摘 要: 回顾了三种分析大跨度拱桥极限承载力的方法 ;以上海在建的主跨 5 5 0 m的中承式钢拱桥为例 ,运用大型有限元分析软件 ANSYS对该桥的极限承载力进行了参数分析与比较 。 Three methods of analysis for the ultimate capacity of long span bridges are reviewed. The example bridge is a long span half through steel arch bridge of a 550 m central span length under construction in China. The ultimate capacity of this bridge is investigated.The effects of different parameters on the ultimate capacity of the bridge have been studied.
