, there are many design details in almost specifications. However, there are no detail design guides such as shear strength except the bending strength and the normal strength. So, it is difficult for engineers to design structures consist of corrugated plates. Therefore, a provision is necessary for engineers to refer for designing corrugated plates. The conclusion of this study shows a formula that helps to determine the shear strength of corrugated plates under various geometric conditions ; the size of corrugation ; the curvature of corrugation and ; the thickness of the corrugated plate. Also, it shows that corrugated plates have higher shear buckling strength than flat plates.
