14Chapter 1 – Introduction: An overview of the current bridge pile foundations, thepile foundation design philosophies, and the driven pile foundation design andverification methods. Current state of knowledge pertinent to pile foundations. Briefdescriptions of problem statement, research scope and objectives, and research tasks.Chapter 2 – Literature Review: Description of the history and theory of dynamicanalysis methods. Summary of past reliability studies of dynamic analysis methodsreported by other researchers. Detailed discussion of LRFD calibration methods andpile setup.Chapter 3 – Pile Setup in Cohesive Soil with Emphasis on LRFD-An ExperimentalInvestigation: Detailed description of the pile driving, restriking, dynamic testing,and static load testing procedures on test piles performed in Iowa. Full description ofthe in-situ and laboratory soil tests and results. Evidence of pile setup and itsqualitative correlation with surrounding soil properties were presented.Chapter 4 – Pile Setup in Cohesive Soil with Emphasis on LRFD-AnalyticalQuantifications and Design Recommendations: Pile setup investigation usingdynamic analysis methods. Development, validation, and application of proposed pilesetup prediction methods.Chapter 5 – A Procedure for Incorporating Pile Setup in Load and ResistanceFactor Design of Steel H-Piles in Cohesive Soil: Development of a new calibrationprocedure using First Order Second Moment (FOSM) reliability method to separatelyaccount for the uncertainties associated with initial pile resistance at EOD and pilesetup resistance in accordance with LRFD framework.Chapter 6 – Integration of Construction Control and Pile Setup Into Design:Development of regionally calibrated LRFD resistance factors for steel H-pilefoundation for dynamic analysis methods with considering pile setup. Integration ofconstruction control using dynamic analysis methods in pile designs based on aprobability approach. Compared the newly and regionally calibrated resistancefactors with the AASHTO (2010) recommendations as well as resistance factorsdetermined by other researchers.
