| Abstract: | In order to give a proper assessment to the active duty bridge and recognize the situation of damage appears. This article optimizes the sensor placement based on the study of effective independ- ence method, and use the flexibility difference method to simulate the damage detection. Finally, the effectiveness of this method is verified by an example. |
