摘要
介绍了同时考虑材料非线性和几何非线性的钢管混凝土拱桥稳定性分析方法,采用该方法对巫峡长江大桥的极限承载力进行了分析。研究了恒载作用下主拱的破坏路径,并讨论了不同的布载方式与风荷载对于结构极限承载力的影响。
The paper presents the analysis of stability for a concrete-filled steel tubular arch-bridge which simultaneously takes the geometrical nonlinearity and material nonlinearity into consideration,and the Wuxia Bridge has been proposed by the method. The failure process under the dead load is examined in the study. Finally, the effects of different load distributions and wind loads on the ultimate load-carrying capacity of the bridge are investigated.
