Check the shear connection for the IPE450-S275 for the design shear VEd=300KN. Bolts M20-8.8, plate thickness t=15mm.
e 1=60mm > 1.2*do=1.2*22=26.4mm
e 2=50mm > 1.2*do=1.2*22=26.4mm
e 1, e 2< 4*t+40=100mm
ρ1 and ρ2< min(14t,200)=210mm
Every bold gets vertical force 300/3=100KN and the torsional moment is 300KN*50mm=1500KN*cm and it is assigned at the farthest bolts as horizontal force 1500KN*cm/20cm=75KN.
At the farthest bolts the maximum force is
