摘要
阐述了在用有限元方法分析张弦梁结构的预应力张拉过程时,常用的施加预应力的方法有力模拟法、等效降温法和初应变法,分析了这三种方法的优缺点,并讨论了三种方法的适用范围,以使三种有限元模拟方法均能较准确地模拟张弦梁施工的预应力张拉过程。
Three methods, force method, equivalent decreasing temperature method and initial strain method are often used to simulate the prestressing force tension procedure of BSS, the paper analyses their merits and weaknesses and demonstrates their applicable scope.
