Abstract:

Spread footings are most often less expensive than deep foundations. In an effort to improve the reliability of spread footings, this research project was undertaken. The results consist of: (1) a user friendly microcomputer data base of spread footings, case histories and load tests; (2) the performance of five large scale square footings in sand; (3) an evaluation of the current accuracy of settlement and bearing capacity prediction methods; (4) observations on the scale effect, the zone of influence, the creep settlement, and soil heterogeneity; (5) a new and simple method to predict the complete load settlement curve for a footing as well as several correlations; and (6) evaluation of the WAK test, a dynamic test for spread footings.
