预制装配式混凝土电缆沟节点受力性能分析

Stress Performance Analysis on Prefabricated Concrete Cable Trench Joints

基于ABAQUS有限元平台,提出用于模拟螺栓连接的预制装配式混凝土电缆沟有限元模型,给出参数选取、材料本构接触设置以及边界条件设定等过程的详细说明,通过实际试验与有限元模拟结果对比,得出了模型各阶段荷载位移特征、发展趋势以及所得到的破坏性结果等均与实际试验结果保持较好吻合度等结论。

Based on the ABAQUS finite element platform,the prefabricated concrete cable trench finite element model is proposed for simulation of bolt connection,and the processes such as the selection of parameters,material constitutive contact setting and the boundary condition setting are specified.Based on the comparison of actual tests and the finite element simulation results,it is concluded that the load displacement characteristics of the model,tendency and the destructive results are in good agreement with the actual test results.
