Timber framing code 2008:
Floor Framing.
Specification:• Timber framed construction • Conventional timber framed roof• Roof pitch 22.50• Roof covering steel roof decking, 10kg/m2• Eaves width 600mm• Brick piers supporting bearers• Bearers 150 x 75 Unseasoned
Hardwood, F11• Joists 100 x 50 Unseasoned
Hardwood, F11• Fitted timber floors Utility grade 19mm T&G
Radiata Pine• Wet area flooring 19mm CSR structafloor
particleboard
Remember the following information:
– Type of flooring determines the MAX SPACING of floor joists
– SPAN of joists determines the SPACING of bearers
– SPAN of bearers determines SPACING of piers

Bearers, Clause 4.3.1
• The max span of 1600 for the floor joists will determine the max spacing of the bearers parallel to the building length.
• Determine from the various tables the span for the given bearer size (150x75).
• These spans determine the pier spacings
Bearers supporting load–bearing walls
• RLW = Rafter span + overhang• Rafter run • = 7.470 / 2• Rafter run = 3.735• Rafter length = 3.735 / Cos 22.5o
• Rafter length = 4.042• Overhang =600 / Cos 22.5o
• Overhang =0.649• RLW = 4.042+0.649 = 2.670 2 • RLW = 2.7
FLW Bearers: load bearing walls
• Table one of Supplement 13• Say RLW of 4500 (2700 actual)• FLW = 1600/2 = 800 (based on max joist span)
• Read max bearer span from table 1 for FLW 1200
• Allowable span for 150 x 75 = 1700
Bearers: floor loads only
• Table 5, supplement 13• FLW = ? (Based on max joist span)• FLW = 1600• Go to Table 5 for FLW 1800
• Allowable span of bearer: 150x75 = 2100
Centreline spacing of brick piers
• Supporting load bearing walls This is determined by the span of the
bearer supporting load bearing walls• = span of bearer plus 230 (size of brick
pier)• = 1700 + 230
• = 1930
Centreline spacing of brick piers
• Supporting floor loads only This is determined by the span of the bearer supporting floor loads only.
• Span of bearer plus 230 (size of brick pier)
• = 2330
