Resistance to tearing between outer row of rivets:
Rto = ( P - D) t St
Resistance to shearing two rivets in double shear and one in single shear:
Rs = (5π d2 Ss) / 4
Resistance to tearing at inner row of rivets and shearing one rivet of the outer row:
Rtio = ( P - 2 D) t St + ( π d2 Ss) / 4
Resistance to crushing in front of three rivets:
Rc = 3 t d Sc
Resistance to tearing at inner row of rivets, and crushing in front of one rivet in outer row:
Rtr = ( P - 2 D) t St + t d Sc
The safe tensile load L based on single shear of the rivets:
L = n Ar Ss
The safe tensile load L based on bearing stress:
L = n Ab Sc
The safe load L based on the tensile stress:
L = Ap St
Efficiency of Design
η = [(safe tensile load L based on single shear of the rivets) / ( l t St) ] 100
Where:
Rto = Resistance to tearing between outer row of rivets (lbs)
Rtio =Resistance to tearing at inner row of rivets and shearing one rivet of the outer row (lbs)
Rs = Resistance to shearing two rivets in double shear and one in single shear (lbs)
Rc = Resistance to crushing in front of three rivets (lbs)
Rtr = Resistance to tearing at inner row of rivets, and crushing in front of one rivet in outer row (lbs)
L = Safe Tensile Load (lbs)
η = Strength of Joint / Strength of Un-riveted plate (%)
d = diameter of holes (in)
t = thickness of plate (in)
D = Diameter of the rivet (in)
tc = thickness of cover plates (in)
p = pitch of inner row of rivets (in)
P = pitch of outer row of rivets (in)
Ss = shear stress for rivets (lbs/in2)
St = tensile stress for plates (lbs/in2)
Sc = compressive or bearing stress for rivets or plates (lbs/in2)
