摘要：
Concrete-Filled Steel Tube (CFST) structures have been widely applied in civil infrastructures. The grouting compactness in the steel tube will seriously influence the loading capacity and structural behavior for the CFST structures. In this paper, the electro-mechanical impedance technique was developed to monitor the grouting compactness of CFST arch bridges. In the study, a small-scale steel tube specimen was fabricated to simulate the actual CFST arch bridge structure, all the experimental results demonstrated that the developed method can clearly reveal the structural changes during the grouting in the steel tube, and can be used to monitor the grouting process and detect the occurrence of debonding disease in real-time.
