Abstract
Active structural health monitoring of reinforced concrete civil engineering structures using piezoceramic smart aggregates represent nondestructive evaluation techniques which is characterized by high reliability, wide frequency range, low cost, ease of use, and multifunctionality. Procedure of damage detection is based on wave propagation and used basic piezoelectric effects for smart aggregate actuators and sensors. Represented active monitoring method can detect damage that is not visible with the naked eye, damage that is in inaccessible parts of structures, and damage that cannot be caught by visual inspections. Also, during the measurement, a construction can be undisturbed used which is very important for bridges or industrial production halls. Structural health monitoring is performed by a one-dimensional and two-dimensional damage index formed using wavelet signal analysis and based on energy changes of output sensor signals. In this paper, piezoelectric smart aggregates for structural health monitoring, damage detection, and localization purpose of reinforced concrete civil engineering structures are represented.
