NOTES: i) Maximum spans are based on the support of roof mass only for a coupled roof and the combined roof plus ceiling mass for a cathedral roof. For guidance on roof and ceiling mass refer to Appendix B. ii) Allowable overhangs are based on a maximum depth of birdsmouth of D/3. Refer Figure 7.28. iii) Where rafters are not birdsmouthed, the allowable overhang may be increased to 30% of the allowable single span for that member. Overhang shall not exceed 50% of actual backspan. iv) Overhang limits do not apply where rafter ends are tied back to wall frame. v) Overhang limits are only applicable where rafter ends are supported by a structural fascia board. Refer to Clause 7.3.13.2. vi) Multiple members shall be nailed together as per Clause 2.3. vii) For design parameters refer to Figures 7.26 and 7.27.

NOTES: i) Maximum Lintel Spans are based on the support of a maximum total tile roof, framing and ceiling mass of 90 kg/m 2 and a maximum flooring mass of 40 kg/m2. For guidance on roof and ceiling mass refer to Appendix B. ii) These lintels are not designed to support concentrated loads. iii) Lintels to internal wall openings supporting floor loads only shall be sized as bearers. iv) Lintels in gable or skillion end walls not supporting roof or floor loads shall be determined as per Clause 6.3.6.3. v) Minimum bearing length = 35 mm at end supports. Subscript values indicate the minimum additional bearing length where required to be greater than 35 mm. vi) Multiple members shall be nailed together as per Clause 2.3. viii) For design parameters refer to Figure 6.20(b). ix) Lintels must be used in conjunction with top plates, ledgers and head trimmers. x) When lintels are used to their maximun design limits, deflections of up to 10 mm (deadload) or 15mm (live load) may be expected.

NOTES i) Maximum roof load widths are based on the support of a maximum total sheet roof, framing and ceiling mass of 40 kg/m2. and a maximum tile roof, framing and ceiling mass of 90 kg/m2. For guidance on roof and ceiling mass refer to Appendix B. ii) Studs for internal non-loadbearing bracing walls and partitions (not carrying roof loads) shall be as per Clause 6.3.5. iii) Edge distances for some sheet bracing materials may require a minimum stud width of 45 mm for joining sheets. iv) For gable or skillion end studs (not supporting roof loads) refer Clause 6.3.2.5. v) Large stud sizes may be made up by vertical nail lamination as per Clause 2.4. vi) For design parameters refer to Figure 6.12. vii) All stud walls shall be nogged at not greater than 1350 mm centres. viii) Where studs are used for tie-down, the maximum tension load that can be imparted to the stud is 8.5kN per stud or laminate where they are nail laminated.

NOTES TO TABLE 13: i) Maximum Roof Load Widths are based on the support of a maximum total sheet roof, framing and ceiling mass of 40 kg/m2 and a maximum total tile roof, framing and ceiling mass of 90 kg/m2. For guidance on roof and ceiling mass refer to Appendix B. ii) Studs for internal non-loadbearing bracing walls and partitions (not carrying roof loads) shall be as per Clause 6.3.5. iii) Edge distances for some sheet bracing materials may require a minimum stud width of 45 mm for joining sheets. iv) Jamb studs for opening in internal load bearing walls shall be as per Table 11. v) Large stud sizes may be made up by vertical nail lamination as per Clause 2.4. vi) For design parameters refer to Figure 6.15. vii) Where roof loads are supported only on studs supporting concentrated loads, posts or jamb studs, the internal walls can be classified as non-loadbearing walls. Refer Clause 6.3.5. viii) Notches for diagonal braces shall be as per Clause 6.2.1.4. ix) Where studs are used for tie-down, the maximum tension load that can be imparted to the stud is 8.5kN per stud or laminate where they are nail laminated.

