Surface Crack Detection in Prestressed Concrete Cylinder Pipes Using BOTDA Strain Sensors
Structural deterioration after a period of service can induce the failure of prestressed concrete cylinder pipes (PCCPs), with microcracks in the coating leading to the corrosion of the prestressed wires. In this paper, we propose the use of Brillouin optical time-domain analysis (BOTDA) strain sens...
