Abstract
A hybrid boundary element / finite element method (BEM/FEM) is developed for dynamic inelastic soil-structure interaction under conditions of plane strain. The time domain FEM is used to model the structure, as well as the part of the soil surrounding the structure, which is expected to behave inelastically, while the time domain elastodynamic BEM is used to model the remaining part of the soil extending to infinity, which is expected to behave elastically during the motion. The two methods are coupled together through equilibrium and compatibility at their interface. A special step-by-step time integration algorithm is developed which provides an accurate time history of the response. A numerical example involving seismic waves and Drucker-Prager elastoplastic soil is used to illustrate the method.
