    Where does the Allowable Bearing Stress Equation come from?

    Thanks for your help. I'm not sure I'm 100% on board just yet. If the shear area decreasing causes the bearing stress to decrease, why would the shear area not be in the equation? This equation (from ACI Committee 325, 1956) does not take into account slab thickness, thus not the area beneath...

    Where does the Allowable Bearing Stress Equation come from?

    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...
