Damage analysis of Reinforced Concrete Beams using Piezoelectric Sensors

Abstract

Identification of crack or damage inside a structure is not possible with traditional methods. In this study piezoelectric sensors are introduced into structure using before placement of concrete and to be in precise sensors act as artificial aggregate. Specimen is taken under three point bending test. A damage characteristic of the beam is studied by using high-voltage pulse emitter, to give a electric signal and recording is made. Extensometer is used to measure the crack and images of the crack should be captured. Final results are plotted in digital image processing to conclude the damage characteristics.