NOTES: i) Maximum Lintel Spans are based on the support of a maximum total sheet roof, framing and ceiling mass of 40 kg/m2. For guidance on roof and ceiling mass refer to Appendix B. ii) For lintels supporting concentrated loads refer Table 20. iii) Lintels to internal wall openings supporting ceiling joist only shall be sized as hanging beams. iv) Lintels in gable or skillion end walls not supporting roof loads shall be determined as per Clause 6.3.6.3. v) Minimum bearing length = 35 mm at end supports. Subscript values indicate the minimum additional bearing length where required to be greater than 35 mm. vi) Multiple members shall be nailed together as per Clause 2.3. vii) For design parameters refer to Figure 6.20. viii) Lintels must be used in conjunction with top plates, ledgers and head trimmers. ix) When lintels are used to their maximum design limits, deflections of up to 10 mm (deadload) or 15mm (live load) may be expected.

NOTES: i) Maximum spans are based on the support of roof mass only up to a maximum sheet roof mass of 20 kg/m2 and tile roof mass of 60 kg/m2 . For guidance on roof and ceiling mass refer to Appendix B. The mass of rafters and underpurlins is accommodated in the span calculations. ii) Where the depth to breadth ratio exceeds 3:1 G.I. strapping or similar restraint to the top edge of the beam is to be provided at the strutting points and at beam ends. Refer to Clause 7.2.26. iii) Beam ends may be chamfered to a minimum depth of 100 mm or 1/3 of the beam depth, which ever is greater. iv) A minimum initial clearance of 25 mm shall be provided at mid-span between the underside of the strutting beam and the tops of ceiling joist, ceiling lining or ceiling battens as appropriate. v) Minimum bearing length = 70 mm at end supports. vi) Multiple members nailed together as per Clause 2.3. vii) For design parameters refer to Figure 7.24.

3/45x90 NOTES: i) Maximum roof load widths are based on the support of a maximum total sheet roof, framing and ceiling mass of 40 kg/m2. For guidance on roof and ceiling mass refer to Appendix A. ii) Where rafters or trusses are supported directly over studs or within 1.5 times the thickness of the top plate from the studs the top plate may be a minimum 35 mm deep. iii) Where plates support concentrated loads such as roof beams, struts, strutting beams, hanging beams, counter beams, combined strutting/hanging beams or girder trusses etc., the load shall be supported directly over a stud(s) designed to carry the load or the plate stiffened in accordance with Clause 6.2.2.3. iv) Plates may be trenched up to a maximum of 3 mm for studs. v) Multiple plates shall be nailed together as per Clause 2.5. vi) For design parameters refer to Figure 6.19. vii) Where wind uplift forces on rafters or trusses are taken to the substructure, bypassing the top plate, the top plate size may be determined using the tie-down spacing of “0” in the table.

NOTES: i) Maximum spans are based on the support of roof mass only for a coupled roof and the combined roof plus ceiling mass for a cathedral roof. For guidance on roof and ceiling mass refer to Appendix A. ii) Allowable overhangs are based on a maximum depth of birdsmouth of D/3. Refer Figure 7.28. iii) Where rafters are not birdsmouthed, the allowable overhang may be increased to 30% of the allowable single span for that member. Overhang shall not exceed 50% of actual backspan. iv) Overhang limits do not apply where rafter ends are tied back to wall frame. v) Overhang limits are only applicable where rafter ends are supported by a structural fascia board. Refer to Clause 7.3.13.2. vi) Multiple members shall be nailed together as per Clause 2.3. vii) For design parameters refer to Figures 7.26 and 7.27.

For guidance on roof and ceiling mass refer to Appendix A. ii) For lintels supporting hanging beams, the area supported shall be taken as one half of the ceiling area supported by the lintel and the size determined from the sheet roof section. iii) Minimum bearing length = 35 mm at end supports. Subscript values, where applicable, indicate the minimum additional bearing length where required to be greater than 35 mm. iv) Multiple members nailed together as per Clause 2.3. v) For roof area supported refer Clause 2.6.5. vi) Lintels must be used in conjunction with top plates, ledgers and head trimmers. vii) When lintels are used to their maximum design limits, deflections of up to 10 mm (deadload) or 15mm (live load) may be expected. viii) The roof area supported by the lintel should only be that proportion of roof area contributing to the concentrated load on the lintel, ie the roof area input for a lintel supporting a strutting beam should be proportioned according to the area distributed to either end of the strutting beam.

