JTRP Technical Reports
Results of the load tests of two steel through truss bridges were used to evaluate the assumptions used by BARS for the rating of this type of bridge. Based on the results from this study it is recommended that the Indiana Department of Transportation use the load distribution factors in the 1994 LRFD Specifications in the rating of these bridges. This will imply replacing the load distribution factors currently in BARS. The implementation of the new distribution factors will result in a less conservative rating of the longitudinal beams in this type of bridge. The increase in the allowed moments …
