The rating of an existing bridge on a low-volume road can be a very labor-intensive assignment. Because most bridges on low-volume roads are located in local jurisdictions, resources for computers and bridge inspections and repairs are limited. Therefore, to increase the productivity and improve the rating procedure, a software system has been developed to run on microcomputers. This system is made up of two programs, KU-SBAR and KU-STAR, written to rate simple and continuous span girder-type and simple truss bridges. Both programs follow AASHTO rating procedures. Five standard AASHTO trucks and one user-defined truck are supported. A wide range of output options is provided to the user. These include a rating summary, moments, shears and reactions, member stresses, and nodal deflections. The system was run on microcomputers with two different microprocessors. One was found to run approximately 2.5 times faster than the other. It was demonstrated that analyzing and rating existing bridges on low-volume roads is feasible with the aid of a microcomputer. Although the analysis and rating phase is only a portion of the entire rating process, the use of the bridge rating system described is one means of improving productivity and rating options for transportation officials and engineers.
