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
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
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
This review explores the benefits, challenges, limitations, logistics, and cost-effectiveness of different management options to convert conifer-dominated stands to aspen-dominated stands. These alternatives can include overstory removal (harvesting, bulldozing, shear blading, prescribed burning) and site preparation (root trenching, drag scarification, broadcast burning) treatments. On sites where parent aspen trees are not present in the original stand, tree planting will be necessary albeit costly in comparison to regeneration by suckering. While extensive literature exists on the regeneration of trembling aspen through suckering, research on artificial establishment with seedlings and its requirements is still in its infancy and rapidly developing.

Abstract
Hosted by Edouard Proust, this webinar presentation by David Bevly held on February 10, 2021 highlights an important component of FPInnovations' Transportation and Infrastructure group's work. The concept of truck platooning, inspired by pelotons of cyclists and originally developed for highway use to obtain fuel savings, utilizes technology to maintain the desired distance between trucks by controlling acceleration and braking, and the relative lateral position of the vehicles by steering, reacting faster than a driver can. Truck platooning has attracted the attention of the natural resources sector and its implementation is expected to increase the productivity of drivers. By allowing the operation of driverless following trucks replicating the path set by the human operated leader vehicle, the concept could help mitigate the workforce shortage that impact the sector while supporting the supply of lumber to mills across the country.
Abstract
Ce contenu est exclusivement en anglais. Merci de contacter notre équipe si vous souhaitez obtenir de l’information en français. Cette présentation de David Bevly a été organisée le 10 février 2021 par Edouard Proust. Elle met en lumière une composante importante du travail effectué par le groupe Transports et Infrastructures de FPInnovations. Le concept d’opération de camions en peloton est inspiré des pelotons de cyclistes et a été mis au point à l’origine pour des applications autoroutières avec pour objectif une réduction de la consommation de carburant. Les camions sont équipés d’une technologie permettant le contrôle de l’accélération, du freinage et de la direction offrant la possibilité de maintenir la distance de suivi entre les véhicules ainsi que leur positionnement latéral relatif. En autorisant la mise en œuvre de camions suiveurs entièrement autonomes et qui répliquent le tracé du camion de tête opéré par un chauffeur, le concept pourrait à terme aider à minimiser l’impact du manque de chauffeurs dans l’industrie tout en supportant l’approvisionnement en fibre des scieries à travers le Canada.

Abstract
The clean air initiative led by the British Columbia Ministry of Environment seeks to develop innovative methods to improve community air quality by utilizing harvest residues and minimizing the volume of fibre burned at roadside. Retaining processed tops as roadside oriented piles is proposed as an alternative to burning debris. These burn trials have demonstrated that in this unique arrangement of fuels and interaction of site-specific variables, particular areas of the piles will be more vulnerable to ignition sources which can lead to sustained burning and high intensity fire behaviour. In addition to the low fuel moisture conditions, other fuel properties, such as the close proximity of piles, high volume of fine fuels (branches and needles) and orientation of piles to road all contributed to enhanced burning at this site.

Abstract
Building high energy efficiency has become a must to reduce carbon emission from the built environment and to meet needs of consumers. Industrialized construction provides an effective way to produce highly insulated and airtight building envelopes to achieve superior building performance, such as Net Zero Energy. However, it is important that as other attributes (e.g., seismic, wind, fire, vibration, etc.) are being addressed, further research is needed to develop well rounded building envelope solutions. Meanwhile, improvement may be made in automated production equipment and software to optimize and monetize these solutions.

Abstract
Il est devenu indispensable de construire des bâtiments à haute efficacité énergétique pour réduire les émissions de carbone dans l’environnement et répondre aux besoins des consommateurs. La construction industrialisée est un bon moyen de produire des enveloppes de bâtiment bien isolées et étanches à l’air et, par le fait même, d’accroître la performance énergétique des bâtiments (p. ex consommation énergétique nette zéro). Cependant, il est important de tenir compte d’autres attributs (p. ex. charges sismiques, vent, feu, vibrations, etc.). Il faudra poursuivre les recherches pour trouver des solutions durables en matière d’enveloppes de bâtiment. Entre-temps, il est possible d’améliorer l’équipement de production automatisée et le logiciel qui l’accompagne afin d’optimiser et de rentabiliser ces solutions.

Abstract
This new study aims to generate hygrothermal, particularly moisture-related performance data for light wood-frame walls meeting the R22 effective (RSI 3.85) requirement for buildings up to six storeys in the City of Vancouver. The overarching goal is to identify and develop durable exterior wood-frame walls to assist in the design and construction of energy efficient buildings across the country. Twelve test wall panels in six types of wall assemblies are assessed in this study. The wall panels, each measuring 4 ft. (1200 mm) wide and 8 ft. (2400 mm) tall, form portions of the exterior walls of a test hut located in the rear yard of FPInnovations’ Vancouver laboratory. This report, second in a series on this study, documents the performance of these wall assemblies based on the data collected over 19 months’ period from October 2018 to May 2020, covering two winter seasons and one summer.
