摘　　要：在确定材料的热工性能参数,考虑水蒸气等影响的基础上,建立包括升温和降温段的火灾下钢管混凝土柱-钢梁或钢筋混凝土梁连接节点温度场的有限元计算模型。算例分析结果表明,有限元模型计算结果与试验结果总体上吻合较好。Based on the determination of material thermal properties and concerning about the effect of water vapor, a finite element FE model was established and introduced to calculate the temperature field of steel beam or reinforced concrete beam to CFTS column connections during lure. Some testing results were used to verify the rationality and feasibility of the theoretical modeling.
