The WoodSolutions Bushfire Calculator V2.1 is an online (not downloadable) design tool developed to assist building designers, builders, regulators and home owners in determining the relevant Bushfire Attack Level (BAL) for a specific building site.

The Design Capacity Tables for Timber is a design aid for structural engineers. It provides assistance in the limit states modelling of timber behaviour.

The majority of timber structures will perform their intended function for their service life with minimal maintenance. However, for this to occur, all the factors that influence the durability of the timber need to be properly considered.

Durability is one of the key performance factors used to assess the suitability of a timber species for a specific application. The durability rating of a species is based on the natural ability of the heartwood of that species to resist decay and insect pests.

Incidence of major damage by termites: An assessment of the amount of damage done to constructions by termites.

The machine stress grading process requires that quality checks be built into the operation of the machine so that its grading is uniform over time, and that the correlation between grading parameter and the properties of the product remains valid. These checks are on the performance of the machine, which can be found by running calibration sticks of known properties through the machine, and on the performance of the output, by periodically performing destructive tests on samples of the graded timber. Quality control gives some indication of the success of the grading, and it is incorporated in the design of timber elements through the use of different capacity factors for different levels.

Changes in building regulations and the banning of effective organochlorine insecticides for soil treatment has meant that new home owners, builders and designers will need to reconsider the ways in which they can effectively prevent termite damage. This document discusses in detail the options available, outlining best practice methods for successful prevention.

Span tables have been prepared for the four species groups (A to D) using the RG1 recycled grade for wind classifications N1 to N3 and C1 to C2.

Span tables and other software resources from industry groups and manufacturers that assist in designing construction in compliance with codes such as AS 1684. Primary design software program includes generic span tables for various building elements (excluding verandah beams) enabling users to select sizes and load conditions to generate suitable member sizes and grades.
