Abstract: In this paper, the stability analysis method of the elastic beam-column under a load of high temperature is deduced from normal temperature and taking the beam-column with a protective layer in high temperature under the action of uniform load and concentrated load as the example. We analysed the variation law of the stability of the beam-column with temperature changed and use the ANSYS software to analyse the stability of the beam-column with the same condition, and verified the correctness of the method we deduced. Through stability analysis, the stability of the structure under the uniform load is better than that under the concentrated load.

Keywords: beam-column; strength stability; thermo-solid coupling.
