heal.abstract	A study on the seismic response of massive flexible strip-foundations embedded in layered soils and subjected to seismic excitation is presented. Emphasis is placed on the investigation of the system response with the aid of a boundary element-finite element formulation proper for the treatment of such soil-structure interaction problems. In the formulation, the boundary element method (BEM) is employed to overcome the difficulties that arise from modeling the infinite soil domain, and the finite element method (FEM) is applied to model the embedded massive flexible strip-foundation. The numerical solution for the soil-foundation system is obtained by coupling the FEM with the BEM through compatibility and equilibrium conditions at the soil-foundation and soil layer interfaces. A parametric study is conducted to investigate the effects of foundation stiffness and embedment on the seismic response. (C) 2003 Elsevier Science Ltd. All rights reserved.	en
