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.
