bridge damage localization differential curvature displacement self-vibration frequency robustness
Authors deeply investigated the application of differential curvature difference indicator in damage localization of bridges. Based on the foundational theory analysis, the practical and detailed application method of this indicator was proposed. The effectiveness of differential curvature difference was verified in multiple damage localizations of bridges by a cable-stayed bridge example. The comparative advantage with respect to the previous mode method was assessed. Finally, some valuable suggestions for improving its robustness were also proposed. Results show that the method has certain advantages.
