It is very difficult to judge for structures damaged by the low cycle fatigue during earthquake to be able to use or not in future, or to estimate how to reinforce them. Therefore, the health monitoring system in service to monitor the damage rate of building by the low cycle fatigue is proposed to assure the safety of the buildings. In this paper, the using of the wavelet transform is proposed to extract the fatigue signals from the noisy detected signals. The model of fatigue is considered to be the reducing stiffness of structural members having impulse forces occured at random intervals. The response of model structure excited by these impulse forces is analyzed under noisy condition. The wavelet transform is applied to the analyzed responses and it is proved to be able to extract the assumed signals of fatigue from this responses. キーワード（英）： - 記事区分： - 区分 　　　委員会論文集
