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 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.

Abstract
Reduced surface evaporation rates are marketed as a competitive advantage by water-enhancer manufacturers. In this report, a new test method is developed and applied to quantify the evaporation rates of various commercially available water-enhancer products in a controlled environment. These quantified evaporation rates were then compared to the evaporation rate of water which served as the benchmark.

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
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
The design of wood-frame structural systems to withstand exposure to fire depends on knowledge of the fire endurance (time-to-failure) of the wood members used in the system. In fires, wood looses part of its load-carrying capacity due to charring and part due to strength degradation. This thesis examines the reduction in compression strength experienced by dimension lumber when exposed to elevated temperatures. A program of experimental testing of nominal 2×4 Machine Stress Rated (MSR) lodgepole pine lumber concentrically loaded in compression and exposed to elevated temperature was undertaken by Forintek Canada Corp., Canada's wood products research institute. A computer program entitled HTExposure was written to simulate the experimental time-to-failure data gathered in Forintek's testing program. This computer program combines a modification of an existing heat-transfer model with various published compression-strength reduction models. This was done in order to determine which of those strength-reduction models could predict times-to-failure comparable to the observed values. As well, a new compression-strength reduction model was proposed. When predicted results were compared to the observed data, it was determined that the computer program predicted results closest to those observed when using the new compression-strength reduction model proposed in this study.

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.
