Relationships between deterioration part and structural performance in wooden houses
2023 - IRG/WP 23-50376
Based on the survey examples, there are four patterns of deterioration that tend to occur in plywood bearing walls of wooden houses in Japan. The first is a pattern in which wall is in a whole deterioration. It is a no damage wall or test specimen. The second is a pattern in which only the sill is deteriorating. It is caused by moisture or termites from ground to the base. In addition, there is a ...

Nasutitermes exitiosus and wood-rotting fungi in Eucalyptus regnans, E. acmenioides, E. wandoo, and E. marginata: force-feeding, laboratory study
1985 - IRG/WP 1231
Under a force-feeding regime, the termitid Nasutitermes exitiosus was fed on four eucalypt timbers infested with several fungal species to investigate the influence of such fungus-infested timbers on mass of wood lost, termite biomass, fat content and water content. The results showed that wood mass losses were markedly affected by species of fungi and timber. The interaction of fungi and timbers ...

Monitoring a Timber Bridge in Norway
2004 - IRG/WP 04-40282
We have instrumented three different timber bridges in Norway for the Norwegian Public Roads Administration. The goal was to learn more about the properties of timber bridges. We have instrumented Evenstad Bridge, Daleråsen Bridge and the last year Flisa Bridge. All bridges are have creosoted glulam trusses and creosoted stress laminated deck. Evenstad and Flisa have an asphalt deck on top, while...

Wet and dry adhesion of coatings on modified and unmodified wood: comparison of the pull-off test and the cross-cut test
2010 - IRG/WP 10-40524
The objective of this paper is to study the influence of several types of modification (acetylation, furfurylation, thermal modification) on coatings adhesion and to compare two methods of assessing the adhesion: the cross-cut test and the pull-off test both tested in dry and wet conditions. The study also investigates the effect of other parameters of the wood substrates on adhesion like the ring...

Wet and dry adhesion of coatings on modified and unmodified wood: influence of 18 months of natural weathering on the pull-off test and cross-cut test results
2011 - IRG/WP 11-40569
The objective of this paper is to study the influence of several types of modification (acetylation, furfurylation, heat treatment) on coatings adhesion after 18 months of natural weathering according to EN 927-3 in Vienna (Austria).
The paper compares two methods for assessing the adhesion: the cross-cut test (EN ISO 2409) which is the conventional method used and recommended in EN 927-3 and th...