NOTES: i) Maximum spans are based on the support of roof mass only up to a maximum sheet roof mass of 20 kg/m2 and tile roof mass of 60 kg/m2. For guidance on roof and ceiling mass refer to Appendix B. The mass of rafters and underpurlins is accommodated in the span calculations. ii) Where the depth to breadth ratio exceeds 3:1 G.I. strapping or similar restraint to the top edge of the beam is to be provided at the strutting points and at beam ends. Refer to Clause 7.2.26. iii) Beam ends may be chamfered to a minimum depth of 100 mm or 1/3 of the beam depth, which ever is greater. iv) A minimum initial clearance of 25 mm shall be provided at mid-span between the underside of the strutting beam and the tops of ceiling joist, ceiling lining or ceiling battens as appropriate. v) Minimum bearing length = 70 mm at end supports. vi) Multiple members nailed together as per Clause 2.3. vii) For design parameters refer to Figure 7.24.

NOTES: i) Maximum Roof Load Widths are based on the support of a maximum total sheet roof, framing and ceiling mass of 40 kg/m2 and a maximum total tile roof, framing and ceiling mass of 90 kg/m2. For guidance on roof and ceiling mass refer to Appendix B. ii) Studs for internal non-loadbearing bracing walls and partitions (not carrying roof loads) shall be as per Clause 6.3.5. iii) Edge distances for some sheet bracing materials may require a minimum stud width of 45 mm for joining sheets. iv) Jamb studs for opening in internal load bearing walls shall be as per Table 11. v) Large stud sizes may be made up by vertical nail lamination as per Clause 2.4. vi) For design parameters refer to Figure 6.15. vii) Where roof loads are supported only on studs supporting concentrated loads, posts or jamb studs, the internal walls can be classified as non-loadbearing walls. Refer Clause 6.3.5. viii) Notches for diagonal braces shall be as per Clause 6.2.1.4. ix) Where studs are used for tie-down, the maximum tension load that can be imparted to the stud is 8.5kN per stud or laminate where they are nail laminated.

NOTES: i) Maximum spans are based on the support of a maximum ceiling mass of 12 kg/m2 . For guidance on roof and ceiling mass refer to Appendix B. The mass of ceiling joists and hanging beams is accommodated in the span calculations. ii) Beam ends may be chamfered to a minimum depth of 100 mm or 1/3 of the beam depth, whichever is greater. iii) Where hanging beam spans are not the same each side of the counter beam, the average of the spans may be used. iv) Minimum bearing length = 70 mm at end supports. v) Multiple members nailed together as per Clause 2.3. vi) For design parameters refer to Figure 7.21.

NOTES: i) Maximum spans are based on the support of roof mass only up to a maximum sheet roof mass of 20 kg/m2 and tile roof mass of 60 kg/m2 . For guidance on roof and ceiling mass refer to Appendix B. The mass of rafters and underpurlins is accommodated in the span calculations. ii) Where the depth to breadth ratio exceeds 3:1 G.I. strapping or similar restraint to the top edge of the beam is to be provided at the strutting points and at beam ends. Refer to Clause 7.2.26. iii) Beam ends may be chamfered to a minimum depth of 100 mm or 1/3 of the beam depth, which ever is greater. iv) A minimum initial clearance of 25 mm shall be provided at mid-span between the underside of the strutting beam and the tops of ceiling joist, ceiling lining or ceiling battens as appropriate. v) Minimum bearing length = 70 mm at end supports. vi) Multiple members nailed together as per Clause 2.3. COPYRIGHT vii) For design parameters refer to Figure 7.24.

NOTES TO TABLE 12: i) Maximum Roof Load Widths are based on the support of a maximum total sheet roof, framing and ceiling mass of 40 kg/m2 and a maximum total tile roof, framing and ceiling mass of 90 kg/m2. For guidance on roof and ceiling mass refer to Appendix B. ii) Studs for internal non-loadbearing bracing walls and partitions (not carrying roof loads) shall be as per Clause 6.3.5. iii) Edge distances for some sheet bracing materials may require a minimum stud width of 45 mm for joining sheets. iv) Jamb studs for opening in internal load bearing walls shall be as per Table 10. v) Large stud sizes may be made up by vertical nail lamination as per Clause 2.4. vi) For design parameters refer to Figure 6.1.4. vii) Where roof loads are supported only on studs supporting concentrated loads, posts or jamb studs, the internal walls can be classified as non-loadbearing walls. Refer Clause 6.3.5. viii) Where studs are used for tie-down, the maximum tension load that can be imparted to the stud is 8.5kN per stud or laminate where they are nail laminated.

