Plate Thickness Design
Plate Thickness Design
(OP)
I have a problem, I think I solved it myself, BUT I would like a second opinion:
I have a plate 24.375"x23" with an 18,000lbs load in the centre. It's not a point load, it is load from a forklift tire, so I considered the load to be on a 4" radius circle in the centre. I want to know how thick the plate should be, given it is going to be made from A36 steel plate, with a safety factor of 2 therefore a maximum design stress of 18,000psi.
Thanks,

For a plate to be "rigidly fixed", it means that the edges of the plates can transmit moment into the structure that is supporting the plate. What type of connection is it? ... Bolted, welded, embedded? The actual edge condition will govern what type of edge condition to use.
Hope this helps,
Mike

Alternatively Roarkes Formulas Art. 10.11 give formulas to calculate stress for various edge conditions.
