Efficiency of a Riveted Joint

Efficiency of a Riveted Joint Points : Efficiency of a Riveted Joint Efficiency of riveted joint is clear as ratio of strength of riveted joint to strength of the un-riveted or solid plate.
Strength of the riveted joint = Least of P_r, P_s and P_c
Strength of the un-riveted or solid plate per pitch length, P = p × t × σ _t

Efficiency of the riveted joint,
Π= Least of of P_t, P_s and P_c/P X t X σ _t
p = Pitch of the rivets,
t = Thickness of the plate, and
σ_t = Permissible tensile stress of the plate material.