NOTES: i) Maximum spans are based on the support of roof mass only up to a maximum sheet roof mass of 20 kg/m2 and tile roof mass of 60 kg/m2 . For guidance on roof and ceiling mass refer to Appendix B. The mass of rafters and underpurlins is accommodated in the span calculations. ii) Where the depth to breadth ratio exceeds 3:1 G.I. strapping or similar restraint to the top edge of the beam is to be provided at the strutting points and at beam ends. Refer to Clause 7.2.26. iii) Beam ends may be chamfered to a minimum depth of 100 mm or 1/3 of the beam depth, which ever is greater. iv) A minimum initial clearance of 25 mm shall be provided at mid-span between the underside of the strutting beam and the tops of ceiling joist, ceiling lining or ceiling battens as appropriate. v) Minimum bearing length = 70 mm at end supports. COPYRIGHT vi) Multiple members nailed together as per Clause 2.3. vii) For design parameters refer to Figure 7.24.

NOTES TO TABLE 13: i) Maximum Roof Load Widths are based on the support of a maximum total sheet roof, framing and ceiling mass of 40 kg/m2 and a maximum total tile roof, framing and ceiling mass of 90 kg/m2. For guidance on roof and ceiling mass refer to Appendix B. ii) Studs for internal non-loadbearing bracing walls and partitions (not carrying roof loads) shall be as per Clause 6.3.5. iii) Edge distances for some sheet bracing materials may require a minimum stud width of 45 mm for joining sheets. iv) Jamb studs for opening in internal load bearing walls shall be as per Table 11. v) Large stud sizes may be made up by vertical nail lamination as per Clause 2.4. vi) For design parameters refer to Figure 6.15. vii) Where roof loads are supported only on studs supporting concentrated loads, posts or jamb studs, the internal walls can be classified as nonloadbearing walls. Refer Clause 6.3.5. viii) Notches for diagonal braces shall be as per Clause 6.2.1.4. ix) Where studs are used for tie-down, the maximum tension load that can be imparted to the stud is 8.5kN per stud or laminate where they are nail laminated.

NOTES: i) Maximum spans are based on the support of a maximum sheet roof mass of 20 kg/m2 plus a ceiling mass of 12 kg/m2 and a maximum tile roof mass of 60 kg/m2 plus a ceiling mass of 12 kg/m2 . For guidance on roof and ceiling mass refer to Appendix B. The mass of rafters, underpurlins and ceiling joistsetc. is accommodated in the span calculations. ii) Where the depth to breadth ratio exceeds 3:1, G.I. strapping or similar restraint is to be provided to the top edge of the beam at beam ends. Refer to Clause 7.2.26. iii) Beam ends may be chamfered to a minimum depth of 100 mm or 1/3 of the beam depth, whichever is greater. iv) Where hanging beam spans are not the same each side of the strutting/counter beam, the average of the spans may be used. v) Minimum bearing length = 70 mm at end supports. vi) Multiple members nailed together as per Clause 2.3. vii) For design parameters refer to Figure 7.22.

NOTES i) Maximum Roof Load Widths are based on the support of a maximum total sheet roof, framing and ceiling mass of 40 kg/m2 and a maximum total tile roof, framing and ceiling mass of 90 kg/m2. For guidance on roof and ceiling mass refer to Appendix B. ii) Studs for internal non-loadbearing bracing walls and partitions (not carrying roof loads) shall be as per Clause 6.3.5. iii) Edge distances for some sheet bracing materials may require a minimum stud width of 45 mm for joining sheets. iv) Jamb studs for opening in internal load bearing walls shall be as per Table 10. v) Large stud sizes may be made up by vertical nail lamination as per Clause 2.4. vi) For design parameters refer to Figure 6.1.4. vii) Where roof loads are supported only on studs supporting concentrated loads, posts or jamb studs, the internal walls can be classified as non-loadbearing walls. Refer Clause 6.3.5. viii) Where studs are used for tie-down, the maximum tension load that can be imparted to the stud is 8.5kN per stud or laminate where they are nail laminated. COPYRIGHT

