The maximum width of a building designed under Part 4 is 12m where Part 2 can be used for building widths up to 16m and maximum external wall heights are 2.7m and 3m respectively. Part 2 is a lot more complex in relation to bracing calculation and requires the raking forces to be determined and the calculation of bracing expressed in kilo Newtons per metre designed to counter that force. The ACQ treatment process is similar to CCA but is free of arsenic. Decide the direction of the decking boards as the bearer direction is the same as the . The degree of preservative treatment, durability, and hazards/environment in which the timber is used, all play a role in the service life of timber, as outlined in AS 5604, Timber Natural Durability Rating. TABLE 4 - Floor load width 4800 mm. However, AS1684 also provides a lot of information about framing which is why I wondered. Pine that has been treated with CCA is clean, odourless, and has a slight green colour. But you design from the Roof down because loads from above can impact on members below. This span is used to determine the size using the Continuous Span tables. Save on multi-year plans. The scope of Part 4, including house geometry and range of stress grades is also more limited. T3 Green . cantilevers and offsets). Step 1: Determine the wind classification to factor in wind loads. Span tables are not included in this software.

To assess the amount of bracing a building requires under Part 4 only requires four steps, the bracing units are expressed as type A or type B and a simple table will indicate how many units are required. Multinail- Thissoftware has been developed completely in-house since 1980, initially as engineering tools for estimating and detailing, however over the years the focus has changed to incorporate the production of prefabricated trusses from builders plans to the manufacturing plant through to the finished product. thickness as for rafters 50 greater in depth than rafters with thickness as for rafter (min. 1. Table 2 Timber Posts Supporting Roof and/or Floor Loads. The geometric limits of the span tables often will limit these widths. Using AS 1684.2 Span Tables. Explanations and examples are provided. More Information. The Sizer program is also available separately. On some situations it will provide more conservative solutions. Sizing and spans designed according to the applicable span tables in AS1684.2 . The NCC BCA refers to AS1684 but mainly to do with timber stumps and bracing for timber stumps. Some major changes to this edition include amendments to wall nogging requirements, inclusion of ring beam systems and an Appendix of building practices for engineered wood products (EWPs).

Pryda Frame -Designs virtually any structural timber component and calculates the most cost effective sizes of structural beams, joists, roof members, wall plates and studs. Timber Framed Construction Each set of Span Tables contains 53 separate design tables 6. (between the pitching points of the roof, i.e. RLW is the width of roof that contributes roof load to a supporting member. The American Wood Council (AWC) provided technical guidance for CWCs development of the US version. 1) Refer to general notes for information that is relevant for all span tables. AS 1684 SPAN TABLES Roof Framing - Batten Design Typical Process. Ceiling load width (CLW) is the width of ceiling that contributes ceiling load to a supporting member (usually measured horizontally). It refers to a variety of pine that can bear a total pressure of 10,000 MPa in a nutshell. It is widely reported that this software package offers a high level of sophistication in combination with ease of use.

Pine was chosen as a plantation species due to its robustness, excellent growth and versatility of its timber. The term applied to members supported at or near both ends and at one or more intermediate points such that no span is greater than twice another. Typical materials are f7 or mgp10 90mm x 35mm in size. Hyne Timber Design 7.5 includes the engineering properties and span tables for Hyne Timber, Wesbeam, Tilling, Carter Holt Harvey and Louisiana Pacific products. For easy specification Part 4 Simplified Non-cyclonic (N1/N2) has been derived from AS1684.2 and provides simplified design procedures for timber span solutions, bracing and tie-down. FLOOR BEARERS. Step 4: Determine the rafter overhang which creates a cantilever span adding extra load. How should AS 1684 Residential Timber Framed Construction be interpreted for installation of residential timber and which part of the Standard suits your needs? Four wind classifications are covered including N1, N2, N3 and N4. Wesbeam e-house Software- This e-house software suite integrates the activities of design, drafting, specification and engineeringe-house beam sizes individual beams; e-house [floor] is a complete 3D roof and floor design suite; e-house [stick] is a 3D software which integrates and automates the design and engineering of stick roofs; and, e-house [WoH] is a 3D software which integrates and automates all major design elements when specifying and engineering framing environments for wood-framed structures in Australia.
