Abstract
A rigorous computational procedure for the analysis of soil-flexible foundation-structure interaction is developed based on the finite element method. A model of the soil medium is constructed using the ACS SASSI platform and the discrete (in space), frequency dependent, impedance matrix of the system is obtained. The special purpose finite element program ACS SASSI takes into consideration the infinite extent of the soil medium by means of special energy absorbing boundaries. In addition to the above discrete impedance matrix, a complete set of simplified, continuous in space and frequency independent impedance functions are also presented in non-dimensional form. The above impedance matrices are used in a straightforward manner, in conjunction with specialized, e.g. ACS SASSI, or general purpose, e.g. ANSYS, FEM simulation platforms, for the frequency or time domain dynamic/seismic analysis of structures resting on flexible mat foundations.
