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
Au Québec, l’intervention de récolte forestière la plus répandue en forêt résineuse est la coupe avec protection de la régénération et des sols (CPRS). Cette intervention consiste à récolter toutes les tiges marchandes (10 cm et plus au DHP) tout en protégeant la régénération préétablie et les sols. Pour ce faire, la machinerie forestière se restreint à emprunter des sentiers espacés de manière à limiter les superficies perturbées. Dans les peuplements à structure irrégulière ou étagée, la CPRS n’est pas toujours le traitement le plus approprié. Ces peuplements sont composés d’une portion variable de tiges ayant un diamètre à hauteur de poitrine (DHP) de 10 à 12 cm qui pourrait contribuer de manière significative au volume d’un peuplement futur. Ces petites tiges sont dispendieuses à récolter, elles diminuent le rendement en bois de sciage et elles ont peu d’influence sur le volume total récolté. Pour aménager adéquatement les peuplements à structure irrégulière ou étagée, la coupe avec protection des petites tiges marchandes (CPPTM) a été développée. La CPPTM ressemble à la CPRS, à l’exception que les tiges de 10 et 12 cm (parfois jusqu’à 16 cm) sont protégées. Ce traitement est actuellement pratiqué dans plusieurs régions et sera ajouté à la 4e édition du Manuel d’aménagement forestier. Le présent document traite de l’approche opérationnelle de la CPPTM avec la machinerie forestière utilisée au Québec.

Abstract
FERIC monitored a trial of the Trans-Gesco TG88C and Tigercat 635 grapple skidders operations working in central Alberta. Harvesting was done in the summer on cutblocks designed to minimize road construction. Skidding distances were up to 1500 m. The productivity and cost of the skidding operation are presented, and the two machines are compared.

Abstract
It can be observed from this review that most fire safety provisions are similar in nature, whether the Chinese, Canadian or American provisions are applied. However, the Chinese code seems to be slightly more restrictive than the North American building codes with respect to wood-use allowances.

Abstract
During harvesting operations, soft soils with a reduced bearing capacity are susceptible to the creation of ruts. These can have negative consequences by altering the natural drainage and compacting the compacting the soil, which can lead to a loss of site productivity. site productivity. In a context of heavy rainfall or winter thaw, this vulnerability is accentuated and vulnerability is increased and mitigation measures are required. With collaborators in Abitibi, FPInnovations has studied various alternative alternative practices and developed a cost calculation tool that allows the to choose the least expensive option to reduce the presence and severity of ruts. ruts and their severity.
Abstract
Lors des opérations de récolte, les sols mous, à capacité portante réduite, sont sensibles à la création d’ornières. Celles-ci peuvent avoir des conséquences négatives en modifiant le drainage naturel et en compactant le sol, ce qui peut entraîner une perte de productivité du site. Dans un contexte de pluie abondante ou de dégel hivernal, cette vulnérabilité s’accentue et des mesures d’atténuation sont nécessaires. Avec des collaborateurs en Abitibi, FPInnovations a étudié différentes pratiques alternatives et développé un outil de calcul des coûts qui permet de choisir l’option la moins onéreuse afin de diminuer la présence d’ornières et leur gravité.

Abstract
FPInnovations studied a series of four partial harvesting trials and one combined partial harvesting–clearcut trial over three years in the Prince George (B.C.) Forest District. The partial harvesting trials harvested pine trees killed by the mountain pine beetle while protecting the non-pine secondary structure. The purpose of protecting the secondary structure is to provide a viable stand that will enhance the mid-term timber supply in 15 to 50 years. This report provides the costs, productivity, and harvesting damage results of the partial harvesting and clearcutting treatments used in the fifth and final trial. The pre-harvest stand was stocked with non-pine trees before harvesting, but was not stocked following the partial harvesting treatment. Slightly more than one-third of the net block area was clearcut for roads, trails, and landings. The trial results suggest up to 23% of the harvested non-pine overstory could potentially have been protected.

Abstract
In this FPInnovations–Feric Division project, we studied a series of partial harvesting trials in which the objective was to harvest all the pine trees while protecting the secondary structure in stands infested by the mountain pine beetle. The purpose of this type of treatment is to salvage the present value of the beetle-killed pine while preserving the existing secondary structure to provide a viable stand by the mid-term timber supply period (15 to 50 years from now). In this report, we provide the results from four trials in the Prince George (B.C.) Forest District using four different ground-based partial harvesting methods: a motor-manual (chainsaw) cut-to-length (CTL) method, a mechanized CTL method, a motor-manual full-tree method, and a mechanized full-tree method. Variations in pre-harvest stand attributes, harvesting equipment, and methodology resulted in differences in the total trail area, harvesting costs, and amount of secondary structure remaining undamaged in the residual stands. The results indicate that with an appropriate harvesting method and sufficient secondary structure present in the pre-harvest stand, it should be possible to harvest the mature pine trees and provide stands that will produce acceptable volumes of timber in the mid-term time period.
