1900's building-structural steel strength
- Thread starter ick2
- Start date
There were numerous types of steel in use in the early 1900's - per AISC, the governing specification would be ASTM A9 - which had:
Rivet Steel - Fy=25-30 ksi
Fu=50-60 ksi
Medium Steel - Fy=30-35 ksi
Fu=60-70 ksi
These above values are for dates up to about 1908.
For dates up to 1931:
Structural Steel - Fy = 27.5 to 32.5 ksi
Fu = 55 to 65 ksi
Rivet Steel - Fy = 23 to 28 ksi
Fu = 46 to 56 ksi

You would be wise to get sample coupons from steel in the building and have them tested. Use the above values for preliminary work only.
