A comparative analysis of two bridges constructed with the most commonly usedgirder types in Florida is carried out. The girder types that the bridges areemployed for this study are AASHTO Type III (American Association of StateHighway and Transportation Officials) and Florida I-Beam. Two bridges that haveexactly the same specifications but with different girder type are analyzedunder baseline state and different prestress loss cases. Finite element modelsof these bridges are utilized and the FE models are subjected to two types ofvirtual load tests of Florida legal loads namely C5 and SU4. Florida I-Beamtends to have higher load carrying capacity, higher lateral stiffness, costefficiency and better element level reliability when compared to AASHTO Typegirders.
