Abstract
Recently, structural damage detection methods using chaotic excitation have been proposed, where it has been demonstrated that response displacement shows a chaotic behavior by inputting an appropriate chaotic excitation to the structure. This study indicates that the clear difference can be confirmed in the response displacement after damage, and introduces the cross prediction error of the response displacement as a feature to structural health monitoring system using chaotic excitation. The performance and effectiveness of detecting the damage is discussed through numerical simulations. As a result, it is observed that the proposed method can make it possible to judge the structural conditions.
