Bending Capacity of Plate (Strong Axis)

Bending Capacity of Plate (Strong Axis)

Bending Capacity of Plate (Strong Axis)

(OP)
Hi,

There's equations out there for bending capacity of plates in weak axis (either elastic or plastic modulus), however I've never come across a bending capacity for a plate in strong axis.  Also, this would be for a laterally unsupported plate, so I'm positive there are lateral-torsional buckling effects associated with the loading orientation.

Is anyone aware of any guidance available in either the CISC or AISC, or other?  This seems like it would be a very simple exercise, however I cannot seem to find any guidance with treating laterally unsupported plates in strong axis bending.

Thanks!

RE: Bending Capacity of Plate (Strong Axis)

I remember seeing something in that AISC "red" book (Design of Steel Connections?).  The approach was to check b/t of the plate, using 1/2 of the depth of the plate for "b", because only 1/2 of the plate is in compression.  This is also how you check the web of a beam which is coped at both flanges.

Section F11 of the AISC 13th edition has what you are looking for.

RE: Bending Capacity of Plate (Strong Axis)

Yes its explicitly covered in 13th Edition as jonnycash pointed out.  Another reason to move forward from the 20+ yr old green book...

Thanks all for the info.  I'll check in with one of our US offices and hopefully they can PDF me a copy of that section.

RE: Bending Capacity of Plate (Strong Axis)

Buy the book?

RE: Bending Capacity of Plate (Strong Axis)

You can download the spec for free at AISC (I'm not sure if you have to be a member or not).  You can't get the whole manual, but you can get the spec section that you're interested in.
