This report describes a methodology for analysis and load rating of pre-flex beams subjected to vehicular and military loads. The methodology is based on service limits for different loading stages. The analysis is divided into an initial stage of pre-flexion of the non-composite beam, followed by the release and subsequent states of loading of a composite beam. Creep and shrinkage effects are considered in the analysis adopting Giacomo and Maninni 2006 and ACI 209 1992 methods. An example bridge was used to describe a step-by-step process of analysis.
