Wheel Load Distribution on Road Plate
Wheel Load Distribution on Road Plate
(OP)
A collegue of mine asked me about the proper wheel load distribution for H-20 loading on a temporary "road plate" used to cover a trench.
Looking through the AASHTO code, I didn't find anything applicable to spanning with plate steel. Did I miss it somewhere?
Thanks for all of the tips. I read much more than I post...

with a: being the short span
b: being the long span
Point load short span is b^3/(a^3+b^3)
Point load long span is a^3/(a^3+b^3)
Some judgement will be required to establish the effective width of plate that carries the wheel. But with the wheel contact area of 20", I would not hesitate to double that width for the effective width of plate.

Is that AASHTO distribution above based on plate supported on two sides or is that for support on four sides?
