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。
Based on the finite element method, taking the Wei-dimensional Yangtze River Bridge as an example, a computational model of space power is established. Consider two different types of structure, and then calculate and analyze the dynamic characteristics.
