Abstract

Recently, extension of the active use life span of infrastructures has been a big problem in all over the world. In usually, the inspection and judgment of damage level of structures are mostly carried out by expertise professional engineer. Therefore, it is required to establish the useful health monitoring system for the judgment and diagnosis of structural damage level and its position. In this study, the damage identification health monitoring system by using piezoelectric element is produced. The fundamental examinations are performed from the observation of wave motion and Fourier spectrum of the monitoring data. The possibility of effects and application for real structures of the methods in this study is discussed from these results.
