Check 5 – Bearing capacity of flange cover plate connected to column
flange
The basic check is that the bearing capacity of the flange cover plates
( SPbs) must be greater than the applied tensile force (Ft).
Top bolts
SPbs ≥ Ft
The bearing capacity of the top bolts is given by the following
expressions:
Pbs = kbs d tp pbs

Pbs £ 0.5 kbs e tp pbs
