Abstract
The conventional direct frequency or time domain boundary element method as applied to dynamic soil-structure interaction analysis is discussed. Both the structure and the soil are assumed to be homogeneous, isotropic and linear elastic or viscoelastic bodies under two - or three - dimensional conditions. The dynamic disturbances may be externally applied loads or seismic waves of an arbitrary spatial and temporal variation. The effects of inhomogeneity and anisotropy of soil on the system response are also considered. Applications including the dynamics of foundations and above ground structures and the dynamic response of underground structures are described in detail. The general conclusion is that the boundary element method alone, or coupled with the finite element method, is ideally suited for dynamic soil-structure interaction problems from both the accuracy and efficiency viewpoints.
