Project 2d: Calibration of Load and Resistance Factors in LRFD Foundation Design Specifications

项目名称：	Project 2d: Calibration of Load and Resistance Factors in LRFD Foundation Design Specifications
摘要：	The AASHTO LRFD Design Specifications for drilled shaft foundations are yet to be calibrated with test data in Missouri sites. Foundation is a critical part of a bridge system. It not only affects the stability of the overall system, but also constitutes a significant portion of the bridge construction costs. Therefore, better calibrations with field tests are imperative. Additionally, foundation design calibrations warrant the consideration of a bridge system and thus require a close collaboration between geotechnical and structural engineering. Typical bridges will be analyzed to understand the demand (load factor) on drilled shaft foundations and the required strength (resistance factor) given a certain allowable displacement. Both load and resistance factors will be calibrated with the Missouri environment and traffic condition using a reliability-based approach.
