Damage system identification of beam system bridge |
| |
Abstract: | Using the result of the static state test, this paper presents a method of beam system bridge structure damage identification, based on system identification theory. A continued beam model with damage is {analyzed}, and satisfaction result is gained. The case shows that the method is convergent and reliable. |
