Two methods are developed for the calculation of the dynamic response of a group of rigid structures. One is the application of a computationally efficient boundary element method. This procedure is based upon subdividing the contact area into a number of smaller triangular sub-regions, and the contact tractions and the Green's functions are assumed to be linearly varying functions of space coordinate within each sub-region. The obtained system of integral equations is discretized and reduced to a system of linear algebraic equations. The other is a much simpler method than the first one, and it is for obtaining a first order approximation. For this method only the response of a isolated structure and the Green's functions for the elastic half-space are needed. Numerical results for two cylindrical masses (Fig.2) are presented when they are excited by vertically incident plane waves. The amplitude ratio of the motion of the structure to that of the corresponding isolated structure is plotted in Fig.6 as functions of dimensionless frequency for different values of separation. A comparison of the four sets of curves of Fig.6 makes it evident that the effect of varying the mass of the structure, mc, on such a ratio is not so significant as the mass of the second structure, ma, and that the agreement between the results of the proposed two methods is reasonably good., rights: 社団法人日本建築学会 rights: 本文データは学協会の許諾に基づきCiNiiから複製したものである relation: IsVersionOf: http://ci.nii.ac.jp/naid/110004085961/, text, application/pdf}, pages = {121--130}, title = {弾性地盤上の隣接剛体構造物の動的相互作用}, year = {1988}, yomi = {カワカミ, ヒデジ} }