NOTES: i) Maximum roof load widths are based on the support of a maximum total sheet roof, framing and ceiling mass of 40 kg/m2. For guidance on roof and ceiling mass refer to Appendix A. ii) Where rafters or trusses are supported directly over studs or within 1.5 times the thickness of the top plate from the studs the top plate may be a minimum 35 mm deep. iii) Where plates support concentrated loads such as roof beams, struts, strutting beams, hanging beams, counter beams, combined strutting/hanging beams or girder trusses etc., the load shall be supported directly over a stud(s) designed to carry the load or the plate stiffened in accordance with Clause 6.2.2.3. iv) Plates may be trenched up to a maximum of 3 mm for studs. v) Multiple plates shall be nailed together as per Clause 2.5. vi) For design parameters refer to Figure 6.19. vii) Where wind uplift forces on rafters or trusses are taken to the substructure, bypassing the top plate, the top plate size may be determined using the tie-down spacing of “0” in the table.

For guidance on roof and ceiling mass refer to Appendix A. The mass of rafters and underpurlins is accommodated in the span calculations. ii) Where the depth to breadth ratio exceeds 3:1 G.I. strapping or similar restraint to the top edge of the beam is to be provided at the strutting points and at beam ends. Refer to Clause 7.2.26. iii) Beam ends may be chamfered to a minimum depth of 100 mm or 1/3 of the beam depth, which ever is greater. iv) A minimum initial clearance of 25 mm shall be provided at mid-span between the underside of the strutting beam and the tops of ceiling joist, ceiling lining or ceiling battens as appropriate. v) Minimum bearing length = 70 mm at end supports. vi) Multiple members nailed together as per Clause 2.3. vii) For design parameters refer to Figure 7.24.

For guidance on roof and ceiling mass refer to Appendix A. ii) For lintels supporting hanging beams, the area supported shall be taken as one half of the ceiling area supported by the lintel and the size determined from the sheet roof section. iii) Minimum bearing length = 35 mm at end supports. Subscript values, where applicable, indicate the minimum additional bearing length where required to be greater than 35 mm. iv) Multiple members nailed together as per Clause 2.3. v) For roof area supported refer Clause 2.6.5. vi) Lintels must be used in conjunction with top plates, ledgers and head trimmers. vii) When lintels are used to their maximum design limits, deflections of up to 10 mm (deadload) or 15mm (live load) may be expected. viii) The roof area supported by the lintel should only be that proportion of roof area contributing to the concentrated load on the lintel, ie the roof area input for a lintel supporting a strutting beam should be proportioned according to the area distributed to either end of the strutting beam.

For guidance on roof and ceiling mass refer to Appendix A. The mass of rafters and underpurlins is accommodated in the span calculations. ii) Where the depth to breadth ratio exceeds 3:1 G.I. strapping or similar restraint to the top edge of the beam is to be provided at the strutting points and at beam ends. Refer to Clause 7.2.26. iii) Beam ends may be chamfered to a minimum depth of 100 mm or 1/3 of the beam depth, which ever is greater. iv) A minimum initial clearance of 25 mm shall be provided at mid-span between the underside of the strutting beam and the tops of ceiling joist, ceiling lining or ceiling battens as appropriate. v) Minimum bearing length = 70 mm at end supports. vi) Multiple members nailed together as per Clause 2.3. vii) For design parameters refer to Figure 7.24.

For guidance on roof and ceiling mass refer to Appendix A. ii) For lintels supporting hanging beams, the area supported shall be taken as one half of the ceiling area supported by the lintel and the size determined from the sheet roof section. iii) Minimum bearing length = 35 mm at end supports. Subscript values, where applicable, indicate the minimum additional bearing length where required to be greater than 35 mm. iv) Multiple members nailed together as per Clause 2.3. v) For roof area supported refer Clause 2.6.5. vi) Lintels must be used in conjunction with top plates, ledgers and head trimmers. vii) When lintels are used to their maximum design limits, deflections of up to 10 mm (deadload) or 15mm (live load) may be expected. viii) The roof area supported by the lintel should only be that proportion of roof area contributing to the concentrated load on the lintel, ie the roof area input for a lintel supporting a strutting beam should be proportioned according to the area distributed to either end of the strutting beam.

