Towards a microactuator-sensing network for the structural health monitoring of wood
2023 - IRG/WP 23-50380
Timber structures decay over time with degradation in their structural integrity. Changing environmental conditions, varying loads, exposure to moisture or insect attacks lead to changes in their vibrational response behaviour. Here we present a low-cost device used as a triggered exciter to enable the monitoring of the structural integrity of timber bearers or even power poles in electricity netw...

End-of-life options for engineered wood products / Treated timber in a circular economy
2023 - IRG/WP 23-50383
Australians are excellent consumers of products. These products ultimately end up as waste materials and need to go somewhere. Australia produces around 28 million tons of waste per year with around 50% currently ending up in landfill, including a significant amount of timber, engineered wood products (EWP’s), and preservative treated wood (PTW). Limited landfill capacity, increasing costs, and ...

Australian timber durability research needs
2023 - IRG/WP 23-50385
Australia was once a world leader in timber durability research, but prolonged disinvestment resulted in a gradual decline in capacity. Forest and Wood Products Australia recognized this problem and supported the development of the Centre for Timber Durability and Design Life to help reverse this decline and begin to educate the next generation of Australian researchers. The Centre is a collabor...

On the use of miniaturized wood specimens in fungal decay experiments – mini-blocks versus EN 113 test specimens
2024 - IRG/WP 24-11044
Preliminary evaluation and classification of wood durability against decay fungi using laboratory monoculture experiments has been a longstanding practice because these tests offer quicker results than field tests. Various methods, including miniaturized specimen formats and different incubation periods, have been explored to expedite decay processes and assess wood preservation efficacy. The 'min...

Surface treatment of cross-laminated timber to improve water repellency and UV resistance
2024 - IRG/WP 24-20716
Cross-laminated timber (CLT) has emerged as a revolutionary building material, offering a sustainable alternative to traditional construction methods. By layering and bonding multiple layers of wood at right angles, CLT creates a robust and versatile structural element capable of supporting significant loads while promoting eco-friendliness and design flexibility. However, despite its numerous adv...

Assessment of historical pilings from Lisbon
2024 - IRG/WP 24-41004
The renovation and rebuilding of areas in Lisbon has led to work on buildings constructed in the Pombaline downtown district. These buildings were constructed on wooden pilings, as a means of stabilising unstable soils and transfer the loads from buildings to soils with adequate bearing capacity. These methods also increased the resilience of the reconstruction works to future possible earthquakes...

Evaluating the potential for re-using timber from deconstructed sea defence groynes from the Bournemouth groyne field
2024 - IRG/WP 24-50397
In the shadow of a looming climate crisis, the modern age construction industry is evolving. The for implementing sustainable practices has never been greater and the potential role of the circular economy is front and centre. It can play a pivotal role in transforming the industry by promoting sustainable practices which emphasise the need to reduce consumption of natural resources. Re-using timb...

Timber circularity discussion: Waste hierarchy and prioritising reuse opportunities!
2024 - IRG/WP 24-50398
By following the waste hierarchy and prioritising reuse opportunities first before resorting to disposal in landfills, we can effectively sustainably manage timber resources. This approach helps to conserve natural resources, reduce energy consumption, minimize greenhouse gas emissions, and minimize the overall environmental footprint associated with timber production and disposal. It also promote...
