Abstract:The Mississippi Department of Transportation (MDOT) currently uses LRFD. However, the LRFD resistance factor used does not necessarily represent the Mississippi soils. A pair of authors have already calibrated LRFD resistance factors for other states using First Order Second Moment (FOSM). However, FOSM leads to over-conservatism. Thus, this study calibrated LRFD resistance factors using the First Order Reliability Method and Monte Carlo Simulation (MCS) rather than FOSM. MCS was found to be the most efficient method. Moreover, pile setup factors were obtained in different sets of data. Finally, the calibrated resistance factors were compared with the recommended resistance factors from published studies from the federal government and the state of Alabama in terms of accuracy. The resistance factors generated in this study are recommended for use based on MDOT’s design methodology.
