摘要
根据特征值屈曲分析方法,对某下承式钢箱系杆拱桥的稳定性进行分析计算。分析一阶失稳形态和稳定系数的计算结果,探讨了横撑数量、样式、布置对稳定性的影响,并从理论上给予了解释。
Throgh eigenvalue buckling analyses, the stability of the through steel-box tie-bar arch-bridge is analyzed. The normal unstable modalities and stability factors axe described. The effect of the transverse brace number, shape and arrangement are described as well,which are analyzed theoretically.
