1) Given Data
P = kN tm = mm n = mm
py = N/mm2
tg = mm d1 = mm
ps = N/mm2
d = d2 = mm
pbs = N/mm2
As = mm2
s = mm
pbb = N/mm2
kbs = m =
V = kN Lv = mm yc = mm
dp = mm Lt = mm Dt = mm
be = mm Ke = k =
Bolt Grade = 8.8, threads exclude from shear plane
2) Max. Force at Bolt
R = [(P/n + P*e*y1/S(x2+ y
2))
2+ (P*e*x1/S(x
2+ y
2))
2]1/2
= kN per bolt
S(x2+ y
2) = mm

e = d2 - yc = mm
3) Bolt Capacity
By Shearing:
6.3.2.1 Ps = m*ps*As = kN per bolt
By Bearing:
6.3.3.2 Pbb1 = d*tg*pbb = kN per bolt
Pbb2 = m*d*tm*pbb = kN per boltPb = Min(Ps, Pbb1, Pbb2) = kN
ok!
6.3.3.3 4) Bearing Capacity of Connected Part
Pbs1 = m*kbs*d*tm*pbs kN per bolt
Pbs2 =m* 0.5*kbs*d1*tm*pbs = kN per bolt
Pbs3 = kbs*d*tg*pbs = kN
Pbs4 = 0.5*kbs*d1*tg*pbs =
Pbs = Min(Pbs1, Pbs2, Pbs3, Pbs4) = kN ok!
6.2.4 5) Block Shear Capacity
Pr = m*0.6*py*t*[Lv + Ke*(Lt - k*Dt)] = kN ok!
6) Gusset Plate
Shear Capacity:
4.2.3 Vc = 0.6py*0.9*tg*dp = kN ok!
Tension Capacity:
4.6.1 Tc = py*tg*be = kN ok!
