Experimental study on compressive strength performance of cross laminated timber with biodeterioration damage
2019 - IRG/WP 19-40883
The mass timber construction has attracted attention around the world. The reasons are due to the environmental impacts and the potential of the strength performance and quantity of the wood. Nowadays, CLT is one of the most important materials for the timber constructions. If we use CLT as a building material, we should consider the biodegradation risk for long time use. From an estimation of fut...

Estimation of residual compressive strength on cross laminated timber with biodeterioration damage
2021 - IRG/WP 21-40918
CLT is susceptible to biodeterioration such as fungal decay and termite attack during long-term use for buildings. It is necessary to know the residual strength performance of biodegraded CLT for estimating future performance and aging of CLT. In this study, compression tests of CLT damaged by brown rot fungi and termites were conducted to clarify the relationship between residual strength and mas...

Process Development in Continuous Wood Densification and the Influence of Ionic Liquids on Set-Recovery and Mechanical Properties
2025 - IRG/WP 25-30827
The densification of wood significantly enhances its mechanical properties, making low-density species more viable for high-performance applications. However, challenges such as set-recovery (SR) and production speed hinder large-scale adoption. This study investigates continuous surface densification using a custom-built belt press and examines the effect of chemical pre-treatment with ionic liqu...

Considerations on how different preservation processing methods of logs would have different effects on wood structures
2025 - IRG/WP 25-41040
Azekura-zukuri style wood structures (hereinafter referred to as azekura-style structures) have been utilized in forest conservation projects in Japan as substitutes for concrete structures. We estimate that making use of thinned and small logs for azekura-style structures has positive impact on circular economy and carbon fixation and contributes to the biodiversity within their areas. In additio...
