探讨了采用大型有限元分析软件建立预应力混凝土构件分析模型的方法,开展了预应力构件三分点加载至破坏的全过程分析,在考虑混凝土强度等级、钢绞线截面面积和预应力大小三个因素下,对预应力构件极限承载力的影响进行了分析,得出一些有指导意义的结论。%The paper explores the method by adopting the large-scale finite element analysing software to establish the analysis model for the prestressed concrete component,undertakes the whole-process analysis of the prestressed components from the one-third loading to its destruction,analyzes the influence of the factors,including the concrete strength levels,the section coverage of the steel strand and the prestress on the ultimate loading capacity of the prestressed components,and achieves some beneficial conclusions.
