Steel-concrete-steel (SCS) sandwich structures have important advantages over conventional concretestructures, however, bond-slip between the steel plate and concrete may lead to a loss of compositeaction, resulting in a reduction of stiffness and fatigue life of SCS sandwich structures. Due to theinaccessibility and invisibility of the interface, the interfacial performance monitoring and debondingdetection using traditional measurement methods, such as relative displacement between the steel plateand core concrete, have proved challenging. In this work, two methods using piezoelectric transducersare proposed to detect the bond-slip between steel plate and core concrete during the test of the beam. The first one is acoustic emission (AE) method, which can detect the dynamic process of bond-slip. AEsignals can be detected when initial micro cracks form and indicate the damage severity, types andlocations. The second is electromechanical impedance (EMI) method, which can be used to evaluate thedamage due to bond-slip through comparing with the reference data in static state, even if the bond-slipis invisible and suspends. In this work, the experiment is implemented to demonstrate the bond-slipmonitoring using above methods. Experimental results and further analysis show the validity andunique advantage of the proposed methods.
