摘要
在计算混凝土截面受火时温度场分布的基础上 ,用非线性有限元法对钢筋混凝土构件的防火承截力进行了计算 ,由此得到了其在受火时的时间变形全过程曲线并分析了不同参数对钢筋混凝土构件的防火承截力的影响 ,结果证明该方法能有效地用于分析钢筋混凝土构件和结构的防火性能 .
Based on the temperature distributions in the cross section of the members during a fire calculated by a simplified method. A non linear FE method is used to calculate the fire resistances of RC members. The complete time deformation relation curve of RC members in fire is investigated and the effects of different parameters on the fire resistances of RC members are analysed. The method used here is proved to predict correctly the behaviour of RC members and structures in fire.
