@bridgesmith, I have the span of the beams. And sorry for the confusion the beams are single-tee prestressed concrete. I am only an intern so I am new to a lot of this stuff. The only thing I don't have is the number of strands and the strand diameter.
Heys guys,
I'm currently working on a project that was done in 1970. The ceiling is made up of 36" depth 8' wide precast tee beams. The engineer on the job at the time marked the tees as Wincrete #36T247C 4-5.
I cannot find anything online or in our library about Wincrete or the beam...
