摘要
为配合大跨度悬索桥的设计,采用悬索桥挠度理论的实用计算方法,提出了通过初拟结构尺寸———挠度理论分析———改进和优化截面尺寸的反复计算来确定悬索桥各部分结构尺寸的计算方法。算例分析表明:用本方法得到的结构有关数据与实际设计情况比较吻合。
In order to perform the structural design of suspension bridges,a structural design method based on the practical calculating method of the deflection theory is described in this paper. Structural dimensions of suspension bridges can be determined by this method.Through the analysis of the example,it is showed that the structural dimensions determined by this method are in good accordance with the practical design structural dimensions.
