Design of perforated plates under in-plane compression

摘要

Post-buckling behaviour and ultimate load capacity of centrally perforated plates with different boundary conditions and subjected to uniaxial or biaxial compression are considered herein. Finite element analysis has been used to carry out extensive studies covering parameters such as plate slenderness, opening size, boundary conditions and nature of loading. A design formula, based on a best-fit regression analysis using the results from the finite element analyses, is proposed for determining the ultimate load carrying capacity. The accuracy of the proposed formula is established by comparing with experimental values of ultimate capacity and also with similar finite element analysis results.
