Summary

This paper presents an algorithm for thermal buckling analysis of thin-walled beamtype structures. A one-dimensional finite element is employed subject to the assumptions of large displacements, large rotational effects but small strains. The geometric stiffness matrix of the thin-walled beam finite element is derived. Stability analysis is performed in a load deflection manner using the co-rotational formulation. The cross- section mid-line contour is assumed to remain undeformed in its own plane and the shear strains of the middle surface are neglected. The analysis is restricted to constant material properties. The results are validated on test examples.
