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