Analyses of thin-walled sections under localised loading for general end boundary conditions - Part 1: Pre-buckling

摘要

The Finite Strip Method (FSM) for pre-buckling analysis of thin-walled sections under localised loading has been developed for general end boundary conditions. For different boundary conditions at supports and locations of applied loads, different displacement functions are required for both flexural and membrane displacements. As the stresses are not uniform along the member due to localised loading, the pre-buckling analysis also requires multiple series terms with orthogonal functions.
