Abstract

This paper presents an analytical approach for prebuckling and buckling analyses of thinwalled members implemented within the framework of the Generalised Beam Theory GBT With the proposed GBT crosssectional analysis the set of deformation modes used in the analysis is represented by the dynamic modes obtained for an unrestrained frame representing the crosssection In this manner it is possible to account for the deformability of the crosssection in both prebuckling and buckling analyses Different loading conditions including both axial and transverse arrangements are considered in the applications to highlight under which circumstances the use of the GBT deformation modes is required for an adequate representation of the prebuckling and buckling response The numerical results have been validated against those determined using a shell element model developed in the finite element software ABAQUS
