摘要：

Finite element method is applied for the calculations of temperature fields of concrete filled steel tubes under fire. A theoretical model that calculates deformations and strength of beam-column in fire and fire resistance is described in this paper. A comparison of results calculated using this model with the results of tests, there is good agreement. Based on the theoretical model, influence of the changing strength of the materials, sectional dimensions, steel ratio, eccentricity of the load and slenderness ratio on the fire resistance is discussed.
