Load Rating of Highway Bridges
presented by Farhad Panthaki

This presentation will provide bridge engineers with the fundamental knowledge about load rating of highway bridges. The three methods of performing load ratings described in the AASHTO Manual for Bridge Evaluation, namely Allowable Stress Rating, Load Factor Rating and Load and Resistance Factor Rating will be discussed along with illustrative examples of various structure types. The presentation will discuss various approaches to enhance the qualitative understanding of load rating results to ensure that the results are within an appropriately reasonable order of magnitude. The effect of material deterioration on load rating capacity and the consideration of potential alternate load paths will be examined. A description of the load posting process based on the results of the load rating will also be presented.
