Design of Steel Plate
Design of Steel Plate
(OP)
Can anyone point me to a link or documentation that shows design guidelines for a simply supported steel plate? I am applying a 10.4 kip load to a 10.7 inch wide by 52.2 inch long plate (1/2" thick). I am getting a quite larger bending stress than the allowable 66% (bending stress) and wondering if I'm missing something. Are there any allowable reductions when it comes to design of plates?

I don't know much about statistics, but I do know that if something has a 50-50 chance of going wrong, 9 times out of 10 it will.

One half inch plates are not really that good in bending. That's why they make so many steel shapes.

You're also way beyond yield on the steel.

In my research, I have come across some equations for plate design. However it wasn't clear to me as to what kind of streesses they were aimed at calculating. Do you know of any that are strictly used for design of such a plate in bending and shear? Thanks.

I assume you do civil work, but not structural, as your question is elementary structural stuff.
For bending, M=PL/4 for concentrated load at centre span
Elastic section modulus S=bd^2/6
Bending stress f=M/S
Deflection = PL^3/48EI

The first reason for my post was to see if there were any assumptions/equations (since I don't regularly come across plate design) that I was missing other than the basic equations. Such as the post by Johnny.
It sounds like my results are matching those equations used by Hokie and results by Jed.
The second reason for posting my question in an elementary format was also to keep the question as simple as possible since my results are in disagreenment with a co-worker and I wanted to compare his assumptions as well.
Thank you everyone for your help. Greatly appreciated.
