New Interaction Equation for Plate Buckling(Welding Mechanics, Strength & Design)

Search this article


This paper is concerned with proposal of an accurate elastic buckling interaction equation for simply supported rectangular plates subjected to five load components such as compression and bending in two directions and shear. In order to construct this interaction, data on buckling strength of plate under two load components partly calculated in the present study and partly obtained from existing ones are first taken, and then buckling interaction relationships for any two load components are developed. Based on these relationships, the new buckling interaction equation for five load components is theoretically derived. Assessment of accuracy is performed and it is found that the proposed equation has sufficient accuracy for practical designs. Some comparisons are also made with the interactions proposed by Lloyd's Register and Det Norske Veritas. The result indicates that the new interaction equation proposed in this paper yields better accuracy in safety side.
