Abstract
Neither the National Building Code of Canada (NBCC) [1], nor any provincial code, such as the British Columbia Building Code (BCBC) [2], currently provide “acceptable solutions” to permit the construction of tall wood buildings, that is buildings of 7 stories and above. British Columbia, however, was the first province in Canada to allow mid-rise (5/6 storey) wood construction and other provinces have since followed. As more mid-rise wood buildings are erected, their benefits are becoming apparent to the industry, and therefore they are gaining popularity and becoming more desirable. Forest product research has now begun to shift towards more substantial buildings, particularly in terms of height. High-rise buildings, typically taller than 6 storeys, are currently required to achieve 2 h fire resistance ratings (FRR) for floors and other structural elements, and need to be of non-combustible construction, as per the “acceptable solutions” of Division B of the NBCC [1]. In order for a tall wood building to be approved, it must follow an “alternative solution” approach, which requires demonstrating that the design provides an equivalent or greater level of safety as compared to an accepted solution using non-combustible construction. One method to achieve this level of safety is by ‘encapsulating’ the assembly to provide additional protection before wood elements become involved in the fire, as intended by the Code objectives and functional statements (i.e., prolong the time before the wood elements potentially start to char and their structural capacity is affected). It is also necessary to demonstrate that the assembly, in particular the interior finishes, conform to any necessary flame spread requirements. The Technical Guide for the Design and Construction of Tall Wood Buildings in Canada [3] recommends designing a tall wood building so that it is code-conforming in all respects, except that it employs mass timber construction. The guide presents various encapsulation methods, from full encapsulation of all wood elements to partial protection of select elements. National Research Council Canada (NRC), FPInnovations, and the Canadian Wood Council (CWC) began specifically investigating encapsulation techniques during their Mid-Rise Wood Buildings Consortium research project, and demonstrated that direct applied gypsum board, cement board and gypsum-concrete can delay the effects of fire on a wood substrate [4]. There is extensive data on the use of gypsum board as a means of encapsulation for wood-frame assemblies and cold-formed steel assemblies. However, tall wood buildings are more likely to employ mass timber elements due to higher load conditions, requirements for longer fire resistance ratings, as well as other factors. There is little knowledge currently available related to using gypsum board directly applied to mass timber, or in other configurations, for fire protection. Testing performed to date has been limited to direct applied Type X gypsum board using standard screw spacing, and showed promising results [5, 6, 7]. This represents an opportunity for other configurations that might provide enhanced protection of wood elements to be investigated. Being able to provide equivalent fire performance of assemblies between non-combustible and combustible construction will thus improve the competiveness of tall timber buildings by providing additional options for designers.

This report addresses serviceability issues of tall wood buildings focusing on their vibration and sound insulation performance. The sound insulation and vibration performance may not affect the building’s safety, but affects the occupants’ comfort and the proper operation of the buildings and the function of sensitive equipment, consequently the acceptance of the midrise and tall wood buildings in market place. Lack of data, knowledge and experience of sound and vibration performance of tall wood buildings is one of the issues related to design and construction of tall wood buildings. The measured and estimated values should also be correlated with actual experiences of the occupants in the building if such information is obtained, for example, through a survey.

Abstract
Serviceability performance studied covers three different performance attributes of a building. These attributes are 1) vibration of the whole building structure, 2) vibration of the floor system, typically in regards to motions in a localized area within the entire floor plate, and 3) sound insulation performance of the wall and floor assemblies. Serviceability performance of a building is important as it affects the comfort of its occupants and the functionality of sensitive equipment as well. Many physical factors influence these performances. Designers use various parameters to account for them in their designs and different criteria to manage these performances. Lack of data, knowledge and experience of sound and vibration performance of tall wood buildings is one of the issues related to design and construction of tall wood buildings. survey.

Abstract
For wood floor systems, their vibration performance is significantly dependent on the conditions of their supports, specifically the rigidity of the support. Detrimental effects could result if the floor supports do not have sufficient rigidity. This is special ture for floor supporting beams. The problem of vibrating floor due to flexible supporting beams can be solved through proper design of the supporting beams. However, there is currently no criterion set for the minimum requirement for floor supporting beam stiffness to ensure the beam is rigid enough. Designers’ current practice is to use the uniform load deflection criteria specified in the code for designing the supporting beams. This criterion is based on certain ratios of the floor span (e.g. L/360, L/480 etc.). The disadvantage of this approach is that it allows larger deflections for longer-span beams than for shorter beams. This means that engineers have to use their experience and judgement to select a proper ratio, particularly for the long-span beams. Therefore, a better vibration-controlled design criterion for supporting beams is needed. It is recommended to further verify the ruggedness of the proposed stiffness criterion for floor supporting beams using new field supporting beam data whenever they become available.

Abstract
Le faible poids des produits en bois lamellé-croisé (CLT) combiné à leur degré élevé de préfabrication, ajoutés à la nécessité de fournir des produits de substitution à base de bois à l’acier et au béton, ont sensiblement contribué au développement des produits et des systèmes de CLT, tout particulièrement en ce qui a trait aux bâtiments de moyenne hauteur (5 à 9 étages). Tandis que ce produit est bien établi en Europe, la mise en place des produits et des systèmes de CLT en est à ses débuts au Canada et aux États-Unis. L’efficacité structurale du système de plancher agissant comme diaphragme et celle des murs en matière de résistance aux charges latérales dépend de l’efficacité des systèmes de fixation et des détails de connexion employés pour relier différents panneaux et assemblages. De longues vis autotaraudeuses sont généralement recommandées par les fabricants de CLT et sont utilisées pour relier les panneaux entre eux dans la construction de planchers ainsi que pour les assemblages plancher/mur. Cependant, il existe d’autres éléments et systèmes de fixation traditionnels et innovateurs qui peuvent être employés dans les assemblages de CLT. Ce chapitre met l’accent sur quelques systèmes de connexion qui reflètent les pratiques actuelles, certains étant conventionnels, d’autres étant brevetés. En raison de l’introduction récente du CLT sur le marché de la construction, on s’attend à ce que de nouveaux types de connexion soient développés au fil du temps. Une variété de questions liées à la conception des connexions spécifiques aux assemblages de CLT y sont présentées. L’approche de conception européenne est présentée et l’applicabilité des dispositions de conception de la norme CSA O86-09 pour les fixations traditionnelles du CLT telles que les boulons, les goujons, les clous et les vis à bois sont passées en revue et des lignes directrices sont également fournies. L’information fournie dans ce chapitre est dédiée aux concepteurs canadiens, un groupe ayant exprimé un vif intérêt pour la spécification des produits de CLT dans les applications non résidentielles et multi-étagées. Cependant, d’autres études seront nécessaires pour aider les concepteurs dans le développement de normes de conception et de procédures conformes aux normes canadiennes de conception des matériaux et au code national du bâtiment du Canada (CNBC). L’information technique sera également employée pour faciliter l’acceptation des produits de CLT en Amérique du Nord
