Comparative analysis between testing and theory, the live-load distribution of I-type simple span slab-on-girders bridge is studied based on structure characteristic of this type bridge. In order to identifying the carrying capacity of I-type flitch beam bridge, the deflections and stresses of different beams are analyzed through test and theoretical analysis based on different load conditions. During the period of theo- retical analysis, the model of bridge is built using Dr. 3.0. At the same time, the comparative research among finite element method using ANSYS , slab （girder） with transverse rigid joints and testing, the resuits confirm the feasibility of theoretical method. At last, the project propose the live-load distribution coefficients which suits for this type bridge is suggested.
