Regulatory and Consumer Challenges Facing Timber Preservation and Durability Interests in New Zealand and Australia
2003 - IRG/WP 03-20282
Timber preservation and durability interests in Australia and New Zealand are facing many challenges and threats arising from regulation and standards changes, to direct competition from competitive materials producers. Industry can address these challenges by pro-active initiation of sound, holistic, research, that addresses the performance needs of the regulators and specifiers and the expectati...

An engineering model for the decay of timber in ground contact
2003 - IRG/WP 03-20260
To predict the residual strength of an engineered structure, it is first necessary to predict the effect of decay. A model was developed in which the effective area of structural decay in large section timbers was defined as that area that could be picked out with a pen-knife. Some limited studies indicated that for practical purposes the remaining wood could be assumed to have its full residual s...
