be Fulfilled
It must be capable of providing a rotation the relative storey drift angle of at least 0.02 radians for the limited ductility level specified in Annex 9B, and at least 0.04 radian radians for high ductility level .as specified in Annex 9B,
For rolling mill wide head hot-rolled wide flange sections, the limits detailed details below should be followed.

General Principles
Only YDKT method will be used in the union dimensioning of members. The strength coefficients used for limit situations are:
Ductile failure limit state (Flow Yielding Limit State):
...
Non-ductile Brittle failure limit state (Fracture Boundary Rupture Limit State):
...
Plastic joint hinge length lh is defined in the relevant application rules section for each joint connection type.
Plastic joint hinge moment values:
...
The V- enduc used in the dimensioning of the joint connection is determined according to the equation in the figure above image by summing the shear force determined on the basis of the yield yielding limit state and with the shear force calculated from the combination of 1.2G + 0.5Q + 0.2S on the plastic joint hinge at the end of the beam.
The shear strength required for the shear panel zone is calculated by using the column shear force generated by the possible plastic moments of the beams connecting to the column.
