1940's Rebar Fy
1940's Rebar Fy
(OP)
I am looking at a reinforced concrete building from the 1940's. The drawings indicate Fs = 20 ksi. Until we have the rebar tested, I planned to use Fy = 30 ksi to run preliminary numbers to estimate the loads this building can carry.
Does anyone have experience with rebar of this vintage? What values of yield strength should we expect?

Don't forget if your tests confirm a higher yield you may still have a development problem if your bars have the low deformation ribs of the 40's.
