1. Finding batten span and rafter spacing of the RL1 area

Wind Classification=N1Batten spacing = 600 mmNo of battens= 6Approximated Batten Span=600 mmBatten span = Rafter Spacing Therefore the rafter spacing= 600 mm

2. Size of window ( Lintel Span) = 2400 mm

3. Determine the Roof Load Width at the selected area

The following equation applies to

RLW =

From the roof framing drawing X = 5400mm,a = 500 mm

Therefore total RLW = 5900mm

4. Using AS 1684.2 Table 17, Stress grade MGP 10

Roof load width = 6000 mmTruss Spacing = 600 mmMaximum lintel span= 2500 mmStandard Lintel size:=2 / 170 35 mm

However we will chose one depth greater than the standard size for wind classification N1 requirement

Selected Lintel size= 2 / 190 35 mm
