AS 1684 Residential Timber Framed Construction has four parts: . Part 1 relates to design criteria that can be used as a basis for the preparation of span tables and design data for the other parts. This is the document commonly used by engineers ; The other three parts provide building practices and procedures that assist in the correct specification and determination.

Span For the purpose of using these tables, span may be interpreted as the clear distance between supports measured along the beam. Single Span Beams are beams supported at two points only. Continuous Span Beams are beams supported at three or more points along their length. Continuous span values given in the tables should only be used where: Span tables allow users to choose an appropriate size and stress grade to achieve spanning needs. For simple construction, such as domestic construction, this can be determined from span table supplements in AS1684.2 and AS1684.3. Below we have included common product span tables for: Deck joists ; Floor bearers ; Floor joists ; Upper lintels Span Table Notes i. These tables assume the building practice contained in AS1684 - 2006 - Residential Timber Framing Construction and should be read in conjunction with that standard. ii. Check available joist and bearer lengths with your supplier before specifying. iii. The following table provides an easy comparison of popular seasoned softwood grades and sizes for joists in. iii Joists crippled over supports shall be considered as single span joists.

2) For design parameters, refer to figure 7.26. AS1684.2 and 3. 3) Where rafters are equal to or exceed four times their breath, blocking should be used to reduce distortion. Pergola Beam Spands. Wind Classification 1 & N2. Notes: 1) Refer to general notes for information that is relevant for all span tables. 2) * denotes 600 mm rafter spacing. vii Where joist depth is more than 4 times greater than breadth, restraint may be required. Refer AS1684.2 or AS1684.3 Cl. 4.2.2.3. viii Bearing lengths shall be a minimum of 35 mm at end supports and 70 mm at internal supports for continuous members. ix Continuous indicates continuous members, i.e. where the joists span over 3 or more bearers.

Tables given in Appendix A. The Span Tables for joists and bearers are also suitable for decks up to 1 m above ground. For decks over 1 m above ground (see AS 1684.2). 4.3.2 Bearers . 4.3.2.1 Bearers supporting loadbearing walls . The size of bearers supporting single- or upper-storey loadbearing walls shall be determined from Span Tables A3 to. predominately available in F7 stress grade however F5 and MGP10 are available is some regions. The correct bearer sizes can be found in span Table 49 in AS1684. These tables assume a minimum end bearing of 50 mm by bearer width, and intermediate bearing of 100 mm by bearer width for conti nuous bearers.

The AS 1684 span tables mgp10 provide information on the maximum allowable spans for pergolas based on the size and spacing of the timber. Building Supplements . Building supplements are products that can be used to improve the strength and durability of timber structures. These supplements include preservatives, fire retardants, and sealers.

This is a Supplement to AS 1684.2-2010 and AS 1684.2:2021; Residential timber-framed construction - Part 2: Non-cyclonic areas. The Supplement provides timber framing span tables for wind classification N1/N2 for seasoned softwood - Stress Grade MGP 10. Member span is not suitable for rafter spacing greater than 600 mm. 3. For design parameters, refer to Figure 6.22, AS1684.2 and 3. 4. For the pergola beams shown in illustration, the Roof Load Width is the dimension representing half the rafter span plus any rafter overhang. Refer to AS1684.2 and 3 Clause 2.6.4 for other configurations. 5.
