Steel plate elements subjected to load in their own plane – buckling factors and critical loads

摘要

The stability of steel plate elements subjected to loading in their own plane is analyzed in the paper. The notion of elastic critical plate buckling stress is explained, and the related buckling factor is defined. The analysis of buckling factor and critical plate element stress for arbitrary boundary conditions, arbitrary stress distribution, and any plate length to width ratio, is presented by means of an analytic procedure and using a specialized computer program EBPlat, which is based on the European standard EN 1993-1-5.
