Abstract:The objectives of this research are to recalibrate the FHWA-modifi ed Gates equation
and update the associated LRFD resistance factor for pile types and local soil conditions
encountered in Louisiana. This research is consistent with FHWA recommendations
that “Highway agencies should establish long-term correlations between pile capacity
predictions from dynamic formulas and static load test results to failure.” Improved
consistency relative to the current design approaches will be achieved if the updated
resistance factor matches or exceeds the worst-case resistance factor used by the
DOTD, which will reduce confusion among users. Updating the resistance factor will
also serve to increase confi dence in the FHWA-modifi ed Gates equation, refi ne the
state-of-practice in LRFD, optimize the effi ciency of the piles, and reduce project
costs. It may also identify the need for an alternate pile verifi cation approach for small
projects.
