摘要
介绍拱梁组合体系桥一类稳定问题,以在建的射阳河桥为研究对象,建立空间有限元模型,对结构进行屈曲分析,计算出各部分构造对体系一类稳定影响,总结出一般性结论,为优化结构设计提供依据。
This paper presents the issues on the first stability of hybrid bridge of arch and beam. With reference to the Sheyang River Bridge being constructed, the spatial finite element models are established to analyze the buckling modes of the structure. The influences of various components of the structure on the first stability are computed, and the general conclusions are drawn, which in all provides the basis for optimizing the design of the structure.
