Abstract
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
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.

Abstract
FPInnovations recently tested a data collection system developed by Voice Directed Tally Systems (VDTS). Following an initial virtual demo of the product, FPInnovations agreed that the system might be interesting to FPInnovations’ member companies. This InfoNote presents a summary of in-field testing conducted in March 2021.

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
Mid-rise and tall-wood buildings are gaining in popularity in the marketplace. Compared to the traditional low-rise buildings, wind-induced vibrations need to be controlled in taller buildings. Due to the lightweight nature of wood construction, wind-induced vibrations are larger in amplitude when compared to buildings built with heavier materials, such as concrete. The NBCC design method requires natural frequencies and damping ratios as inputs (NRC 2015). However, there is little data available about mid-rise and tall-wood buildings' dynamic performance (i.e., frequencies and damping ratios). Lack of data and experience of the wind-induced vibration performance of wood buildings can result in unsatisfactory design of mid-rise wood buildings, which can undergo excessive wind-induced vibration. It can also result in unnecessary overdesign of mid-rise and tall-wood buildings with increased construction costs.

Abstract
Twelve SBB (spruce bark beetle killed) grade 2 logs were received by FPInnovations, three were confidently assigned a grade 2, but nine were considered suspicious, as the scalers suspected that some internal defects could not be correctly identified visually. CT (computer tomography) scanning and analysis revealed that decay and checking were more extensive than externally visible defects indicated, which led to downgrading 2 logs to grade 4. Pressure treating one of the apparently good quality logs with water and re-scanning enhanced the visibility of the number and depth of checks in CT images and led to downgrading that log as well. Two of the suspicious logs were warmed for 24 hours at 22 degrees to simulate exposure to one summer day in BC Interior, but unlike typical dry pine logs, the many fine checks around these logs opened evenly, without revealing the true depth of any. Another two suspicious logs with signs of decay were cut to analyse decay extent. The decay was far more extensive than even visible in CT images, leading to downgrade of both logs. Overall, 4 of the nine logs considered suspicious and one of the 3 considered good quality SBB killed grade 2 logs were downgraded due to checks and decay not visible to scalers on the study. Although these results are neither statistically significant nor comprehensive, they point to the challenge of scaling SBB logs correctly, without knowledge of internal defects.

Abstract
FPInnovations’ Wildfire Operations Advisory group has asked its researchers to explore a method by which the performance of water-enhancing products can be repeatedly assessed in the laboratory. A new test method, known as the crib test, was designed to evaluate the effectiveness of water-enhancing products on burning woody fuel to simulate direct-attack aerial operations. This report outlines the methodology for the crib test and describes the findings from performance evaluation tests conducted at the Protective Clothing and Equipment Research Facility (PCERF) at the University of Alberta.

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.
