Abstract
For the numerical simulation of dynamic soil-structure interaction problems both a frequency and a time domain formulation are presented. In order to be capable to consider more sophisticated models of the structure, the frequency domain algorithms for homogeneous and layered halfspaces have been coupled to the Finite Element Program ANSYS. Flexibility functions are presented for a concrete slab track system. Furthermore the stress distribution in the subsoil is calculated and visualized. The time domain formulation is applied for demonstrating the basic phenomena of a moving load passing by with sub- and supercritical speed. Besides that, a nonlinear, tension-free condition of contact between the track and the subsoil is mentioned briefly.
