Does anyone have a website link or library reference for how to claculate/determine the weight bearing capacity of the floors in residential structures? Or know a structural engineer who does this type of analysis? I don't want to overload the capacity of my new (new to me, built in 1990, block and beam) home's floor/foundation. I'm a bookophile, love antiques, and have a waterbed for my bad back. In short, my "stuff" weighs a couple of tons, probably more. BTW, this is one of the most useful forums I've ever seen! Y'all are GREAT PEOPLE!!!
