1950's Bldg - Precast Double Tee Capacity
1950's Bldg - Precast Double Tee Capacity
(OP)
I'm looking at a precast double-tee roof structure for a bldg constructed in the 1950's. The owner wants to add additional load on the roof and does not have plans for the bldg nor could I find any markings in the field that would distinguish a manufacturer. What kind of procedures if any could I follow to determine the members capacity?
TIA

To find out the exact quanty of strands, try to perform non destructive testing like GPR, etc. To find out actual concrete strength, take some cores from the actual member.

How would this tell you anything about capacity?