NOTES: i) Maximum spans are based on the support of roof mass only up to a maximum sheet roof mass of 20 kg/m2 and tile roof mass of 60 kg/m2 . For guidance on roof and ceiling mass refer to Appendix B. The mass of rafters and underpurlins is accommodated in the span calculations. ii) Where the depth to breadth ratio exceeds 3:1 G.I. strapping or similar restraint to the top edge of the beam is to be provided at the strutting points and at beam ends. Refer to Clause 7.2.26. iii) Beam ends may be chamfered to a minimum depth of 100 mm or 1/3 of the beam depth, which ever is greater. iv) A minimum initial clearance of 25 mm shall be provided at mid-span between the underside of the strutting beam and the tops of ceiling joist, ceiling lining or ceiling battens as appropriate. v) Minimum bearing length = 70 mm at end supports. vi) Multiple members nailed together as per Clause 2.3. vii) For design parameters refer to Figure 7.24.

NOTES TO TABLE 29: i) Maximum spans are based on the support of roof mass only for a coupled roof and the combined roof plus ceiling mass for a cathedral roof. For guidance on roof and ceiling mass refer to Appendix B. ii) Allowable overhangs are based on a maximum depth of birdsmouth of D/3. Refer Figure 7.28. iii) Where rafters are not birdsmouthed, the allowable overhang may be increased to 30% of the allowable single span for that member. Overhang shall not exceed 50% of actual backspan. iv) Overhang limits do not apply where rafter ends are tied back to wall frame. v) Overhang limits are only applicable where rafter ends are supported by a structural fascia board. Refer to Clause 7.3.13.2. vi) Multiple members shall be nailed together as per Clause 2.3. vii) For design parameters refer to Figures 7.26 and 7.27.

NOTES: i) Battens are not suitable for the support of construction loads prior to fixing of the roof cladding. ii) The roof batten sizes determined from the above table accommodate local wind pressure effects near edges of roofs for tile roofs. For sheet roofs, to accommodate local pressure, battens within 1200 mm of edges (hips, ridges, fascias and barges) shall have their spacing reduced by 25% from the tabulated value or alternatively, the breadth of the batten shall be increased by 25%. iii) Allowable spans and overhangs are based on a maximum Sheet Roof Mass of 10 kg/m2 and Tile Roof Mass of 60 kg/m2. Overhangs shall not exceed 50% of actual backspan. iv) For guidance on roof and ceiling mass refer to Appendix B. v) For design parameters refer to Figure 7.30.

NOTES i) Maximum Roof Load Widths are based on the support of a maximum total sheet roof, framing and ceiling mass of 40 kg/m2 and a maximum total tile roof, framing and ceiling mass of 90 kg/m2. For guidance on roof and ceiling mass refer to Appendix B. ii) Studs for internal non-loadbearing bracing walls and partitions (not carrying roof loads) shall be as per Clause 6.3.5. iii) Edge distances for some sheet bracing materials may require a minimum stud width of 45 mm for joining sheets. iv) Jamb studs for opening in internal load bearing walls shall be as per Table 10. v) Large stud sizes may be made up by vertical nail lamination as per Clause 2.4. vi) For design parameters refer to Figure 6.1.4. vii) Where roof loads are supported only on studs supporting concentrated loads, posts or jamb studs, the internal walls can be classified as non-loadbearing walls. Refer Clause 6.3.5. viii) Where studs are used for tie-down, the maximum tension load that can be imparted to the stud is 8.5kN per stud or laminate where they are nail laminated. COPYRIGHT

