The results of the full-scale bridge testing program to determine the lateral load distribution of load on 2 multispan continuous steel beam slab bridges are presented. The details are outlined of rolling load tests, static load tests to failure, instrumentation, results and data interpretation. The rolling load data suggest that, for a particular bridge, the lateral distribution of load depends almost entirely on the lateral position of the vehicle on the bridge. the static load test data indicate that, as the load on a bridge is increased up to the order of magnitude that produces first yield of steel, the load distribution coefficients are not significantly affected. The AASHTO specifications require distribution factors that are slightly conservative for interior girders and slightly unconservative for exterior girders, indicating that they do not fully account for the additional stiffness contributed to the exterior girder by curbs and rails. Further conclusions with respect to the Sanders and Elleby equation, the distribution factors predicted by the STRUDL II models, and the AASHTO requirements are presented.
