weld size for fin plate shear connection

Hi,

There is a RAM connection problem about shear connection.

In beam to column web single plate shear connection, the shear is 234.4KN, no axial force, and connecting element material is Q345B, the weld size 8mm is enough to take the shear force shown in the output data, but there have a structure requirement fails, shown in the below,

is this check necessary? or where is it from?

    Shear plate (Support side)

        Weld size                                                                        [mm]                          8               12.00                     --              1

         s = 0.6*t_p/0.7 = 0.6*14[mm]/0.7 = 12[mm]
