摘要
以高效预应力混凝土T型梁受力试验成果为基础,采用考虑材料非线性的有限元方法,选取适当的材料本构关系和计算模型,对试验梁进行了受力全过程仿真计算分析,通过有限元分析和试验数据的结果对比,探讨ANSYS数值模型分析预应力混凝土结构变形性能的可行性,为实现预应力混凝土结构的"虚拟试验"提供了依据。
On the basis of the experiments of loading behaviors of the high efficiently prestressed concrete T-beam and the nonlinear characteristic of materials,an appropriate material constitutive relationship and a calculation model were selected,the behavior over loading process of the T-beam was simulated and analyzed by ANSYS.Comparison with the results of the finite element analysis and experiments,it is concluded that the simulation of deformation performance of the high efficiently prestressed concrete structures is feasible by the ANSYS.The result can provide the basis for the virtual test of prestressed concrete structure.
