This webinar will present the fire safety challenges of tall wood buildings, specifically discuss the contribution of Cross Laminated Timber (CLT) building elements. Under the auspices of the Fire Protection Research Foundation, the second phase research on fire safety challenges of tall wood buildings was conducted to quantify the contribution of cross-laminated timber (CLT) building elements in compartment fires. The research encompassed literature review, experiments and modeling. Based on gap identification in the literature review, a series of full-scale CLT compartment fire tests were designed and conducted under various exposure conditions and produced a large amount of experimental data including heat release rates, heat fluxes, char patterns and char depths. The experimental data were analyzed and used to quantify the contribution of CLT building elements to compartment fires. Additionally, an intermediate scale fire testing method was developed to identify adhesives that lead to an improved fire performance and a reduced contribution of CLT to the fire. An engineering calculation method, validated using the experimental results, was refined to predict the influence of exposed CLT on the severity and the duration of compartment fires. The technical data developed from this project will enable designers to develop a fire protection strategy to mitigate the potential hazard to occupants, fire fighters and property. Full final reports on this research are available from the Foundation's website.

If you would like to hear more from Joseph Su and Daniel Brandon on this topic, as well as other thought leaders, please plan to attend the NFPA Conference & Expo® - June 11 - 14, Las Vegas - one of the world’s largest and most comprehensive fire, electrical, and life safety education events. For details visit www.nfpa.org/conference. Dr. Joseph Su is a Principal Research Officer, Group Leader at the National Research Council Canada’s Fire Safety Unit. He has over 30 years research experience in combustion chemistry, fire development, fire detection and suppression, fire performance of materials and systems and full-scale fire testing with over 200 publications. Currently, he serves as the International Convener of ISO/TC92/SC3/Working Group 2 (Generation and Analysis of Fire Effluents). He was a recipient of the 2000 Jack Bono Engineering Communications Award from the Society of Fire Protection Engineers. Dr. Daniel Brandon works as a researcher at Research Institutes of Sweden - Fire Research. He has a PhD degree from the University of Bath in the UK, where he studied the behavior of timber connections in fire and ambient conditions. He is currently leading national and international research projects on fire safety in timber buildings. Furthermore, he is a Swedish delegate in the Eurocode CEN SC5 committee, dealing with the revision of the European standardization for Structural Fire Design of timber structures. Recently, he received the Howard medal for best paper from the Institution of Civil Engineers.
