Abstract:

Finite element method is applied for the calculations of temperature fields of concrete filled steel tubes under lire. 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 shows good agreement. Based on the theoretical model, the influence of the changing strength of the materials, sectional dimensions, steel ratio, load eccentricity and slenderness ratio on the firs resistance are discussed. The theoretical model in this paper was used to provide data on the necessary fire protection measures for the concrete filled steel tubular columns used in a high-rise building, SEG Plaza in Shen-Zhen City, southern China.
