Steel Plate Thickness Design
Steel Plate Thickness Design
(OP)
I am looking for design examples (specifically for selecting plate thickness) regarding steel plates subject to bending. Does anyone know of a website or reference material that may help?
I have been taught to find the moment applied to the plate and corresponding Smin (Smin = M/0.9*fy). Using the Smin I find the thickness based on the geometry of a rectangular section as follows:
S = (b*d^2) ; where, d= plate thickness= t, b= effective width
6
Therefore, t^2 = 6*Smin
b
However, what is the appropriate method for determining the effective width of the plate (for example, a 2m wide plate spanning 610mm.)
Thank you.

For a uniformly distributed load on a one-way plate, the effective width of the plate will be the actual width. For a point load at mispan on a one-way plate, the effective width will be approximately equal to 60% of the span.
You may find some relevant formulas at www.xcalcs.com. Make sure you understand the principles behind the spreadhsets rather than blindly populate them with data.

I use about 40t, from Troitsky's "Tubular Steel Structures" in section under Bins and Bunkers.
