钢筋混凝土有限元模型可用于分析工程结构问题。以渡槽钢筋混凝土模型为例，采用ANSYS中耦合和约束方程法，其中耦合法用于考虑温度场和应力场耦合共同作用产生的应力应变，约束方程法用于将钢筋节点和混凝土节点用约束方程联系起来。对纯混凝土结构以及钢筋混凝土结构的计算结果对比表明：钢筋混凝土有限元模型可以模拟实际钢筋混凝土模型，能为工程安全监测提供可靠的理论依据。

The paper established reinforced concrete finite element model so as to analyze engineering structural problems .Taking aqueduct reinforced concrete model as an example ,it used ANSYS coupling and constraint equations method in process of setting up model .The method considered stress -strain pro-duced by method for temperature and stress fields coupling .The constraint equation method is used to link steel and concrete nodes with constraint equation .The result comparison of pure concrete structure and re-inforced concrete structures contrast showed that the reinforced concrete finite element model can simulate the actual reinforced concrete model and can provide a reliable theoretical basis for engineering safety mo -nitoring.
