The bearing plate is an important part of a tendon–anchorage subsystem; however, its function and safety can be compromised by factors such as fatigue corrosion. This paper explores the feasibility electromechanical impedance (EMI) technique for crack detection in prestressed anchorage. Firstly, theory EMI presented. Next, well-established anchorage literature selected target structure. Thirdly, 3D finite element model PZT transducer–target subsystem simulated, consisting concrete segment,...
The smart strand technique has been recently developed as a cost-effective prestress load monitoring solution for post-tensioned engineering systems. Nonetheless, during its lifetime under various operational and environmental conditions, the sensing element of potential to fail, threatening functionality resulting in inaccurate estimation. This study analyzes effect failures on impedance characteristics develops 1D convolutional neural network (1D CNN) automated fault diagnosis. Instead...
This study examined the feasibility of admittance-based method for detecting simulated damage in bearing plate a prestressed anchorage. The proposed utilized PZT (lead zirconate titanate) interface technique to acquire strong admittance response from Firstly, numerical was demonstrated by presence fatigue cracks and preload changes fixed–fixed beam-like structure. Next, experimental verification carried out using lab-scale anchorage model. A prototype designed surface-mounted on plate....
