In determining the required bending moment strength, the contribution of the additional bending moment from gravity loads for the part of the beam between the plastic hinge and the column face must be taken into account.
(c) To determine the Vuuc, the shear flow mechanism is taken into account to determine shear forces due to gravity resulting from (1.2 G +0.5 Q +0.2 S) combination and shear due to formation of the plastic hinge at beam end or column face by Eq. (9.12).

(b) The smallest thickness of the column doubler plates and if used each of the continuity plates, shall meet the condition tmin ≥ u / 180 (Figure 9.4). In cases where this condition is not fulfilled, the continuity plates and the column doubler plate will be welded to each other so that they work together and it will be checked that the sum of plate thicknesses meets the condition ∑ t ≥ u / 180.
(c) If doubler continuity plates are used in the panel zone, full penetration groove weld or fillet weld shall be used to connect these plates to the column flanges (Figure 9.4). These The welds will be dimensioned by taking into account must be designed according to the shear force borne by the reinforcement plateacting on continuity plates.

9.3.4.3 - In beam-column joint connection details that transfer momentum moment, continuity plates will be placed on both sides of the column body web at the level of beam headsflanges and by this, and it will be ensured that the tensile and pressure compressive forces on the beam heads flanges are transferred to the column (and to the neighboring neighbouring beam in bilateral beam-column jointsconnection) (Figure 9.3).
(a) Thethickness of the continuity plates shall not be less than the head flange thickness of the joining assembling beam in one-sided beam joints, and in the case of beam joining two-beams assembled to the column from both sides, the thickness of the continuity plates should not be less than the greatest thickness of the headers flanges of the joining connected beams shall not be less.
(b) Full penetration butt welding groove weld will be used for to assemble the connection of the continuity plates to the column bodies web and headsflanges. Corner welding Fillet weld can also be used for to assemble the connection of the continuity plate to the column bodyweb. However, this weld should be of have sufficient the length and thickness to transfer a force equal to the shear capacity of the continuity plate in its own plane to the column bodyweb.
(c) Column head flange thickness

Continuity plate may is not be required if both conditions meet.
9.3.4.4 - InFor the dimensioning of the beam-column connection detail, the calculation computation principles given in Annex 9B will be used.
