I’m designing some checkered plate and need to stiffen it flexurally. What is the effective plate ‘overhang’ beyond the ‘L’ stem that I can use? Is it limited by b/t ratio?

Probably, but it also depends on the ratio L/S where L is the span. The effective width of plate varies with load type, uniform load being more forgiving than concentrated load. It should be safe to assume an overhang width of the lesser of 16t or S/4.
Thanks… I’ve usually used 16t, but had no handle as to why.

@BAretired This is what I’m looking at doing… with the stiffening angles falling short of the support and the plates attached to the supporting beam. Does anyone see any issues with this. It’s used for pallet support with LL=400 psf. It works structurally and the angle weld to the plate is 4@12 intermittent. I’ll have 6" of 1/4" fillet weld at each end.
