摘要
为了对工程中存在的无粘结预应力混凝土箱型梁的承载力做出正确评价,提出了无粘结预应力混凝土箱型梁的非线性有限元计算模型,利用非线性有限元软件ANSYS对2个工程实例梁的承载性能分别进行了分析,并将计算结果与现场静载试验的结果进行对比,两者吻合较好,可供设计参考。
In order to evaluate correctly the bearing capacity of unbonded prestressed concrete box girder in engineering, a nonlinear finite element computational model for tmbonded prestressed concrete box girder was presented. Then the bearing capacity of two box girders in engineering were analyzed respectively by using the nonlinear finite element software ANSYS. The calculated results were compared with the field static load test results, and they agreed well with each other, which provide effective basis for the evaluation of the bearing capacity of the two box girders.
