摘要
简述三塔斜拉桥和三塔悬索桥的静力特性,提出三塔斜拉—悬索协作体系桥梁,用ANSYS软件对三塔缆索承重桥梁各体系建立三维有限元模型,分析比较各体系的静力特性及讨论中塔纵向刚度对各体系结构性能的影响。
Static performance of three-tower cable-stayed bridges and three-tower suspension bridges is summarized. Three-tower caNe-stayed and suspension composite bridges is proposed. The 3-D finite element model of three sorts of the three-tower cable supported bridges are estab- lished with the ANSYS software. In this paper, the static performance of three sorts of cable supported bridges is analyzed and compared, and the effect of mid-pylon longitudinal stiffness on the structural performance is discussed.
