The Wave Equation Analysis of Pile Driving program (WEAP) is an industry standard computer program used to study pile drivability issues, pile driving stresses and estimate pile load bearing capacity while the pile is being driven. Starting in October 2007, the FHWA required states to use the new AASHTO LRFD Bridge Design Specifications. It is known for ODOT that by using the AASHTO LRFD default WEAP resistance factor will result in significantly more conservative pile designs than those prior under allowable stress design (asd) prior to LRFD. This will result in much more expensive foundation costs for bridge construction using driven piles. The objective of the research is to recalibrate the LRFD resistance factor for ODOT standards of practice under initial driving and restrike conditions for use with the WEAP program. Dr. Smith will present the current findings of the research. For more information contact: Trevor D.
