| 摘 要： | 自振频率、振型等是反映桥梁结构动力特性的模态参数,是评价桥梁动力性能的重要依据。以某轻轨连续刚构为例,采用大型桥梁专业分析软件MIDAS建立该桥的有限元计算模型,对其进行模态分析,得出相关模态参数,其计算结果可供桥梁设计和成桥检测时参考。 |

| Abstract: | Natural frequency and form of vibration are modal parameters reflecting dynamic behavior of bridge structure,they are critical bases to evaluate the dynamic performance of bridges.This paper takes a certain light rail continuous rigid frame bridge as an example,a finite element computing model is set up for this bridge by adopting large bridge analysis software MIDAS,so to carry out modal analysis and get relevant modal parameters,the results may be used as reference in bridge design and as-built inspection. |
| Keywords: | light rail continuous rigid frame bridge dynamic behavior modal analysis |
