摘要
在已有方法的基础上,完善了多塔悬索桥的挠度理论及其计算方法,采用影响线加载的方法可方便地得出多塔悬索桥的位移和内力。通过算例表明该方法具有良好的精度,适合于初步设计阶段结构选型时采用。
In this paper, the deflection theory and its calculation method for multi-tower suspension bridges have been perfected on the basis of the existing methods. By the method of loading on the influential lines, the deflection and internal force of the multi-tower suspension bridges can be conveniently calculated. The numerical examples demonstrate that the calculation method as presented herewith is accurate and is applicable to the structural type selection at preliminary design stage.
