摘　　要：在确定碳纤维加固混凝土构件防火方法的基础上,利用有限元分析软件ANSYS对火灾下有防火保护的碳纤维加固混凝土构件的温度场进行分析,并获得构件截面温度分布的规律。结果表明:碳纤维加固构件的温度场计算结果与试验结果符合较好,为进一步研究火灾下有防火保护的碳纤维加固混凝土构件的力学性能和耐火极限创造了条件。The temperature field of insulated carbon＇FRP-strengthened concrete members exposing to fire was analyzed based on determination of fire insulation systems, and the temperature contours of sections were achieved. The calculated results are shown to agree well with the experimental data. It is possible for further researches on the mechanical behavior and fire performance of carbon FRP-strengthened concrete members under fire condition.
