Summary
Le présent rapport décrit une partie des activités de recherche et développement (R&D) en lien avec la démonstration de la résistance au feu ainsi que les études sur la performance acoustique effectuées dans le cadre de la construction du bâtiment Origine. Ce bâtiment est la tour résidentielle en bois massif la plus haute au Québec. Sa réalisation a débuté en 2015 à la suite des analyses préliminaires de faisabilité technique-économique qui se sont étalées pendant toute l’année 2014. La construction et l’installation se sont finalisées vers la fin de 2017. En premier lieu, le rapport présente les démarches liées à la réalisation d’un exercice de démonstration d’incendie pour une cage d’escaliers/ascenseur avec une chambre d’habitation adjacente, l’analyse de résultats et les principales conclusions en lien avec la pertinence de l’utilisation du bois massif pour des édifices de grande hauteur. En ce qui concerne la performance acoustique, le rapport présente la méthodologie d’étude et d’analyse des résultats des tests acoustiques pour des assemblages de mur et de plancher utilisés dans le projet Origine. De plus, ce rapport facilite la compréhension des activités réalisées et permet de montrer objectivement la capacité des produits en bois massif à offrir un environnement sécuritaire et confortable aux occupants de bâtiments multi-étagés. Les principaux résultats indiquent que les cages d’escaliers/ascenseur faites en bois massif, conçues pour une résistance au feu équivalente à celle faites en béton, peuvent offrir une excellente performance et servent d’alternatives adéquates pour les bâtiments multi-étagés. En ce qui concerne le développement d’assemblages acoustiques pour les murs et les planchers en bois massif, il a été prouvé qu’une approche multicritère permet d’offrir des solutions performantes à des coûts raisonnables. Finalement, il est clair que ce projet constitue un jalon très important dans le chemin d’acceptation des bâtiments multi-étagés en bois massif au Québec et au Canada. Sa construction, faite presque entièrement en bois, a nécessité de nombreux efforts économiques, de R&D, de conception et d’installation. De plus, les activités réalisées pour l’acceptation de ce type de construction ont permis de mettre en place de nouvelles technologies et des techniques de conception qui faciliteront la réplication de ce type de projet partout en Amérique du Nord.

Summary
Ascent, a 25 story residential tower located in Milwaukee, WI (USA), will become the tallest timber building in the world upon completion. This paper discusses the project's structural system, permit process, groundbreaking project specific testing, and several of the challenges the team overcame, all of which open the door to future Mass Timber projects; particularly in the United States.

Summary
Understanding how roof and floor systems (commonly called diaphragms by engineers) that are built from Pacific Northwest-sourced cross-laminated timber (CLT) panels perform in earthquake prone areas is a critical area of research. These building components are key to transferring normal and extreme event forces into walls and down to the foundation. The tests performed in this project will provide data on commonly used approaches to connecting CLT panels within a floor or roof space and the performance of associated screw fasteners. Structural engineers will directly benefit through improved modeling tools. A broader benefit may be increased confidence in the construction of taller wood buildings in communities at greater risk for earthquakes.

Summary
In response to the global drive towards sustainable construction, CLT has emerged as a competitive alternative to other construction materials. CLT buildings taller than 10-storeys and CLT buildings in regions of moderate to high seismicity would be subject to higher lateral loads due to wind and earthquakes than CLT buildings which have already been completed. The lack of structural design codes and limited literature regarding the performance of CLT buildings under lateral loading are barriers to the adoption of CLT for buildings which could experience high lateral loading. Previous research into the behaviour of CLT buildings under lateral loading has involved testing of building components. These studies have generally been limited to testing wall systems and connections which replicate configurations at ground floor storeys in buildings no taller than three storeys. Consequently, to develop the understanding of the performance of multi-storey CLT buildings under lateral loading, the performance of wall systems and connections which replicate conditions of those in above ground floor storeys in buildings taller than three storeys were experimentally investigated. The testing of typical CLT connections involved testing eighteen configurations under cyclic loading in shear and tension. The results of this experimental investigation highlighted the need for capacity-based design of CLT connections to prevent brittle failure. It was found that both hold down and angle bracket connections have strength and stiffness in shear and tension and by considering the strength of the connections in both directions, more economical design of CLT buildings could be achieved. The testing of CLT wall systems involved testing three CLT wall systems with identical configurations under monotonic lateral load and constant vertical load, with vertical loads replicating gravity loads at storeys within a 10-storey CLT building. The results show that vertical load has a significant influence on wall system behaviour; varying the vertical load was found to vary the contribution of deformation mechanisms to global behaviour within the elastic region, reinforcing the need to consider connection design at each individual storey. As there are still no structural design codes for CLT buildings, the accuracy of analytical methods presented within the literature for predicting the behaviour of CLT connections and wall systems under lateral loading was assessed. It was found that the analytical methods for both connections and wall systems are highly inaccurate and do not reflect experimentally observed behaviour.

Summary
The report describes a new structural system in wood that is the first significant challenger to concrete and steel structures since their inception in tall building design more than a century ago. The introduction of these ideas is fundamentally driven by the need to find safe, carbon-neutral and sustainable alternatives to the incumbent structural materials of the urban world. The market for these ideas is quite simply enormous. The proposed solutions have significant capacity to revolutionize the building industry to address the major challenges of climate change, urbanization, sustainable development and world housing needs.
