Hybrid Crane Runway Beam, Fb?
(OP)
When analyzing a "hybrid" crane runway beam that is a combined section with different grades of steel (S-shape- 50ksi, strong axis, with a Channel-36ksi at top flange, weak axis), how do you account for the combined different grades of steel when computing the allowable bending stress, Fb?
Would it be similar to the hybrid girder factor, Re, in Plate girder design, when the flanges and webs are made up of different grades of steel.

At any rate, I designed countless crane runways using same section combination you are talking about using A36 steel.
Good luck
