A research program to study the behavior of piles and pile groups subjected to cyclic lateral loading was conducted at a Houston, Texas site. A single pile and a nine-pile group situated in the natural clay were tested and then the upper several feet of clay were removed and replaced with sand and the tests were repeated. Following these tests, another study was undertaken to measure experimentally pile-head flexibility reduction interaction factors for the pile group in sand. Tests were made cyclically at varying magnitudes of applied groundline shear on single piles and two-pile and three-pile subgroups, and the response of unloaded piles in the group was measured. Concurrent with these studies, pressuremeter PMT and cone penetrometer CPT tests were performed in both the clay and the sand from which capacity predictions were made. Each of these studies generated a report with voluminous data. This report summarizes the major findings into one volume.
