摘要
东莞大汾北水道桥为主跨128m的下承式钢管混凝土刚架系杆拱.本文以该桥为分析对象,建立了全桥空间有限元计算模型,对结构进行静力分析和动力特性分析,着重进行了结构弹性一类稳定与抗震性能分析,以为此类桥型设计提供参考.
The Dongwan Shuidao Bridge is a concrete filled steel tubular (CFST) tied rigid frame through arch bridge with a main span of 128?m. In this paper, a space FE model is developed to analyze its static and dynamic behavior with an emphasis on analyses of elastic buckling and the seismic performance. It can provide the design of such type bridge with reference.
