• Abstract:
  In response to the mandate on Load and Resistance Factor Design (LRFD) implementations by the Federal Highway Administration ; (FHWA) on all new bridge projects initiated after October 1, 2007, the Iowa Highway Research Board (IHRB) sponsored these research ; projects to develop regional LRFD recommendations. ; The LRFD development was performed using the Iowa Department of Transportation (DOT) Pile Load Test database (PILOT). To ; increase the data points for LRFD development, develop LRFD recommendations for dynamic methods, and validate the results of ; LRFD calibration, 10 full-scale field tests on the most commonly used steel H-piles (e.g., HP 10 x 42) were conducted throughout Iowa. ; Detailed in situ soil investigations were carried out, push-in pressure cells were installed, and laboratory soil tests were performed. Pile ; responses during driving, at the end of driving (EOD), and at re-strikes were monitored using the Pile Driving Analyzer (PDA), ; following with the CAse Pile Wave Analysis Program (CAPWAP) analysis. The hammer blow counts were recorded for Wave Equation ; Analysis Program (WEAP) and dynamic formulas. ; Static load tests (SLTs) were performed and the pile capacities were determined based on the Davisson’s criteria. The extensive ; experimental research studies generated important data for analytical and computational investigations. The SLT measured loaddisplacements ; were compared with the simulated results obtained using a model of the TZPILE program and using the modified ; borehole shear test method. Two analytical pile setup quantification methods, in terms of soil properties, were developed and validated. ; A new calibration procedure was developed to incorporate pile setup into LRFD.
