Is triple shear of bolt possible?
Is triple shear of bolt possible?
(OP)
Bolts subject to shear are designed for both single and double shear. Double shear stress is half of single shear stress in case of same bolt. If double shear is better than single, why don't we use there triple shear, or quadruple shear, etc.? could you explain why triple share is not possible or effective?

I like a lot of things about the AISC standard for steel construction, but a detailed commentary would sure be nice. That and a little less recipe-book wouldn't hurt. I think sometimes it fails the user in trying to be so easy to use; a touch too prescriptive for my taste, though I often will read it first when learning something new!
Note that in CSA S16 the shear of bolts is Cl 13.12, and
Vf = 0.6∅b(n)(m)AbFu.bolt
Where n = number of boots
m = number of shear planes
Note that there is no code-imposed limit to the number of shear planes.

because you can break your triple shear connection down to double (and single) shear elements.

Tripple and beyond are rare. Rare doesn't fit into AISC's simplified approach of "Want X? Do this, in this exact way".
Mind you that makes the AISC VERY user friendly... Just doesn't help you here.

quadruple shear is 2 x double shear
etc etc

3/2 of double shear had better be the same as 3 times single shear, otherwise there is something wrong...

Three plates yield two interfaces = double shear.
Four plates yield three interfaces = triple shear, this is unbalanced but so is single shear.
Five plates yield four interfaces = quadruple shear.
A rule starts to show, there is/are one less shear plane(s) than the number of plates.

trpile shear means (to me) that there are three shear planes carrying the load (one lug in double shear, one in single)
