Step I
list bolt value
shear capacity of bolt=fub×Anb×nn√3Ymb
=400×245×1√3×1.25
Vdsb=45.26 kN
bearing capacity of bolt=2×Kb×d×t×fu
find kb
e3do=403×22=0.60
P3do=0.25=803×22=0.25=0.96
fubfu=400410=0.97
Vdpb=2×0.6×20×10×410
Vdpb=98.4kN
Step II
Direct force per bolt or load in each bolt
F1=$\frac{load}{No.\ bolt …
