(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). The welds must be designed according to the shear force acting on continuity plates.

9.3.4.3 - In beam-column connection details that transfer moment, continuity plates will be placed on both sides of the column web at the level of beam flanges and by this, it will be ensured that the tensile and compressive forces on the beam flanges are transferred to the column (and to the neighbouring beam in beam-column connection) (Figure 9.3).
(a) Thethickness of the continuity plates shall not be less than the flange thickness of the assembling beam in one-sided beam joints, and in the case of two-beams assembling assembled to the column from both sides, the thickness of the flange continuity plates should not be less than the greatest thickness of the flanges of the connected beams shall not be less.
(b) Full penetration groove weld will be used to assemble the continuity plates to the column web and flanges. Fillet weld can also be used to assemble the continuity plate to the column web. However, this weld should 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 web.
