• Abstract:
  Static and dynamic lateral load tests were performed on four full-scale pile groups driven at four different spacings. P-multipliers to account for group ; interaction effects were back-calculated for each test. P-multipliers were found to be a function of row position within the group but were independent of ; position within a row. Curves were developed to define p-mulipliers as a function of pile spacing. Using these p-multipliers along with soil properties ; obtained from site characterization work, excellent agreement between measured and computed response could be obtained. Dynamic load tests were ; performed using the Statnamic load system. Dynamic lateral resistance was consistently higher than the measured static resistance, however, resistance ; was dynamic resistance was greater for the virgin load than for reloading. Simple one degree-of-freedom models were successfully used to interpret the ; static load-deflection curve from the dynamic load-deflection curves. These analyses indicate that the increased dynamic lateral resistance was largely ; due to damping.
