I'd have to pull out my AISC manual to be sure, but I believe that a

comparing single shear to tension, then I agree with you.


What is "double shear" and "single shear"?

It refers to the number of planes in shear. Think of the rivet in a
scissors. There is one shear plane where the two halves of the scissors
meet and are held together by the pin/rivet.

Now think of a sandwich of three pieces of metal held together with a
bolt or pin or rivet. There are now two planes that are in shear and
thus you have twice as much shear resistance of the outer two pieces of
metal are pulled one direction and the middle piece is pulled another
direction.
