峪道河矮塔斜拉桥拉索初张力优化

Extradosed Cable-stayed Bridge Design and Static Calculations

矮塔斜拉桥是一种组合结构体系,其力学性能介于连续梁桥和斜拉桥之间。由于其良好的经济特性和美学效果,近些年在国内外得到了快速发展。对北京峪道河大桥主桥矮塔斜拉桥进行了设计分析,采用MIDAS建立的大桥的空间有限元模型,进行了索力优化和静力计算。

Extradosed cable-stayed bridge are hybrid structures,whose mechanic characteristic lies between continuous beam bridge and cable-stayed bridges. In recent years,extradosed cable-stayed bridges have rapidly developed in the foreign and domestic because of its economy and beauty.An analysis of Yudao River Bridge which is a extradosed cable-stayed bridge is carried out,using MIDAS established finite element model of the bridge and conducted cable force optimization and static calculations.
