| Abstract: | The fault diagnosis of building structure is the basis of construction performing property evaluation. The fault diagnosis of beam is investigated by using the static state testing method. Based on decrease of beam section stiffness, an analysis model of beam is presented. The deflection of beam is chosen as a fundamental variable under a concentrated force. A fault diagnosis method is created through system identification method. Some examples are calculated. The results show the effectiveness of the method presented in this paper. |
| Keywords: | beam deflection fault diagnosis system identification method |
