Table 10 Notes (AS 1684.2:2021)
Maximum roof areas assume total sheet roof (framing + ceiling) mass of 40 kg/m² and tile roof mass of 90 kg/m². Refer to Appendix A for guidance on roof/ceiling mass.
Where studs supporting concentrations of load occur in external walls, they shall be installed in addition to common studs.
For studs supporting hanging beams, use one half of the ceiling area supported by the beam and select from the sheet roof column.
Large stud sizes may be made up by vertical nail lamination per Cl. 2.4.
For design parameters refer to Figure 6.13.
Where studs are used for tie-down, the maximum tension load is 8.5 kN per stud or nail-laminated unit.
NS = Not Suitable for this combination.
