摘要
本文以某大桥为例，用MIDAS大型有限元软件计算了该大桥200 m跨钢管混凝土拱桥的自振频率和振型，用软件对中承式钢管混凝土拱桥动力特性进行了计算和分析。
This paper, taking a bridge as an example, using MIDAS finite element software to calculate the natural vibr- ation frequencies and modes of half-through arch bridge of concrete and steel tubes with 200 m-span, calculating and anal- yzing the dynamic characteristics of arch bridge of concrete filed steel tubes by software.
