This paper treats response analysis in the time domain of a structural system with eccentricity on a foundation embedded into an elastic half-space to the horizontally propagating seismic waves. Mathematical model for analysis is composed of a single-story structure with three degrees-of-freedom (two horizontal components and torsion) and a soil-foundation system with five degrees-of-freedom (two horizontal components, two rocking component and torsion). Stiffness and damping matrices of the soil-foundation system is represented numerically from compliance matrix of a foundation embedded into a half-space, which is derived by use of the boundary element method under the relaxed boundary condition. Horizontal and torsional excitations to the foundation are evaluated by integration of acceleration wave of two strong motion earthquakes for the foundation volume. Maximum translation, rocking and torsion response of the soil-structure system are compared for variation of shear wave velocity of soil, depth of embedment of foundation, natural period for translation or torsion and eccentricity of upper structure. From the results of analysis, it is noticed that effects of embedment depth of foundation on translation and torsion response of upper structure are small. And the influence of eccentricity of upper structure on torsion of itself is represented decrease with softness of soil, though it increases with eccentricity for hard soil. キーワード（英）： - 記事区分： - 区分 　　　委員会論文集
