Astani Dept Seminar: The Effect of Soil-Structure Interaction on Seismic Response of Buildings

A Seminar on " The Effect of Soil-Structure Interaction on
Seismic Response of Buildings " by Dr. Mohammad Ali Ghannad, Associate
Professor, Dept. of Civil Engineering, Sharif University of Technology,
Tehran, Iran


It is well known that the flexibility of soil beneath the structure affects
its seismic response due to Soil-Structure Interaction (SSI). SSI not only
affects the elastic response of structures, but also their inelastic
behavior during earthquakes. This subject has been studied by numerous
researchers and a wealth of knowledge is currently available in the
literature.
In this presentation, a brief summary of recent research done on the subject
at Department of Civil Engineering of Sharif University of Technology is
presented. The main focus is the parametric study on SSI effect on global
inelastic response of structures. This is done by employing a rather simple
model for the soil and structure to study the effect on structural strength
and ductility demands. Some aspects of current US provisions for introducing
SSI in practical design of structures are also discussed.
