Abstract

"A static pile load test program was initiated by the Missouri Department of Transportation (MoDOT) to evaluate the use of pile load tests in Missouri LRFD guidelines. The program's approach involves two phases to achieve the appropriate levels of reliability for driven piles in the state of Missouri. This thesis focuses on the data collection efforts of Phase 1. Two quick static pile load tests were performed to failure on test piles in the Southeast Lowlands geologic region of Missouri. The piles were dynamically monitored during installation and subsequent restrike tests performed. The results of the static and dynamic pile testing were evaluated and interpreted. Overall, the nominal resistances predicted by dynamic tests (CAPWAP) at beginning of restrike (BOR) compared well to the results of the static load tests evaluated using Davisson's method (at these specific sites). A comparison of the load transfer distributions from the dynamic and static load tests provided mixed results. The effects of pile set-up after driving are a significant factor to consider in determining the need for a restrike. The additional resistance available following pile setup can have a substantial effect on the nominal resistance determined using dynamic methods. When BOR capacities are measured using dynamic methods they can be used with confidence for the calibration of resistance factors with respective pile types and geologic units. Available pile load test data sets from Missouri's neighboring states and previous efforts conducted in Missouri were compiled as well. Two recently available pile load test databases were evaluated and considered for the upcoming phase to conduct calibration of resistance factors."--Abstract, page iii.
