摘要
以无横撑下承式系杆拱桥侧倾稳定问题为背景 ,用能量变分方法导出了其侧倾稳定的近似解析解 ,并通过具体算例 ,比较了由于吊杆的非保向力作用对其侧倾稳定性的影响 。
With the background of lateral stability of non-range-spacer through bowstring arch, analytical approxima-tions are derived in this paper using energy variational approach. Through an example, the effect of force in the hanger on lateral stability is examined. Finally, comparison is made between the method in this paper and common method used in engineering design.
