A review of the literature is presented on the axial capacity of deep foundations subjected to repeated loads. Data are summarized on anchors, driven piles, and drilled shafts. In general, the behavior is similar for the three foundation types. Guidance is given for predicting the capacity and displacement of deep foundations under these loading conditions. Because of the limited data available, research that is needed to advance the state of knowledge on the subject has been identified.
