抄録

The structural damage identification method using genetic algorithm, which estimates the location and severity of inflicted damage by considering natural frequencies and inferred damage patterns has been proposed by the authors. In this paper, the validity of this method is tried by applying it to the estimation of the progress of damage due to cyclic uniaxial loading of a rectangular concrete specimen. At each loading stage, impact sounds and acoustic emissions are measured. By using these as a priori information, the decreased degree of elastic modulus is estimated. By implementing it successively, it is possible to estimate the progress of damage.
