Abstract

Coda wave interferometry is an ultrasound-based technology for structural health monitoring of concrete structures that is based on a correlation evaluation of two ultrasonic signals. To detect damage locations, sensitivities of the coda waves are used. These sensitivities are derived from wave propagation approximations that are computed with the finite element method applied on a diffusion problem. So far, the actual value of localized damage has little meaning in real experiments. This study compares results from strucutral analysis to the actual measurements. The analysis results should be used as the basis of a measurement classification that in the end should identify damage with a threshold. The comparison is performed at a real four-point bending test of a reinforced concrete specimen.
