Crane Runway Beam Modification

[Andrewstructure]

I have a client who has modified his crane runway beams with plates connecting the edges of top and bottom flanges of the plate girder (see attached image). He wants me to analyze the section to determine an allowable crane capacity.

My plan is to ignore the interior web and analyze the section as a box section, using AISC LRFD section F7.

Any comments?
