  1. Conventional Roof Framing Class Exercise 1 - 300 Residential Studies Certificate IV 2182D

  2. Using the Floor Plan & Details provided complete the Preliminary Calculations so that the most economical Size, Span and Spacing Of the Ceiling and Roof members can be achieved.

  3. Floor Plan Class Exercise 1 Note: Hyspan LVL Strutting Beams to Living/Family & Living/Dining rooms as shown

  4. Preliminary Calculations Common Rafter True Length of Common Rafter Pitch 300 Half Span = 7.570 – 0.150 2 = 3.635m Rise = 30 Tan x 3.635 = 2.099m TLCR = 4.197 Rise 2.099 TLCR = 3.635 30cos = 4.197m 300 Half Span 3.635

  5. Calculate Common Rafter Span - RLW 2.098 4.197 2.098 RLW = 4.197 2 = 2.098m RLW = 2.098m Say 2.100m

  6. Calculate Eaves Overhang – Eaves RLW TL O/Hang = 0.450 + 0.150 COS 30 = 0.693m 0.693m RLW Eaves = 0.693m 0.150 0.450

  7. Strut = Calculate Fan Struts 2.1 2.098 Strut = Tan30 x 2.098 = 1.211 2.098 0.693 Strut 1.211

  8. Calculate Fan Strut Length 1.211 1.211 Fan Strut =  1.2112 + 1.2112 = 1.713m or = 1.211 cos 45 = 1.713m 1.211 1.713 1.713 Half Spread Fan Strut = 1.211m Fan Strut Length = 1.713m

  9. Calculate Distance X. 2.098 2.098 0.693 Run of rafter = 3.635 Distance X is the distance From the inside of the plate to the centre of the underpurlin. The Formula is Run of rafter divided by 2 minus the width of the wall plate 3.635 / 2 = 1.818 1.818 – 90 = 1728

  10. Summary: Rafter Span = 2.098 Say 2.100 RLW Underpurlin = 2.1 Eaves Overhang = 0.693 Distance X = 1.728 Half spread of the fan strut = 1.211 Full spread of the fan strut = 2.422 Length of strut = 1.713
