In this paper, a quantitative relation between the dynamic ground characteristics and the destructiveness of earthquake ground motions for structures is discussed, introducing an intensity measure of a ground motion. The frequency ensemble of the maximum vibrational energy of linear SDOF systems is used as an intensity measure of a ground motion. Artificial strong ground motions are used in the discussion which are based on ground models for various site conditions in the Sendai area, north-eastern Japan. It is concluded that the intensity measure, defined in the above, has close relations both with the integral of the squared transfer function of the ground model and with inelastic responses of elasto-plastic SDOF systems. Also illustrated is the relation between the intensity measure of the artificial strong ground motion and the actual damage ratio of wooden houses in the Sendai area during the 1978 Miyagiken-oki earthquake. キーワード（英）： - 記事区分： - 区分 　　　委員会論文集
