LRFD General Design
Use Resistance Factors for Driven Pile found in AASHTO 9th Ed. Table 10.5.5.2.3-1. For soils side resistance in static design, use the Norland/Thurman method in cohesionless soils in accordance with AASHTO LRFD Bridge Design Specifications Article 10.7.3.8.6f, and the a-method in cohesive soils in accordance with AASHTO LRFD Bridge Design Specifications Article 10.7.3.8.6b.
TxDOT utilizes static analysis for design and dynamic analysis for acceptance of driven pile foundations.
