The maximum earthquake motions on the ground, the dynamic characteristics of soil-layers in the range of short period reflecting the shallow soil-layers on a small area are investigated, taking Sendai district damaged by the Off-Miyagi Prefecture Earthquake of June, 1978 as an example. The modeling of ground characteristics in the short period range is performed based on the results of the analytical investigation of the elastic and inelastic system as well as microtremor measurements, boring data and penetration tests. In order to estimate the earthquake motions on the ground surface, the observed strong motion at the Sendai Sumitomo Building are analyzed with consideration of building-subsoil interaction to get the incident wave at the structural base rock. In order to establish an appropriate seismic microzoning method with particular attention to the mathematical modeling, the predominant periods, magnification factors, maximum accelerations on the ground surface and the ductility factors of super-structure are computed. The comparison of such seismic microzoning maps with the extents of real damages to buildings is carried out. The correlation between them is satisfactory. キーワード（英）： - 記事区分： - 区分 　　　委員会論文集
