In this study, the effects of soil bridge interaction and abutment deck continuity on the live load distribution in integral bridge components are studied. For this purpose, 2-D and 3-D structural models of typical integral and conventional bridges having various structural, geometric and geotechnical properties are built. The analyses of the models are then conducted under AASHTO live load. The analyses results revealed that soil-bridge interaction has significant effects on the live load distribution in abutments and abutment deck continuity has considerable effects on the live load distribution in girders in short-span bridges.
