1 Timber Wall Framing Class Exercise 2

2 Reference Material A.S. 1684.2 (2006) Non Cyclonic

3 Details: Floor Plan – Same as Roofing Class Exercise 2 Brick Veneer Construction Roof Pitch 18 0 Cement Tile Roofing 60Kg/m 2 Eaves Width 600mm Floor to Ceiling Height 2.700m Wall Framing – Seasoned Softwood MGP 15 Concrete Raft Floor Slab Wind Classification – N3

4 Wall Frame. (Supporting Conventional Roof Framing) Determine the most economical size, span & spacing of the following members 1.Bottom Wall plate – not trenched. 2.Top Wall plate – not trenched (to support rafters @ 600mm c/c) 3.Common Studs at 600mm c/c (not notched for erection bracing) 4.Noggings 5.Jamb Studs (studs at sides of openings) 6.Lintels 7.Eaves Beams (Verandah Beams) 8.Tie down spacing 1.800

5 Use Preliminary Calculations from Roofing exercise 2. Summary RLW Rafter = 2.064 say 2.100 RLW Eaves = 0.788 Purlin Set out = 1.872 Half spread fan strut = 0.671 Fan Strut Length = 0.931
