The computer program SASSIG (a System for Analysis of Soil-Structure Interaction using Green’s functions) allows the dynamic analysis of soil-structure interaction including soil-pile interaction as well as the simulation of wave propagation due to moving loads.

SASSIG was coded by Dr. Julio Garcia at the Ruhr University Bochum, Germany, as an enhanced version of the computer program SASSI (a System for Analysis of Soil-Structure Interaction), which was developed at the University of California, Berkeley, by a research team under the direction of the late Professor John Lysmer. SASSI has been the state-of-practice tool regarding dynamic soil-structure interaction analysis.

New computational modules have been implemented in SASSI including:

·        explicit formulations to compute complex displacements for unit dynamic loads in the interior of a layered medium proposed by Kausel & Peek, which allows to simulate pile foundations, and

·        a superposition scheme in time and space, which allows to simulate wave propagation phenomena due to moving loads.

The result is the system of computer programs SASSIG.
