Abstract
Reinforced concrete (RC) structure is the most familiar structure in the field of civil engineering. It is necessary to monitor the health of these RC structures as it undergoes several changes during its life span and as such various techniques are available to do so. Electro-Mechanical Impedance technique (EMI) is a newly invented non-destructive technique which is becoming very popular in the community of Structural Health Monitoring (SHM) in which PZT sensors (surface bonded or embedded) are used as smart materials. These sensors are as such very sensitive and brittle in nature which are available in small dimension (10 mm × 10 mm × 0.2 mm). Due to this reason, these sensors are used in the form of Smart AGgregate (SMAG). This fabricated SMAG is embedded in the monitored structure. This research work focuses on detection of damage of shear deficient-reinforced concrete (RC) Beam before and after strengthening in shear. The Beams were rendered artificially deficient in shear in the form of no shear reinforcement. PZT sensor is used in form of SMAG. The conductance responses were obtained by connecting the SMAG to LCR meter. Further these signatures were used for damage detection and quantification. RMSD index is used for damage quantification. Further loading the specimens under Universal Testing Machine (UTM), damages were given till visible cracks. These induced damages and its severity were identified using EMI Technique.
