Performance of 3-iodo-2-propynyl butyl carbamate (IPBC) in L-joints under tropical conditions
2016 - IRG/WP 16-30688
The ability of 3-iodo-2-propynyl butyl carbamate (IPBC) to protect wood against fungal decay out of soil contact was evaluated using ponderosa pine L-joints at two exposure sites over a 12 year period. IPBC tended to provide better protection when formulated in an organic solvent and when applied using a double vacuum treatment. Performance also tended to be better when systems contained a water...

Influence of sea water on timber and metal joints
2017 - IRG/WP 17-40818
In the Great East Japan Earthquake that occurred in March 2011, many buildings suffered from seawater immersion caused by the tsunami. Saito's study revealed that corrosion progresses on metal plate that experienced seawater immersion 1). However, the detailed mechanism of corrosion progresses has not yet been clarified. Therefore, in this study, salinity which is one of causes of corrosion w...

Joints design considerations in indoor high humidity conditions
2022 - IRG/WP 22-40950
In recent years, a number of cases of degradation by wood destroying fungi have been detected in covered timber structures such as pools, wineries, bathrooms, etc. – in fact, any building where indoor air may reach high humidity values during certain periods of time.
The origin of this kind of decay was not related to water leaks, but to the condensation of the water vapor over the steel connec...

Estimation of single shear strength performance of screw joints with decayed wood
2023 - IRG/WP 23-40968
In order to use existing wooden structures for a long term, it is necessary to evaluate appropriately the damage degree of bio-deterioration of the structural performance including the members and joint systems. As one for them, it is necessary to estimate more accurate the single shear strength performance of screw joints with decay. Therefore, we proposed the model considering the yield strength...
