| 摘 要： | 应用通用有限元软件ANSYS对预应力钢筋混凝土梁的非线性性能进行了数值模拟，并讨论了钢筋和混凝土的本构方程、破坏准则、预应力施加和收敛准则等问题，对该梁在预应力条件下、没有施加预应力但受荷载作用、施加了预应力并受荷载作用这三种工况下所得的数值模拟挠度解作了分析；同时将荷载作用下的该预应力混凝土梁的有限元模型挠度解与按结构规范计算的挠度结果作了比较，指出利用ANSYS对预应力钢筋混凝土作有限元分析是可行的。

| Abstract: | In this paper, FLM software of ANSYS was used to simulate the nonlinear capability of prestressed reinforced concrete beam. and discussed the problems include the infliction of prestressing force;convergent criterion etc.At last,the three result of deflection is analyzed with this beam under the condition of prestressed and nonprestressing force with the load; at the same time, the result deflection of the prestressed reinforced concrete beam under the condition of the load was compared with the deflection of this beam according to configuration criterion calculating result. |
