摘　　要：为研究采用防火装饰一体化构造的钢梁在火灾下的温度场和承载力,通过基于ANSYS软件建立的分析模型对不同截面尺寸和不同耐火极限的钢梁进行抗火性能研究,并给出了计算钢梁承载力的简化公式,公式计算结果与有限元结果吻合情况较好。In order to study the temperature field and bearing capacity of steel beams with integrated fire protection and decoration structure under fire,the fire resistance performance of steel beams with different cross-sectional sizes and different fire resistance limits was studied through an analysis model based on ANSYS software,and a simplified formula for calculating the bearing capacity of steel beams were given.The formula calculation results are in good agreement with the finite element results.

关 键 词：防火装饰一体化钢梁 抗火性能 有限元计算
