Conditions to be met for 4 Bolts Unstiffened End Plate Connections are checked as specified in TBDY APPENDIX 9B.
The Requirements to be Fulfilled
It must be capable of providing the relative storey drift angle of at least 0.02 radians for limited ductility level and at least 0.04 radians for high ductility level as specified in Annex 9B,
For hot-rolled wide flange sectionsesections, the details below should be followed.

The Vuc used in the dimensioning of the connection is determined according to the equation in the figure above by summing the shear force determined on the basis of the yielding limit state with the shear force calculated from the combination of 1.2G + 0.5Q + 0.2S on the plastic hinge at the end of the beam.
The shear strength required for the panel zone is calculated by using the column shear force generated by the possible plastic moments of the beams connecting to the column.
