  • Descrição: Two static load tests on H-piles were conducted in Jacksonville, Illinois to evaluate how well methods for predicting capacity based on driving behavior agree with results from static load tests. The predictive methods included dynamic formulae, WEAP analyses, PDA, and CAPWAP. The pile load test program consisted of dynamically monitoring three test piles during initial driving and at selected re-strike intervals over a three-week period. In addition, re-taps were conducted over several weeks to identify and quantify the effects of time on pile capacity. Two static load tests were conducted on one of the driven piles. Results from the two static load tests are compared with predictions made by several dynamic methods. To determine uniqueness of these load tests, results from the Jacksonville load tests are compared with the results from a database of driven piles (and accompanying static load tests) containing over 100 load tests. It can be seen for the predictive methods investigated and for the EOD and BOR conditions, results from the Jacksonville load tests fall in the middle of the data from both databases. This indicates the load tests conducted at Jacksonville yield typical results, but also provides the reader with a perspective on the range in capacity that may be predicted using these different methods and employing EOD or BOR conditions.
