摘要
利用ABAQUS有限元软件分析火灾后钢筋混凝土梁的温度场,并与原模型试验结果进行比较,在此基础上分析其受弯承载力变化,得出钢筋混凝土梁高温后力学性能的变化特征,结论为钢筋混凝土结构火灾后的加固提供参考。
Firstly,the paper analysed the temperature-field of a reinforced concrete ABAQUS Finite Element Software,and proved its reasonable by comparing with the further analysed the mechanical properties changes of the reinforced concrete beam after provide a reference for reinforcement of the reinforced concrete structure after fire. beam after experiment fire by the results, then fire,the conclusion can
