Consider the brace connection in Figure 4. (a) Design number of required M16 bolts to carry the full tensile capacity of the 2PFC100 section considering the gross area only, i.e., the tensile load for designing the bolts is Ag×fy, where Ag is the gross area of the 2PFC100 section and fy is its yield stress. All the bolts are from bolting category 8.3/TB. In this design consider the shear capacity of the bolts only. Figure 1(a) shows the arrangement and spaces between the bolts. Note that the number of bolts shown in this figure does not show the required number of bolts. Assume that all shear plane bolts have threads. It is assumed that the plate has adequate bearing capacity. (b) If instead of bolts in section (a), as Figure 1(b) shows, a fillet weld with an equal leg of size 6 mm is used to carry the tensile load calculate the required weld length, Lw. Each PFC section is welded by two weld lines to the gusset plate. Therefore, there are four lines to transfer the tensile load from the double section to the gusset plate. The manual metal arc (AS/NZS 4855) with B-E49XX is used for welding. Assume that the weld quality is GP.
