Abstract
This paper presents a novel approach for accurate and efficient planar response analysis of cellular beams, which provides the necessary input for local out-of-plane buckling analysis of web components. The proposed approach utilises the super-element concept defined for unit-cells, achieving further efficiencies through an enhanced Element-Free Galerkin (EFG) approach for establishing the planar super-element response. Several examples are presented, firstly at the level of unit-cells, where the computational benefits of the EFG method are highlighted, and finally at the overall level of cellular beams, where the superior performance of the unit-cell approach with virtually no compromise in accuracy is demonstrated.
