摘要
采用通用有限元ANSYS软件建立了某连续刚构桥的空间有限元计算模型,分析了该桥的动态特性。模型建立时充分考虑了连续刚构桥的特点,采用了实体单元建模,利用杆单元模拟了预应力钢束,对该桥展开动力分析,为该桥桥的设计复核提供了参考。
A finite element model of a continuous rigid frame bridge was established in this paper.The dy-namic characteristics of this bridge were analyzed by ANSYS.Link element was introduced to simulate the prestressed reinforcement in box girder and solid element was used as concrete in the finite element method.Dynamic characteristics analysis of this bridge was performed and some conclusions would offer references for design check of the continuous rigid frame bridge.
