Abstract:

The effects of local soil conditions on the characteristics of earthquake motions (soil amplification) and on the dynamic response of structures for a given foundation type (soil structure interaction) have been studied extensively. The effects of seismic shaking on soil properties including cyclic degradation, pore pressure buildup and possible liquefaction have also received considerable attention. Little work has been done, however, on the assessment of possible damage to a foundation during an earthquake (short of collapse) or the evaluation of the foundation's condition after an earthquake. Rules and procedures to inspect, retrofit and/or upgrade existing foundations are needed for a complete assessment of the seismic vulnerability of buildings.
