Implementation of the AASHTO LRFD Code in Geotechnical Design Piles
The LRFD AASHTO code (2007) includes substantial changes compared to the AASHTO Standard Specifications (2002). Therefore, State DOT's have to review their current practice and, if needed, develop a new approach that is consistent with the LRFD philosophy. Load and resistance factors in LRFD code were determined in the reliability-based calibration process. However, this calibration was limited to the superstructure. The resistance factors for the piles were mostly based on engineering judgment. Therefore, there is a need for verification of a pile design provisions. The objectives of presented study were to review the available pile capacity analysis methods and develop a user-friendly and possibly more accurate formula. In addition, a procedure was developed for comparison of the pile design and the calculation of the resistance factors.
