摘要
通过对桁式组合拱桥自振特性的计算分析,提出增加桥梁下弦刚度,减少挖空率的方法,可改善该类桥梁结构动力性能。
By calculating and analyzing the self vibration of trussed combination arch bridge, this paper presents it can improve the dynamic performance of the bridge of this kind by increasing the bottom chord stiffness of bridge and reducing its hollowed out rate.
