Comparative Analysis of Two Damage Detection Methods in Early Warning System of Bridge Safety

摘要：

Damage detection technology is a key content of the early warning system of bridge safety. In this paper, based on the simulation analysis of continuous box Girder Bridge, comparative analysis of curvature mode method and flexibility matrix method is studied on three aspects of sensitivity on damage detection, accuracy on detection and localization and anti-influence of test error. The studies of applicability of these two methods to the damage detection of bridge provide a basis for the selection of damage detection method for the early warning system of bridge safety.
