The dynamic response of the embedded foundations subjected to vertically incident seismic waves is analysed. The soil is modeled by a simple two-dimensional semi-infinite elastic body, and the foundation is represented by a massless rigid strip with a rectangular cross section. The problem is analysed as a boundary value problem, which is formulated in terms of the coupled integral equations. Numerical solutions are finally obtained. The dynamic response of the foundation, expressed as the fraction of the free surface response of the soil, is discussed in relation to the exciting frequency of the incident waves and the depth of embedment of the foundation. ƒL[ƒ[ƒhi‰pjF - ‹LŽ–‹æ•ªF - ‹æ•ª @@@ˆÏˆõ‰ï˜_•¶W
