Re: Proportional Limit, A36 Plate

[Subject Prev][Subject Next][Thread Prev][Thread Next]

Can I count on the *yield* for A36 plate being over 36ksi, or can I assume
the proportional limit as equal to *yield*?  My only reference leads me to
suspect that the proportional limit for steel could be as much as 10
percent below yield.

There's a reason for this exercise -- I'm checking a stack per ASME
STS-1-1992 (the latest according to ASME website).  If the proportional
limit is significantly less than yield, my allowable bending stress will be
lessened substantially.

Thanx,

Fountain

Fy for ASTM A36 steel plate is 36 ksi up to and including a thickness of
8".
Above 8" thickness, it is reduced to 32 ksi.
