Thank you, JAE. It is a good place to start. The cover has a picture of a bridge crane very similar to condition for my project.
Bridge crane is one of many design items I have. I have a light rail train coming into a building. At the grade level, there are drop tables which transport trucks (single wheel assembly for a train) down to the basement level and turntables which rotate to transport the truck to the adjacent track. There are many special situations where I am provided with a manufacturer supplied equipment with capacity (hoist, monorails, catenary wire supports, etc) and I haven't done enough industrial structures enough to know what typical load factors apply to certain conditions. I've been designing more standard structures like offices, residential, commercial, schools, hospitals etc and almost none for industrial so I need to get educated on potential pitfalls and areas to watch for. Once I determine a proper design loading and where elements belong, design should be pretty much the same...
Perhaps there isn't a published book on this sort of structure, but I'd welcome any other suggestions.
Cheers.
