Design life for wood and wood-based products

TRADA image

The use of mass timber construction can result in environmental and cost-saving advantages. This research summary examines how the service life of wood products is based on different and complex interactions between end use and interacting or degrading parameters.

Assessment and repair of structural timbernavigation-arrow

Repairs become necessary when a building is no longer safe or serviceable for its intended purpose, or to restore or improve its appearance, performance or function.

 

Timber structures can be repaired using traditional all-timber methods, mechanical fasteners and adhesives, but only following survey and assessment that take account of...

Non-destructive testing of timbernavigation-arrow

Non-destructive testing (NDT) may be defined as 'any means of determining the properties of a material, without causing significant changes to those properties'. This definition permits some degree of damage, providing the performance of the material, in this case timber, is not affected.

Moisture in timbernavigation-arrow

One of the most important factors affecting the performance and properties of wood is its moisture content. The amount of water present in wood can affect its weight, strength, workability, susceptibility to biological attack and dimensional stability in a particular end use.

We estimate that over 80% of...
