受火后钢筋混凝土连续箱梁热-结构耦合分析

摘要

Taking the urban viaduct as an example,the paper analyzes box girder temperature field distribution conditions and stress distribution under fire conditions by applying ANSYS finite software,which has provided theoretical analysis for correctly evaluating structural safety condi-tions after fire.%以某城市高架桥为例，采用ANSYS通用有限元软件分析了火灾作用下箱梁的温度场分布情况和应力分布情况，得出的结论为正确评价火灾后结构的安全状况提供了理论依据。
