Thin-walled sections under localised loading may lead to buckling of the sections. This paper briefly introduces the development of the Finite Strip Method (FSM) for budding analyses of thin-walled sections under localised loading for general end boundary conditions. This method is benchmarked against the Finite Element Method (FEM).
For different support and applied loading conditions, different functions are required for flexural and membrane displacements. In Part 1- Pre-buckling described in the companion paper, the analysis provides the computation of the stresses for use in the buckling analyses in this paper. Numerical examples of buckling analyses of thin-walled sections under localised loading with different end boundary conditions are also given in the paper in comparison with the FEM.
