Abstract: Sustainable engineering requires that engineering products are not only socially acceptable, economically feasible, and environmentally friendly, but also safe against all possible serviceability and ultimate limit states. Laterally loaded piles are mostly designed against the serviceability limit state of excessive lateral deflection. This study takes into account the uncertainties associated with the response of laterally loaded piles and focuses on their load and resistance factor design based on the serviceability limit state of excessive lateral deflection. Resistance factors are obtained for laterally loaded piles embedded in clay deposits in which the soil properties are assumed to be random variables. Pile capacities are determined based on a specified allowable lateral deflection at the pile head. The pile load-displacement curves are generated using the p-y method. Model uncertainties and bias factors are incorporated in the analysis. The uncertainties associated with the lateral capacity, for a specified lateral head deflection, are quantified, and the probability distribution of the lateral capacity is determined using Monte Carlo simulations. The applied dead and live loads are assumed to follow normal and lognormal distributions, respectively. First order reliability analysis is then performed using the distributions of loads and capacity to determine the load and resistance factors. � 2014 American Society of Civil Engineers.
