Effect of incised pattern on flexural strength of CLT
2023 - IRG/WP 23-40993
As a study aimed at developing preservation methods suitable for CLT, investigations have been carried out using “deep penetration treatment”. This treatment method was originally developed as a treatment method for sawn lumber and glulam used as sill members. In the treatment, materials are incised using specially designed blades and immediately sprayed with an oil-based wood preservative. Th...

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 ...

Manufacturing of bamboo hybrids with high strength, superior fire retardancy, and dimensional stability
2024 - IRG/WP 24-30808
Bamboo, renowned for its rapid growth, high strength-to-weight ratio, and eco-friendly attributes, has found extensive use in decorative building materials and glue-laminated beams. However, the inherent challenges of dimensional instability and flammability in natural bamboo restrict its broad application. This research introduces a range of environmentally friendly techniques aimed at producing ...
