顷应力混凝土结构在ANSYS中的实现与比较

运用大型通用商业软件ANSYS模拟预应力混凝土在施工阶段的工作状况，分别采用实体切割法、节点耦合法、约束方程法三种方法建立几何模型，预应力的施加采用初应变法和降温法，对这几种方法组合进行了比较，并通过比较给出降温法施加预应力时的温度放大参考系数。

The implementation and comparison of the prestressed concrete structure in ANSYS

In this paper the large general commercial software ANSYS was used to simulate the prestressed concrete working conditions in the construction phase.The entity cutting method,the node coupling method,the constraint equation method three ways were used to build geometric models.The initial strain method and the cooling method were used to implement the prestress.Several combinations of these methods were compared in this paper and the temperature coefficient of amplification in the cooling method were given ...
