    Study Notes

    AS 1684.2-2010: Design Criteria for Timber Framed Structures

    • The maximum width of a building should be 16,000 mm, excluding eaves.

    • The maximum wall height should be 3000 mm (floor to ceiling, as measured at common external walls).

    • The maximum roof pitch should be 35° (70:100).

    • For single or upper storey construction, the spacing of bracing elements should not exceed 9000 mm.

    • Roof construction shall be hip, gable, skillion, cathedral, trussed or pitched, or in any combination of these.

    • Building masses appropriate for the member being designed should be determined prior to selecting and designing from the Span Tables.

    • The design criteria used in the preparation of the Standard are AS 1684.1 and AS 1720.1.

    • Structural timber used in accordance with this Standard should have the level of durability appropriate for the relevant climate and expected service life and conditions.

    • Timber dimensions throughout this Standard are stated by nominating the depth of the member first, followed by its breadth.

    • The minimum bearing for specific framing members should be as given in the Notes to the Span Tables.

    • Fabricated components may be used where their design is in accordance with AS 1720.1 and their manufacture and use complies with the relevant Australian Standards.

    • When using the Span Tables given in the Supplements, certain maximum undersize tolerances on timber sizes are permitted.Design Considerations for Timber Structures According to AS 1684.2-2010

    • The design and corrosion protection of metal components in timber structures must comply with relevant Australian Standards.

    • The minimum corrosion protection for metal straps and framing anchors is Z 275, with a minimum thickness of 0.8mm and net cross-section area of 21mm2.

    • The minimum steel grade for metal straps and framing anchors is G 300, while all other metal components must meet relevant Australian Standards.

    • Prior to using the Standard, the design gust wind speed and corresponding wind classification must be determined, taking into account building height, terrain category, and topographic and shielding effects.

    • The recommended procedure for designing the structural timber framework is to determine the preliminary location and extent of bracing and tie-down, and then the basic frame layout.

    • Individual member sizes are determined by selecting the roof framing timbers and then systematically working through the remainder of the framework to the footings, or by considering the floor framing through to the roof framing.

    • Interpolation must be made in accordance with Appendix C.

    • Ring beams made up of two spaced members must be laminated vertically with additional nails at the point of load or support, and steel bridging plate/washer for tie-down rod.

    • Studs at sides of openings and supporting concentrations of load can be built up using two or more laminations of the same timber type, stress grade, and moisture content condition.

    • Wall plates made up of more than one section must be horizontally nail-laminated with two nails at not greater than 600mm centres along the plate.

    • The supported load width and area are used to define the amount of load that is imparted onto a member, with floor load width (FLW), ceiling load width (CLW), and roof load width (RLW) determined based on construction type.

    • The area supported by a member is the contributory area, measured in either the roof or floor plane, that imparts load onto supporting members, and is used as an input to Span Tables in the Supplements for various members.AS 1684.2-2010: Definitions and Terms for Loadbearing Structures

    • The standard provides definitions for loadbearing and non-loadbearing walls, regulatory authority, roof types, and span and spacing terms.

    • Loadbearing walls support roof or floor loads, while non-loadbearing walls do not support these loads but may act as bracing walls or support lateral wind loads.

    • The regulatory authority is responsible for approving the design and construction of a building or any part of the process.

    • The standard defines four types of roofs: coupled, non-coupled, pitched, and trussed.

    • Coupled roofs have a slope of at least 10°, with ceiling joists and collar ties fixed to opposing common rafter pairs and a ridgeboard at the apex of the roof.

    • Non-coupled roofs are pitched roofs that do not fit the definition of coupled roofs and include cathedral roofs and those constructed using ridge and intermediate beams.

    • Pitched roofs are roofs where members are cut to suit and erected on site.

    • Trussed roofs are engineered roof frame systems designed to carry the roof or roof and ceiling without the support of internal walls.

    • The standard provides terms for spacing, span, single span, and continuous span, with Figure 2.18 illustrating these terms.

    • Spacing is the center-to-center distance between structural members, while span is the face-to-face distance between points capable of giving full support to structural members or assemblies.

    • Rafter spans are measured as the distance between points of support along the length of the rafter and not as the horizontal projection of this distance.

    • The standard also provides calculations for determining the roof and floor area supported by strutting beams, rafter spans, post spacing, and joist spans.
