Steel plate analysis for point load question

[gjb2]

I am looking for a design reference for checking a steel plate for bending due to a point load in the center. The simplest way to explain what I'm looking for would be to consider a steel plate welded all around to the end of an HSS tube. Then put a bolt through the middle with a point load.

Does anyone know of a good design reference for a simplified analysis for this condition? I don't have access to FEA computer software.

I found this thread after doing a little more searching:

That was helpful. Thanks eng-tips.

Yield line analysis is the easiest way to find the ultimate load, but you have to decide whether the plate is hinged, fixed or partially restrained on each edge.

If you want an elastic analysis, consult "Theory of Plates and Shells" by Timoshenko and Woinosky-Krieger.

The only issue I have with a yield line analysis is that it gives so much extra capacity that if you use it for design of a new plate, you could easily get yielding under service loads (because the ultimate capacity will be much greater than 1.6 times the yield capacity, and your load factor won't be more than that).
