Composite slab in 1960's
Composite slab in 1960's
(OP)
Does anyone know what the yield strength for steel shear studs used in composite construction in the 1960's was?
When was the last time you drove down the highway without seeing a commercial truck hauling goods?

0.5*As*sqrt(fc*Ec)
This is very similar to the equation given as I3-3 in the current steel spec. The major difference is that equation from 1971 does not have a limit based on steel strength.
They also give the equation that the ASD provisions of the 1969 spec are based on, and it is only a function of concrete compressive strength, and is only valid up to 4 ksi concrete compressive strength. This equation is 37.45*As*sqrt(fc), with fc in ksi. The safety factor was 2.5.
