Sažetak

The paper presents an algorithm for thermal buckling analysis of thin-walled beam-type structures. One-dimensional finite element is employed under assumptions of large displacements, large rotation effects but small strains. Stability analysis is performed in load  deflection manner using co-rotational formulation. The cross- section mid-line contour is assumed to remain not deformed in its own plane and the shear strains of middle surface are neglected. The material properties of the beam are temperature-dependent. Results are validated on test examples.
