Abstract
Midply shear wall (hereafter Midply), which was originally developed by researchers at Forintek Canada Corp. (predecessor of FPInnovations) and the University of British Columbia, is a high-capacity shear wall system that is suitable for high wind and seismic loadings. Its superior seismic performance was demonstrated in a full-scale earthquake simulation test of a 6-storey wood-frame building in Japan. In collaboration with APA–The Engineered Wood Association and the American Wood Council (AWC), a new framing arrangement was designed in this study to increase the vertical load resistance of Midply and make it easier to accommodate electrical and plumbing services. In this study, a total of 14 Midply specimens in six wall configurations with different sheathing thicknesses and nail spacing were tested under reversed cyclic loading. Test results showed that Midply has approximately twice the lateral load capacity of a comparable standard shear wall. The drift capacity and energy dissipation capability are also greater than comparable standard shear walls. For Midply to use the same seismic force modification factors as standard shear walls, seismic equivalency to standard shear walls in accordance with ASTM D7989 was also conducted. Although Midply has superior lateral load and drift capacities, it does not seem to be as ductile as the standard shear walls at the same over-strength level. Additional testing and dynamic analysis are recommended to address this issue.

Abstract
In this project, the main objective was to evaluate the “best bet” experimental mat structure design previously identified by FPInnovations in 2018/19. This mat structure was comprised of three strand size classes incorporated into six equal weight mat layers. Both experimental and control panels were prepared at 39lb/ft³ and 35lb/ft³ densities and tested for dry static bending, single cycle bending (D4), concentrated static load, thickness swell, and internal bond strength.

Abstract
This report reviews life cycle assessment (LCA) based regulatory approaches that have been adopted in several countries to evaluate and improve environmental impacts of cosntruction products and buildings. Recommendations are provided for incorporating LCA into Canadian regulations (including the National Building Code of Canada), and for enhancing building LCA guidelines to address principles of consistency, simplicity, and representative data which can improve the effectiveness of LCA to achieve regulatory objectives. This work supports the project need of guidance for performance-based design to accelerate the introduction of wood-based systems. The findings of this review can be used to help accelerate the adoption of life cycle-based regulations for buildings and infrastructure in Canada.

Abstract
In the construction of buildings, the timber-concrete (TCC) system can be a cost-competitive solution for floors with longer spans, since the mechanical properties of the two materials are used efficiently. Furthermore, the additional mass from the concrete improves the acoustic performance compared to a timber floor system alone. Nevertheless, TCC floors are not commonly used in buildings in Canada, due to the absence of technical guidelines for such types of structural systems in this country.

Abstract
Braced timber frames (BTFs) are one of the most efficient structural systems to resist lateral loads induced by earthquakes or high winds. Although BTFs are implemented as a system in the National Building Code of Canada (NBCC), no design guidelines currently exist in CSA O86. That not only leaves these efficient systems out of reach of designers, but also puts them in danger of being eliminated from NBCC. The main objective of this project is to generate the technical information needed for development of design guidelines for BTFs as a lateral load resisting system in CSA O86. The seismic performance of 30 BTFs with riveted connections was studied last year by conducting nonlinear dynamic analysis; and also 15 glulam brace specimens using bolted connections were tested under cyclic loading.
In the second year of the project, a relationship between the connection and system ductility of BTFs was derived based on engineering principles. The proposed relationship was verified against the nonlinear pushover analysis results of single- and multi-storey BTFs with various building heights. The influence of the connection ductility, the stiffness ratio, and the number of tiers and storeys on the system ductility of BTFs was investigated using the verified relationship. The minimum connection ductility for different categories (moderately ductile and limited ductility) of BTFs was estimated.

Abstract
Decking markets in Canada lack options of hybrid designs and are generally limited to smooth 5/4” or 2x6” of either pressure treated wood, cedar, tropical hardwoods or wood plastic composites. Profiled decking has been unsuccessful in entering the Canadian market on a large scale even though globally it is more prevalent. This report looks to leverage FPInnovations’ expertise to identify opportunities to improve the stability, durability, performance and competitiveness of wood decking by combining profiling and treatment with additional non-wood materials. This information will be used to develop prototypes of novel wood-based decking products that would suit the needs of Canadian consumers as well as maintaining or expanding the solid wood decking market for Canadian producers. Six hybrid decking models were conceptualized to address market concerns about wood decking.

Abstract
These concealed or void space cases require installation of elements which represent additional material cost and labour. For wood buildings that rely heavily on prefabrication, these steps can have a significant impact on scheduling. Removing dependence on concrete and gypsum board in certain applications could make wood buildings more cost competitive to similar buildings of steel and concrete and could further enhance the benefits of prefabricated construction.

Abstract
Currently, mass timber building designs commonly incorporate a concrete floor topping. This can improve building accoustics by increasing the mass of the assembly, reduce floor vibration and create a smooth flat surface to install finish flooring on. The installation of concrete requires formwork, pouring and finishing the concrete and time to cure which adds to project schedules. One way to address this is to use mass timber elements that are prefabricated with concrete toppings preinstalled. Replaceing the concrete floor toppings wiht dry alternatives, such as cement board, may also reduce construction timelines, while still ensuring adequate acoustic and vibration performance. Cement board needs only to be screwed in place and can be walked on immediately after installation; this reduction in construction time may reduce overall project costs and help make wood buildings more cost competitive than other types of construction.

Abstract
Cross-Laminated Timber (CLT) is an engineered mass timber product manufactured by laminating dimension lumber in layers with alternating orientation using structural adhesives. It is intended for use under dry service conditions and is commonly used to build floors, roofs, and walls. Because prolonged wetting of wood may cause staining, mould, excessive dimensional change (sometimes enough to fail connectors), and even result in decay and loss of strength, construction moisture is an important consideration when building with CLT. This document aims to provide technical information to help architects, engineers, and builders assess the potential for wetting of CLT during building construction and identify appropriate actions to mitigate the risk.

Abstract
Le bois lamellé-croisé (CLT) est un produit massif de bois d’ingénierie qui est fabriqué à partir de multiples pièces de bois de dimension assemblées en couches orthogonales avec des adhésifs structuraux. Ce produit est conçu pour des conditions de service sèches et est couramment utilisé pour construire des planchers, des toits et des murs. Comme l’humidification prolongée du bois peut causer des taches, de la moisissure, des variations dimensionnelles excessives (parfois suffisantes pour provoquer la défaillance des attaches), et même la pourriture et la perte de résistance, l’humidité est un facteur important dans la construction avec le CLT. Le présent document a pour but de fournir de l’information technique pouvant aider les architectes, les ingénieurs et les constructeurs à évaluer les risques d’humidification du CLT pendant la construction de bâtiments et à prendre les mesures appropriées pour atténuer ces risques.
