This study proposes an index for prediction of damage to wooden houses, RC structures, pipeline, and so on. Since the structures are affected by a fatigue damage, it is inevitable in predicting damage to structures to consider the number of seismic response cycles of the large seismic response. In this study, an index for predicting damage to wooden houses is proposed in taking account of number of seismic response cycles and the natural period of structures. This index, which is called as 'Fatigue response Spectral Intensity (FSI value)', is defined as integrated value on tripartite coordinates ; natural period of wooden houses, pseudo-response velocity spectra and the number of seismic response cycles. In addition, existing probability of natural period of wooden houses is taking into account in this index.This FSI value was calculated by using the data in the recent earthquakes in Japan and worldwide such as the 1994 Hokkaido Toho-oki earthquake, the 1994 Sanriku Haruka-oki earthquake, the 1995 Hyogoken-Nambu earthquake, 1997 Kagoshimaken-Hokuseibu earthquake, 1999 Taiwan Ji-Ji earthquake and so on. This index was able to represent the damage to wooden houses more accurately than the alternative indices such as maximum acceleration and S1 value.

本研究提出了一种预测木结构房屋、钢筋混凝土结构、管道等灾害的指标。由于结构受到疲劳损伤的影响，在预测结构损伤时不可避免地要考虑大地震反应的地震反应周期数。本文提出了一种考虑地震反应周期数和结构自然周期的木结构房屋损伤预测指标。该指标称为“疲劳响应谱强度（FSI值）”，定义为在三方坐标上的积分值；木制房屋的自然周期、伪反应速度谱和地震反应周期数。此外，该指标还考虑了木结构房屋自然年限的存在概率。本文利用1994年北海道东崎地震、1994年三陆原崎地震、1995年小谷根-南部地震、1997年鹿古岛根-北武地震、1999年台湾集集地震等近年来日本和世界范围内地震的资料计算了FSI值。该指标比最大加速度和S1值等替代指标更能准确地反映木质房屋的损坏情况。
