This webinar presents key results from the PhD of Andreas Sæter Bøe, where two large-scale cross-laminated timber experiments were conducted. The compartment was 95 m2. In the first experiment, named #FRIC-01, the ceiling was exposed, while in the second experiment, #FRIC-02, both the wall and the ceiling were exposed. These experiments aimed to better understand how two different configurations of CLT affect the fire dynamics, including fire spread inside the compartment, external flames, charring rate of CLT, decay phase, self-extinguishment of flames and delamination.
In both experiments, the ignition of the CLT ceiling triggered a clear change in the fire dynamics, in which flames spread under the ceiling and caused a strong radiative heat flux to the wall and the wood crib. The increased radiative heat flux effectively preheated the wood crib (and the wall in #FRIC-02) and led to a significantly faster spread across the wood crib than before the CLT was ignited.
The information above is originally written in the PhD-thesis of Andreas: “Experimental investigations on fire performance of the engineered wood products products cross-laminated timber and I-joists.”
When: December 14, 2023 11:00 - 12:00 AM (Oslo time)
Speaker: Andreas Sæter Bøe, PhD candidate at Norwegian University of Science and Technology (NTNU) and Research scientist at RISE Fire Research
The webinar is free, open to all, and will be held in English.
The webinar will be recorded and published at fric.no.
The research has been carried out as a part of work package 3 in FRIC.
