Steel Plate Bending Stress

[nsinma]

AISC - ASD 9th Ed. allows a stress increase for bending in plates of 25% (or .75 Fy, Eq. F2-1). Is there a similar increase in the AASHTO code?

Try reposting this in the Bridge Engineering Forum. A little more detail about you question will help. I think you are refering to ASD and bending of plates about the weak axis. Is that right? In the AASHTO 16th edition section 10.32.4.2 allows using 0.8 Fy for stress in exteme fiber for pins, rollers and expansion rockers.

Yes, weak axis bending. Its for a base/bearing plate.

I'll try the bridge forum. Thanks.
