Vibrational characteristics and earthquake responses of the cross-interaction system between two cylindrical building structures embedded in a viscoelastic soil stratum are presented in this paper. The three-dimensional space model of the soil ground are assumed to be subdivided by several horizontal planes. A formulation for such a cross-interaction system may be obtained by making use of the closed-form solution based on the exact displacement functions in the horizontal direction and by the finite element technique in the vertical direction. Using the cylindrical coordinates, the exact solution can be expanded by infinite series in the case of cross-interaction between two foundations with the same circular cross-section. In order to analyze the transient coupled responses of the two building structures due to an impulsive or a typical earthquake excitation, fast Fourier transformation technique is used. The mutual effects of the adjacent building structures on their vibrational characteristics and transient responses are discussed in detail. キーワード（英）： - 記事区分： - 区分 　　　委員会論文集
