ABSTRACT:
This presentation offers a guided tour through the various ways of accounting for soil-structure
interaction from analysis of the total soil-structure system to analysis of various approximate
models of the system. The focus is on three types of structures, buildings on slab foundations,
tall buildings with several levels of underground parking and bridges on pile foundations.
The study of the effects of slab foundation on input motions to the structure was based on a
comparison between a free field motion and motion recorded on an adjacent foundation slab.
Ninety-nine pairs of such motions were examined. Two thirds showed a reduction in input
motions but the remaining third showed amplified input motions. The latter finding contradicts
the basis of current practice that the slab always reduces the input motions.
