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.

这项研究提出了预测木屋，RC结构，管道等损坏的指数。由于结构受到疲劳损害的影响，因此不可避免地预测结构的损害，以考虑大型地震反应的地震反应循环的数量。在这项研究中，提出了一种用于预测木制房屋损坏的指数，以考虑到地震反应周期的数量和结构的自然时期。该指数称为“疲劳响应光谱强度（FSI值）”，被定义为三方坐标上的集成值。木制房屋的自然时期，伪响应速度光谱和地震反应周期的数量。 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台湾Ji-ji地震等。该指数能够比最大加速度和S1值等替代指数更准确地表示对木制房屋的损害。
