Load Rating of Concrete Bridge without Plans
Combining theoretical analysis and field tests can greatly enhance the understanding of the performance of the bridges for engineers, which can be applied to evaluate the load carrying capacity of bridges without plans. Researchers at the University of Delaware previously developed a methodology, the steel area method (SAM), to rate concrete bridges without plans, which uses strain or displacement measurements from field testing in conjunction with basic mechanics principles to estimate the unknown area of reinforcing steel in a concrete bridge. The estimated reinforcing steel area can then be used with traditional rating techniques. In this paper, the SAM procedure has been extended and improved to accommodate more realistic general load configurations used in a typical load test. A procedure for load rating bridges without plans incorporating the results of a diagnostic load test is proposed based on the improved SAM approach. A concrete slab bridge with original structural drawings is used to validate the proposed procedures. Conclusions of the proposed methodology are drawn based on the test verifications.
