Taking prestressed reinforcement as a part of structure,the equivalent nodal load was obtained to calculate the effect of tensioning bars. A three-parameter viscoelasticity model was adopted to simulate the concrete creep.
根据其结构及受力特点,提出用实体退化单元建立P.C.连续刚构桥施工过程分析的三维模型;将预应力筋作为结构的一部分,用等效节点荷载模拟预应力的张拉效应;用三参数粘弹性模型模拟混凝土徐变效应;提出了阶段模型应力的处理方法。
