In this study, live load distribution formulae for the girders of single-span integral abutment bridges (IABs) are developed. For this purpose, two and three dimensional finite element models (FEMs) of several IABs are built and analyzed. The analyses results are then used to development of live load distribution formulae to estimate the girder live load moments and exterior girder live load shear for IABs with prestressed concrete girders.
