摘要
基于有限元方法,以地维长江大桥为例,建立空间动力计算模型。考虑2种不同的结构形式,然后进行动力特性计算和分析。
On the basis of the method of finite element, Diwei Yangtze River bridge in Chongqing City is taken as an example to establish space dynamic calculating models. Two different structure shapes are taken into account, then the calculation and the analysis of its dynamic characteristics are carried out.
