We are involved in evaluating a building built in 1976.  The roof deck 
is called out as 18ga x 0.11 (4.5") "T" steel deck. 
It appears to be L shaped rotated 90 degrees so that the short leg 
points downward.  The horizontal leg shows two small
valleys (crimped).  The deck is simply spanned between W beams at 14 
foot oc.  We are interested in finding out the
allowable loads and the dimensions of the legs (ie section properties) 
so we can determine if the deck can handle negative
moments if intermediate supports are added.
