| Abstract: | The self-vibration（natural frequency and mode type）of the concrete filled steel tube component is an important parameter for dynamic characteristics analysis and seismic design.Based on the analytical theory of self-vibration,the article uses finite element model to perform stimulation analysis on the natural frequency and model type of the con-crete filled steel tube component,and discusses their applications in the bridge damage de-tection. |
| Keywords: | Concrete filled steel tube Self-vibration characteristics Analysis |
