PROBABILITY-BASED COST ALLOCATION OF BRIDGE FATIGUE DAMAGE
Federal Highway Administration (FHWA) highway cost allocation studies (HCAS) have been undertaken to determine the consumption of infrastructure by various classes of users as a function of the resources required to construct and maintain the system. An important consideration in the cost allocation of bridge expenditures is fatigue damage. Past HCAS have incorporated deterministic methodologies for fatigue damage evaluation of damage assigned to each of the truck vehicle classes and weight groups. Average weights and axle spacing are used to represent the distribution of vehicles in a particular class and weight group. Due to the large variation of several critical aspects of a fatigue evaluation for HCAS, a probability-based evaluation is a more rational approach. This paper develops the necessary probability-based HCAS framework to assess fatigue damage responsibilities. Vehicle load models, both currently available and required, are identified as well as highway bridge fatigue resistance models. Probabilistic evaluation techniques for structural reliability are then integrated into a new bridge HCAS evaluation methodology consistent with the established uncertainties.
