The AASHTO LRFD Bridge Design Specifications allows the use of either of two design methods for precast reinforced concrete pipe; the indirect design method or the direct design method. The indirect design method relates the strength of the pipe in the field condition to its three-edge bearing strength tested at the plant. The majority of reinforced concrete pipe designs are performed with the indirect design method, resulting in one of five pipe classes or a specified D-Load. The indirect design method is one of the most complete design methods used for buried drainage pipes, while also being one of the quickest to perform. Join this webinar to learn how to design RCP with the indirect design method.
