In this study, the effect of soil-bridge interaction on the magnitude of the internal forces in integral bridge (IB) components due to live load effects is studied. For this purpose, structural models of typical IBs are built by including and excluding the effect of backfill and foundation soil. The analyses of the models are then conducted under AASHTO live load. In the analyses, the effects of the backfill and foundation soil on the magnitude of the internal forces in IB components are studied for various structural, geometric and geotechnical parameters such as bridge size, abutment height and thickness, pile size and orientation, number of spans and foundation soil stiffness. The analyses results revealed that soil-bridge interaction has a significant effect on the magnitudes of internal forces due to live load in the components of IBs.
