| Abstract: | 6Taking the environmental vibration test on one flexible bridge tower structure as example,the article discusses the general procedure and technical detail of this test and also per-forms recognition analysis on bridge tower dynamic characteristics(vibration model index) by using random sub space identification(SSI).It shows that the analysis result is almost identical to the theoretical value. |
