resources for poured gypsum bulb tee roof construction
i am looking for resources for poured gypsum bulb tee roof construction. we are doing some renovations to an existing building, built in 1957, and i can't find the information i need to determine the horizontal diaphragm capacity of the existing roof. the roof construction is 1/2" formboad, with #134 bulb tees @ 24" oc (i think... these old smudged drawings are tough to read!) reinforcement is galvanized welded wire fabric of #12 wire @ 4" oc across bulb tees and #14 wire @ 8" oc parallel to bulb tees. any links/tables/articles would be great... thanks!

in 1957, engineers typically did not worry about diaphragm action in roofs of this sort, so i wouldn't expect to find the information you need.  if the gypsum was only poured to the top of the bulb tees, i doubt you could depend on much diaphragm action.
