TRANSIENT-RESPONSE OF MULTIPLE RIGID FOUNDATIONS ON AN ELASTIC, HOMOGENEOUS HALF-SPACE

Three-dimensional transient response of both massless and massive mult iple, rigid foundations, bonded to an elastic, homogeneous half-space, is investigated to study the effect of dynamic interaction through-so il. The numerical procedure is formulated in terms of the boundary ele ment approach by means of the transient fundamental solutions develope d by the authors (1994). This procedure works efficiently for the prob lem addressed here since the separated foundations are analyzed withou t discretizing the surface of the half-space outside the contact areas between the half-space and the foundations. It also provides the poss ibility to study nonlinear problems involved with semi-infinite soils.