NOTES: i) Maximum spans are based on the support of roof mass only for a coupled roof and the combined roof plus ceiling mass for a cathedral roof. For guidance on roof and ceiling mass refer to Appendix A. ii) Allowable overhangs are based on a maximum depth of birdsmouth of D/3. Refer Figure 7.28. iii) Where rafters are not birdsmouthed, the allowable overhang may be increased to 30% of the allowable single span for that member. Overhang shall not exceed 50% of actual backspan. iv) Overhang limits do not apply where rafter ends are tied back to wall frame. v) Overhang limits are only applicable where rafter ends are supported by a structural fascia board. Refer to Clause 7.3.13.2. vi) Multiple members shall be nailed together as per Clause 2.3. vii) For design parameters refer to Figures 7.26 and 7.27. (viii) Minimum bearing length = 35 mm at end supports and 70 mm at internal supports for continuous members. Subscript values, where applicable, indicate the minimum additional bearing length where required to be greater than 35 mm at end supports and 75 mm at internal supports.

For guidance on roof and ceiling mass refer to Appendix A. ii) For lintels supporting concentrated loads refer Table 20. iii) Lintels to internal wall openings supporting ceiling joist only shall be sized as hanging beams. iv) Lintels in gable or skillion end walls not supporting roof loads shall be determined as per Clause 6.3.6.3. v) Minimum bearing length = 35 mm at end supports. Subscript values, where applicable, indicate the minimum additional bearing length where required to be greater than 35 mm. vi) Multiple members shall be nailed together as per Clause 2.3. vii) For design parameters refer to Figure 6.20. viii) Lintels must be used in conjunction with top plates, ledgers and head trimmers. ix) When lintels are used to their maximum design limits, deflections of up to 10 mm (deadload) or 15mm (live load) may be expected.

NOTES: i) Maximum spans are based on the support of roof mass only up to a maximum sheet roof mass of 20 kg/m2 and tile roof mass of 60 kg/m2 . For guidance on roof and ceiling mass refer to Appendix B. The mass of rafters and underpurlins is accommodated in the span calculations. ii) Where the depth to breadth ratio exceeds 3:1 G.I. strapping or similar restraint to the top edge of the beam is to be provided at the strutting points and at beam ends. Refer to Clause 7.2.26. iii) Beam ends may be chamfered to a minimum depth of 100 mm or 1/3 of the beam depth, which ever is greater. iv) A minimum initial clearance of 25 mm shall be provided at mid-span between the underside of the strutting beam and the tops of ceiling joist, ceiling lining or ceiling battens as appropriate. v) Minimum bearing length = 70 mm at end supports. vi) Multiple members nailed together as per Clause 2.3. vii) For design parameters refer to Figure 7.24.

NOTES: i) Maximum spans are based on the support of roof mass only up to a maximum sheet roof mass of 20 kg/m2 and tile roof mass of 60 kg/m2 . For guidance on roof and ceiling mass refer to Appendix B. The mass of rafters and underpurlins is accommodated in the span calculations. ii) Where the depth to breadth ratio exceeds 3:1 G.I. strapping or similar restraint to the top edge of the beam is to be provided at the strutting points and at beam ends. Refer to Clause 7.2.26. iii) Beam ends may be chamfered to a minimum depth of 100 mm or 1/3 of the beam depth, which ever is greater. iv) A minimum initial clearance of 25 mm shall be provided at mid-span between the underside of the strutting beam and the tops of ceiling joist, ceiling lining or ceiling battens as appropriate. v) Minimum bearing length = 70 mm at end supports. COPYRIGHT vi) Multiple members nailed together as per Clause 2.3. vii) For design parameters refer to Figure 7.24.

NOTES: i) Battens are not suitable for the support of construction loads prior to fixing of the roof cladding. ii) The roof batten sizes determined from the above table accommodate local wind pressure effects near edges of roofs for tile roofs. For sheet roofs, to accommodate local pressure, battens within 1200 mm of edges (hips, ridges, fascias and barges) shall have their spacing reduced by 25% from the tabulated value or alternatively, the breadth of the batten shall be increased by 25%. iii) Allowable spans and overhangs are based on a maximum Sheet Roof Mass of 10 kg/m2 and Tile Roof Mass of 60 kg/m2 . Overhangs shall not exceed 50% of actual backspan. iv) For guidance on roof and ceiling mass refer to Appendix B. v) For design parameters refer to Figure 7.30.
