In this paper, a novel method is proposed for structural damage detection and localization. The key of the proposed method is the use of the response difference transmissibility (RDT) for damage localization. The RDT is defined to relate response differences of the system to be evaluated and those of the original system.
The invariance properties of RDT are also investigated. Based on this, a damage indicator is proposed, and the benefits are verified by a numerical example. Finally, the proposed method is illustrated and validated by finite element simulations and experimental case studies.
