Anyone know where to find design values for gypboard? Not that I want to design with it...
Simply, I've been asked to determine if a mobile machine crashes into a fire rated gypboard wall, will the gypboard be compromised.
sc - Yes, gypsum based plaster sheathing. Sheetrock, even. It could be supported by timber frame or metal stud or other. The particular case I was asked about was metal studs at 16" o.c. I've never considered gypsum board as having any real structural value. Go take a hammer and see how easy it is to knock a hole in your wall. Thats why it took every bit of self control to prevent me from bursting out in laughter when I was asked what force from a mobile machine (forklift, scissorlift, etc.) would compromise the wall. Hell, my foot would compromise the wall.
U.S. Gypsum Co. use to publish the a booklet called (I think) "The Gypsum Handbook" in which had EVERYTHING you ever wanted to know about sheetrock walls and ceilings. If you can't get one at your local drywall supplier try the USG website.
