(OP)
I never understood why on earth shear lugs would experience bending. I simply can not fathom it. Any comments?
When was the last time you drove down the highway without seeing a commercial truck hauling goods?

it may not behave exactly as per formula but hell everything in structural world doesnt exactly behave per formula.. aisc gives you an estimate that works..

My experience is that shear lugs are designed as cantilever beams. I have also seen this done in different parts of the world as well as in NA. Most people use AISC Design Guide 7 Industrial Buildings or something similar as guidleine.
I can't think of another, at least simplified way, of performing the design other the cantilevered beam method. Simply looking at the entire shear force acting over the width (not depth) x the thickness does not seem right to me because the force is distributed. In a short lug the shear may govern over flexure but I have never seen that to be the case.
Do you have another method that you use?
