I’m looking for documents on the old gypsum bulb tee roof construction. I have a building the was built in 30’s or 40’s. I would like to learn more about this system. Is it a precast panel system or was it poured in place? I tried a search of the SEAInt archives, but for some reason it searches the entire web and not just the archives.
It has joists at 8 ft on center and bulb tees at 30-32” on center. I want to find out the load capacity of the roof deck and weights.
I don’t have a thickness of the roof. Did they make it in different thicknesses?
Thanks for your help.
