Where does the Allowable Bearing Stress Equation come from?
Where does the Allowable Bearing Stress Equation come from?
(OP)
For dowels in a concrete pavement, the allowable bearing stress is calculated as:
Fb = ((4-d)/3)*Fc,
where
Fb= Allowable Bearing Stress
d= Diameter of Dowel
Fc= Ultimate Compressive Strength of Concrete.
This seems backwards to me (Allowable Stress goes down as dowel size increases. And I can't find an explanation online. Does anyone know how this formula came to be?
Fb = ((4-d)/3)*Fc,
where
Fb= Allowable Bearing Stress
d= Diameter of Dowel
Fc= Ultimate Compressive Strength of Concrete.

I may be off base, and since I was not able to access the report I assume this was just a relationship found in a laboratory.
