FIN PLATE CONNECTION
The shear capacity of the net section is given by:
P v = 0.7pyKeAv,net

Block shear
The block shear capacity is given by the following expression:
Pr = 06 . pyt[ Lv + Ke( Lt - kDt)
]
Lv= e + ( n-1) p = 40+ ( 4-1) 80
= 280 mm
6.2.4
t = 10 mm
Ke = 1.2
Lt = 50 mm 3.4.3
k = 0.5
Dt = 22 mm
P r = 0.6 ¥ 275 ¥ 10[280 + 1.2(50 - 0.5 ¥ 22)] 6.2.4
= 539.2 kN
The shear capacity is given by the net shear capacity at the section
P v = 462 kN
462 kN > 110 kN
Therefore the shear capacity of the fin plate is adequate.
