Abstract
WoodST is capable of calculating heat transfer, charring rate, load-displacement curve as well as the time and mode of failure of timber structures exposed to fire, thus providing a cost-competitive solution for the fire safety analysis of timber structures. This InfoNote briefly introduces the development and verification of WoodST. Two applications of WoodST are also demonstrated.

Abstract
WoodST est capable de calculer le transfert de chaleur, la vitesse de carbonisation, la courbe charge-déplacement ainsi que le moment et le mode de défaillance des structures en bois exposées au feu, offrant ainsi une solution à coût compétitif pour l'analyse de la sécurité incendie des ossatures en bois. La présente note d’information présente brièvement le développement et la vérification de WoodST. Deux applications de WoodST sont également présentées.

Abstract
The objective of this research is to address a knowledge gap related to fire performance of midply shear walls. Testing has already been done to establish the structural performance of these assemblies. To ensure their safe implementation and their broad acceptance, this project will establish fire resistance ratings for midply shear walls. Fire tests will provide information for the development of design considerations for midply shear walls and confirm that they can achieve at least 1-hour fire-resistance ratings that are required for use in mid-rise buildings.
This research will support greater adoption of mid-rise residential and non-residential wood-frame construction and improve competition with similar buildings of noncombustible construction. This work will also support the development of the APA system report for midply walls, which will be a design guideline for using midply walls in North America.

Abstract
The USDA Forest Service’s Qualified Product List (QPL) provides guidance on the range of permissible mix ratios for water-enhancer products. Due to the proprietary nature of water-enhancer products, there are several unknowns about the rheology of the permissible mix ratios. This study focused on mapping the viscosity of various suppressant products as a function of their mix ratios. The results revealed a wide range of viscosities across products, with each product showing a different non-linear relationship with different mix ratios. The results from this study can help understand the optimum viscosity range to achieve desired drop characteristics during aerial operations.

Abstract
The aim of this study was to capture data on area-based water delivery systems, specifically in the context of logistics, systems differentiation, water delivery, and its localized effects. FPInnovations successfully collaborated with Fire & Flood to obtain this data. A two-day test was executed during which Fire & Flood set up their 4- and 12-inch systems and carried out sprinkler operations.

La construction massive en bois est relativement nouvelle et sera bientôt intégrée dans le Code national du bâtiment du Canada (CNB). Il s'agit d'une solution à base de bois à prix compétitif qui complète les systèmes existants à ossature en bois et de construction en gros bois d’œuvre et constitue une option appropriée pour certaines applications qui utilisent actuellement du béton, de la maçonnerie ou de l'acier.

Abstract
Alberta Agriculture and Forestry’s (AAF) Wildfire Management Branch recently contracted two Sikorsky S-61N heavy helicopters. Both helicopters are equipped with an external tank (max. volume 1000 U.S. gallons) and have on-board injection systems that are capable of mixing class A foams and water-enhancers. Currently, there is limited data on comparative drop footprints of foam and water-enhancers (suppressants) for these heavy helicopters. To fill this knowledge gap, AAF has asked FPInnovations to conduct drop tests in different wildland fuel environments. This study focuses on mapping the drop footprints of water, foam, and water-enhancers in black spruce stands at specific flight parameters.

Abstract
Mass timber construction is a relatively new type of construction soon to be implemented in the National Building Code of Canada (NBCC). It is a cost-competitive wood-based solution that complements existing wood-frame and heavy timber systems and is a suitable candidate for some applications which currently use concrete, masonry and/or steel.
