摘要
根据理想完善结构假定的第一类稳定理论,结合结构力学和运用能量法推导出双肋外斜式下承式系杆拱桥的侧倾稳定极限荷载的一般公式,并通过有限元软件验证计算公式的正确性,为该类桥梁结构设计提供了简便的分析计算方法。
According to the ideal perfect structure assumed the first stability theory, combined with structural mechanics and use of energy method derived the general formula of the double rib outer inclined supporting tied arch bridge roll stability limit load, and verify the calculation by finite element software, and through finite element software verified the correctness of this calculation formula, provided simple and convenient calcula- tion method for the bridge structural design.
