A bridge crossing hanging support system is to be designed for a suspended duct system between the steel I-Beams of a bridge. Holes will be drilled in the steel I-Beams to fasten(Steel Bolts) the duct supports to them. Do the bolts and steel members of the supporting frames for the duct system have to be selected based on the standards set by AASHTO? Pleas advice
