| Abstract: | Natural frequencies are modal parameters that reflect dynamic behavior of bridge structures and they are critical bases to evaluate the dynamic performance of bridges. This paper takes a large continuous rigid frame bridge as an example and a finite element computing model is set up for this bridge based on software MIDAS, which is to carry out modal analysis and get relevant modal parameters. The results can be used as reference in bridge inspec- tion. |
