Plate buckling and steel strength
Plate buckling and steel strength
(OP)
Folks,
Why is the plate buckling strength based on the inverse of sqrt(Fy), meaning why is the a thicker plate needed if I am using 50 Ksi versus 36 Ksi.
Thanks

It's likely that you are not using the same code, but I'm sure the same principles apply.

Thanks, that helps.
RE: Plate buckling and steel strength
The Euler buckling unit stress is a function of b/t, E and poison ratio, but independent of yield stress. The phenomenon, that larger t is required for higher grade plate in concern of buckling, is due to AISC's intention to ensure buckling will not occur prior to reach full yield strength, and is the result of equating Fcr >= Fy.
Glad to have a free refreshment session. Thanks, fellows.
