A framework is presented for the assessment of the safety of a bridge deck, taking account of its 2-dimensional nature. Random field analysis is proposed to determine the spatial distribution of resistance probability but is not implemented in this paper. Monte Carlo simulation, calibrated using Weigh-in-Motion traffic data, is used to determine lifetime maximum distributions of bending moment throughout the bridge deck. The 2-dimensional approach is shown, for the example considered, to give much lower probabilities of failure than the alternative approach of considering points one by one.
