BCGCA3004B. Construct Wall Framing. Wall Framing. Building Code of Australia states that All timber framing is to be done in accordance with AS 1682 This is an all encompassing standard which details the allowable construction methods. Wall Frame Members.
Construct Wall Framing
Timbers Generally Used- Radiata Pine- Oregon (Douglas Fir)- Various Hardwood Species
Engineered Timber (LVL) Lintels
Radiata Pine Studs
Engineered Timber (I Beams) Deep Joists
Refer page 187 TAFE Guide
- Common- Door & Window- Secondary Jamb Studs- Jack & Short
Timber Bracing – 50 to 75 mm x 19 to 25mm checked into and nailed flush into face of studs. Braces must be installed in opposing pairs in external bracing walls.
This method is virtually never used today.
Rated 0.8 kN/m
Perforated Metal Bracing- Installed in similar method as timber brace with a saw cut into the plates and studs.
The brace is then nailed flush onto the studs and plates.
Braces must be installed in opposing pairs in external walls.
Rated 0.8 kN/m
Flat Metal or Hoop Iron Bracing
1.4.4 The Maximum number of storey's of timber shall not exceed 2
1.4.5 The maximum width of a building shall 16 000mm, Note, if you use AS1684.2 simplified max width = 12 000mm1.4.6 The maximum wall height shall be 3000mm excluding gable ends
1.4.7 The maximum roof pitch shall be 35 degrees
A3P has announced that it will not proceed with the introduction of Structural Pine (SP) grading as previously planned.
Continuing contact with A3P members, timber merchants, truss and frame fabricators, designers and specifiers has indicated the introduction cannot be achieved without major disruption and unacceptable burden to industry.
Stud Sizes are determined by
Stud Spacing Determined by
Step 1 – Determine Floor & Ceiling
Floor Carpet = 20mm
Ceiling Gyprock = 13mm
Step 2 – Calculate Stud Length
Minimum Clearance = 2400mm
Plus Flooring = 20mm
Plus Ceiling = 20mm
Wall Height = 2440mm
less Wall Plates = 90mm
Stud Length = 2350mm
First Floor = Carpet (20mm)
Upper Level Joists = 200 x 50 F5
Top & Bottom Plates = 90 x 45
Step 1- Determine SFL (Structural Floor Level)
SFL First Floor = 28.950 (FFL First Fl)
SFL Ground Fl = 26.200 (FFL Gnd)
- 40 (Timber)
SFL = 26.160
Step 2 – Calculate Height Difference
SFL First Floor = 28.930 –
SFL Ground Fl = 26.180
Height Difference = 2.750
Height Diff = 2.750
Less Flooring = 0.017
Less Floor Joist = 0.200
Less T & B Plate = 0.090
Stud Length = 2.443
Dimensions are clear measurements
Lower level plates Upper Level Plates
Bottom Plate = 90 x 35 F5 Bottom Plate = 90 x 45 F5
Top Plate = 90 x 45 F5 Top Plate = 90 x 70 F5
