摘要
以太原市通达街跨汾河的四跨单塔自锚式悬索桥为背景工程,针对其混合拱塔的结构形式,外壁板为空间曲面且构造复杂等特点,建立主塔的板壳实体有限元模型,对其受力进行分析,总结了变截面混合拱塔的传力特点,为今后同类型结构设计提供依据。
Based on the four-span single pylon self-anchored suspension bridge at Tongda street in Taiyuan city which featured a steel-concrete composite tower and was characterized by a spatial curved surface and a complicated structure,a finite element model was established to investigate the mechanical behavior of the main tower.This paper conducted some analysis and summarized the characteristics of force transfer of the variable cross-section hybrid arch tower,which aimed at providing some reference in the future designs.
