Abstract
Nonbuilding structures located on soft soils are commonly supported on deep foundations consisting of a group of piles and a large pile cap embedded in the soil. The weight of the pile cap is often neglected in the seismic analysis of this system on the assumption that the inertia forces due to the pile cap can be directly transferred to the soil surrounding the sides of the cap. This paper provides an evaluation of conditions under which this assumption is valid and identifies the conditions when it would not be valid. Soil type, pile cap mass, passive pressure, side friction, backfill compaction, and pile resistance are addressed as contributing factors. A procedure for evaluating the amount of soil resistance acting on the sides of the pile cap under seismic loading was developed for this evaluation.
