| 摘要： | In steel concrete composite structures, the presence of interface debonding damages critically threaten structural integrity, posing significant concerns to safety, serviceablity and durability. Monitoring and detecting such internal interfacial damages throughout a structure’s service lifespan is of significant practical importance. While non-destructive testing (NDT) methods are essential for this purpose, conventional NDT techniques, including radiography and magnetic particle testing, possess inherent limitations. This paper introduces a novel interfacial debonding detection technique based on the centroid frequency shift theory. Experimental validation conducted by authors substantiates its precision in identifying debonding regions. Additionally, the proposed piezoelectric sensor module demonstrates strong engineering applicability. This innovation holds significant promise in ensuring the integrity and safety of steel-concrete composite structures. |
