4.3.3.46 Design of Joint J 12
Joint J 12 (see Figure 4.104 ) can be designed using the same M27 high-
strength pretensioned bolts as follows.

Number of Bolts for the Vertical Member V 6
The member is zero under the applied dead and live load cases of loading.
The number of bolts can be taken as the minimum number based on the
connection drawing. The number of connecting bolts of V 6 is taken as
16 bolts (8 bolts in each side acting in single shear).
