摘要
以2×85m跨度桥梁为例,运用Midas/civil有限元软件建立相同跨度的矮塔斜拉桥、连续刚构桥及传统斜拉桥空间梁单元模型,研究这3种桥梁形式动力性能的相似性及差异性,通过对比,凸显矮塔斜拉桥的动力性能特点。
Taking a two-span(2x85m) bridge as an example,in this paper the finite element software Midas/civil is used to establish the three-dimensional beam element models of the same span of an extradosed cable-stayed bridge,a continuous rigid frame bridge and a traditional cable-stayed bridge.The similarities and differences of the dynamic performance of the three kinds of bridge are studied.Through these comparisons,the characteristics of the dynamic performance of extradosed cable-stayed bridge is highlighted.
