Abstract
Les panneaux en bois lamellé-croisé (CLT) peuvent offrir une excellente résistance au feu, souvent comparable à celle des constructions lourdes typiques non combustibles. En raison de la nature inhérente des pièces en gros bois d’oeuvre à carboniser lentement et à un taux prévisible, les systèmes en bois massif peuvent maintenir une capacité structurale significative pour des durées prolongées lorsque exposés au feu. Afin de faciliter l’acceptation de futures dispositions du code pour la conception des panneaux de CLT résistant au feu, un projet de recherche d’un an a été lancé chez FPInnovations en avril 2010. L’objectif principal du projet était de développer et de valider une procédure générique pour calculer les caractéristiques de résistance au feu des assemblages de mur et de plancher de CLT. Une série d’essais de comportement au feu en vrai grandeur est en cours pour comparer le degré de résistance au feu mesuré lors de tests standards à celui calculé en utilisant la procédure proposée. Compte tenu du fait que le projet de recherche en est à ses débuts (lors de la rédaction de ce chapitre), une procédure de conception simple, mais conservatrice, est présentée dans ce chapitre, selon l’information de pointe provenant de l’Europe et de l’Amérique du Nord. La norme canadienne sur les règles de calcul des charpentes en bois (CSA O86) peut être employée pour calculer le degré de résistance au feu des panneaux de CLT avec la même méthodologie qui est actuellement employée pour calculer les degrés de résistance au feu du bois de construction lamellé-collé et du gros bois d’oeuvre aux États-Unis, en Nouvelle-Zélande et en Europe. Cette méthode est connue sous le nom de « méthode de la section résiduelle ou efficace » et permet l’utilisation des valeurs de calcul que l’on retrouve dans la norme CSA O86. On recommande de faire appel à un ingénieur qualifié en protection contre les incendies pour diriger ou surveiller la conception des assemblages de CLT afin d’obtenir le degré de résistance au feu désiré. L’ingénieur en protection contre les incendies devrait travailler étroitement avec l’ingénieur en structure afin de bien évaluer les effets de l’exposition au feu sur la structure.

Abstract
The fire resistance of cross-laminated timber (CLT) could be improved by treating the lamina with fire retardants. The major issues with this technology are the reduced bondability of the treated lamina with commercial adhesives. This study assessed several surface preparation methods that could improve the bondability and bond durability of fire-retardant treated wood  with  two  commercial  adhesives.  Four  surface  preparation  methods,  including  moisture/heat/pressure, surface planing, surface chemical treatment, and surface plasma treatment were assessed for their impact on the bondability and bond durability of lodgepole pine lamina. The block shear test results indicated that all surface preparation methods were somewhat  effective  in  improving  bond  performance  of  fire-retardant  treated  wood  compared to the untreated control wood samples, depending on the types of fire retardants and wood adhesives applied in the treatment process and bonding process. The selection of surface preparation, fire retardant, and wood adhesive should be considered interactively to obtain the best bond properties and fire performance. It may be possible to effectively bond the treated lamina with PUR adhesive without any additional surface preparation for the fire retardant used in the treatment at FPInnovations.

Abstract
Mulching is a common method of fuel treatment. However, it is not currently listed by the U.S. Forest Service as a fuel type in its recommendations for fire retardant coverage levels. FPInnovations researchers set up plots with different coverage levels of retardant on a mulch fuel bed and collected fire behaviour data when a fire interacted with these plots. The results are intended to help wildfire agencies understand the effectiveness of retardant on mulch fuels in developing better suppression plans.

Abstract
Currently, mass timber building designs commonly incorporate a concrete floor topping. This can improve building accoustics by increasing the mass of the assembly, reduce floor vibration and create a smooth flat surface to install finish flooring on. The installation of concrete requires formwork, pouring and finishing the concrete and time to cure which adds to project schedules. One way to address this is to use mass timber elements that are prefabricated with concrete toppings preinstalled. Replaceing the concrete floor toppings wiht dry alternatives, such as cement board, may also reduce construction timelines, while still ensuring adequate acoustic and vibration performance. Cement board needs only to be screwed in place and can be walked on immediately after installation; this reduction in construction time may reduce overall project costs and help make wood buildings more cost competitive than other types of construction.

Abstract
The City of Quesnel, B.C. has applied an innovative selective harvesting technique in a mature Douglas-fir forest stand with the objectives of maintaining biodiversity and reducing fuel-load buildup and consequent wildfire threat. FPInnovations researchers monitored and documented the harvesting operations and measured machine productivity to evaluate the cost-effectiveness of the operation. To support the assessment of fuel-load reduction, FPInnovations’ Wildfire Operations group conducted pre- and post-harvest fuel-sampling activities to evaluate changes in forest fuel components.

Abstract
These concealed or void space cases require installation of elements which represent additional material cost and labour. For wood buildings that rely heavily on prefabrication, these steps can have a significant impact on scheduling. Removing dependence on concrete and gypsum board in certain applications could make wood buildings more cost competitive to similar buildings of steel and concrete and could further enhance the benefits of prefabricated construction.
