摘要

A simple energy method is proposed in this note to predict the thermal post buckling behaviour of uniform columns, with ends immovable axially. The numerical results obtained by using the present method are exactly the same as those obtained by the finite element method and the Rayleigh-Ritz method, using the rigorous nonlinear energy formulations for both the simply supported and clamped uniform columns. The method presented in this note is general, and can be applied to predict the thermal post buckling behaviour of columns with other boundary conditions and with complicating configurations, as long as the ends of the column are immovable axially.
