• 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.
