A Comparison of Cross-Laminated Timber (CLT) Floor Panels using Finite Element Analysis and Experimental Fire Testing
2022 - IRG/WP 22-40955
Cross-laminated timber (CLT) is a relatively new timber product and has gained popularity in North America and Europe as a construction material. As a sustainable engineered timber product, CLT offers many advantages over solid wood, concrete, or steel construction. However, the use of timber in medium to high rise buildings is often avoided mainly due to its combustible nature. In this paper, a n...

Field durability testing of wood above ground - Part 1: 15 years’ experience with the Bundle method
2023 - IRG/WP 23-20695
A ‘jack of all trades’ method for above-ground wood durability testing has been sought for decades, but until now no method has found its way into standardization. The method of choice shall be applicable for untreated and treated wood – ideally also for wood composites. It shall be reproducible, objective, fast, easy, and inexpensive. Finally, it shall provide high predictive power.
This s...

Field durability testing of wood above ground - Part 2: The full guideline of the Bundle method
2023 - IRG/WP 23-20696
To determine the biological durability of wood above ground, numerous approaches for test methods have been pursued and tried out in the field in the past. So far, no method has managed to find its way into a European standard. During the last 15 years, experience with the Bundle method has been gained. As described in Part 1 of this paper, the method is recommended as a suitable tool for determin...

Characterisation of fungal decay in cable car trestles in Svalbard
2023 - IRG/WP 23-11031
The Arctic will be strongly affected by climate change. In Svalbard the coal mining industry were established in the early 20th century. All man-made structures and sites dating before 1946 in Svalbard are protected by law and considered as cultural heritage. This included the massive cable car trestles that are constructed from untreated Norway spruce and mounted directly into the soil. We hereby...
