Hello, I am designing an underhung crane that we will use on a bridge project. the runway beams will be attached to the floorbeams that run transverse to the roadway with Lindaptor Clamps. I am using CMAA 74, AISC dg 7, AISE rpt 13, and a few others along with osha. my question is combining the longitudinal bending stresses (fbx,fby,fb torsion) with the local flange bending generated by the lindaptor clamps clamping onto the runway beams. In the past I have used sqrt(sum of squares) in different applications. This approach seems like an average of the von Mises method, with shear almost dropping out. with von Mises, the +/- (fbx)*(fby) value adds or subracts depending on which side of the flange you are evaluating. Any thoughts? i am thinking the sum of squares method is acceptable.
i have attached a page from a Lindaptor data sheet that shows how these clamps can be used.
