I have an old building to evaluate. Anyone know what was the strength of steel they used in 1957. I usually take an allowable of 20ksi, but I'm fairly close to the limit. Anyone??

Per AISC Iron & Steel Beams 1873-1952 and FEMA 356, yield strength not less than 33 ksi. Allowable tensile stress of 20 ksi.
