| 摘 要： | 组合截面桥梁结构包括分层浇注混凝土结构桥梁以及钢混凝土组合结构桥梁等。近年来这类桥梁结构的工程应用越来越多,而这类桥梁结构的分析计算是一个比较复杂的工程计算问题。本文采用刚臂节点位移协调方法,用多个梁单元来模拟组合截面,建立组合截面桥梁结构施工全过程分析方法,并给出对比分析算例。

| Abstract: | Cosection bridge structure includes layered cast concrete bridge structure and steelconcrete composite beam bridge structure.In recently years, this type bridge used more and more in construction.It is complicated in engineering calculation for this type bridge construction analysis. In this paper, the bridge construction analysis model of rigid arm synchronal displacement and one cosection beam element modeled by several beam elements in the same position is introduced and some comparative analysis examples will be offered. |
