本研究では 2018年，2019年に発生したM6クラスの地殻内地震の地震観測記録を用いて，木造建物の最大応答変形角の予測式を求めた．まず，各対象地震に対して，性能等価加速度応答スペクトルと観測記録から計算した加速度応答スペクトルによって木造建物の最大応答変形角を評価し，実被害との対応を考察した．次に震源特性，伝播経路特性，地盤増幅特性を考慮し，表層30mの平均S波速度をパラメータとする最大応答変形角の予測式を求めた．予測式を求めた結果，最大応答変形角の観測値と予測値の相関係数は0.7～0.9という，良好な値となった．
In this study, the maximum response deformation angle of wooden building was evaluated using earthquake observation records of M6 class crustal earthquakes that occurred in 2018 and 2019, and the evaluation formula of the maximum response deformation angle of the wooden building was obtained.. First, for each target earthquake, the maximum response deformation angle of the wooden building was evaluated from the performance equivalent acceleration response spectrum and the acceleration response spectrum calculated from the observation records, and the correspondence with the actual damage was considered. Next, evaluation formula for the maximum response deformation angle using the average S-wave velocity at the surface layer of 30 m was obtained in consideration of the source effect, path effect, and site effect. As a result of obtaining the evaluation formula, the correlation coefficient between the observed value of the maximum response deformation angle and the predicted value was a good value of 0.7-0.9.
