Summary
The objective of the current project is to develop a performance-based design process for wood-based design systems that would meet the objectives and functional statements set forth in the National Building Code of Canada. More specifically, this report discusses the fire and seismic performance of buildings, as identified as a priority in a previous FPInnovations report (Dagenais, C. (2016). Development of Performance Criteria for Wood-Based Building Systems).

Summary
Sustainable, safe, durable, cost-effective and efficient; wood is used across Canada in occupancy classes such as business, residential, commercial and assembly. In the United States, many mixed-use buildings have been designed as “podium” buildings; a wood structure bearing on a podium of noncombustible construction. The International Building Code includes provisions that allow wood buildings, often housing residential or business occupancies, to be constructed over a podium of noncombustible construction accommodating mercantile or assembly occupancies. The concept of a horizontal fire separation, acting to a certain degree as a “horizontal firewall”, was introduced in the International Building Code in the mid-2000s, allowing the podium to be considered a separate and distinct building from the wood structure that sits overtop. Since podium structures are becoming increasingly “à la mode” in the construction industry, integrating the horizontal fire separation concept into the National Building Code of Canada would allow the industry to benefit from the advantages of wood construction in mixed-use buildings At the request of FPInnovations, this technical report has been prepared as a guideline for the implementation of design provisions for wood podium buildings into the National Building Code of Canada. Various strategies, special considerations, and possible risks for fire safety in this type of building are explored.

Summary
Fire safety regulations impose very strict requirements on building design, especially for buildings built with combustible materials. It is believed that it is possible to improve the management of these regulations with a better integration of fire protection aspects in the building information modeling (BIM) approach. A new BIM-based domain is emerging, the automated code checking, with its growing number of dedicated approaches. However, only very few of these works have been dedicated to managing the compliance to fire safety regulations in timber buildings. In this paper, the applicability to fire safety in the Canadian context is studied by constituting and executing a complete method from the regulations text through code-checking construction to result analysis. A design science approach is used to propose a code-checking method with a detailed analysis of the National Building Code of Canada (NBCC) in order to obtain the required information. The method starts by retrieving information from the regulation text, leading to a compliance check of an architectural building model. Then, the method is tested on a set of fire safety regulations and validated on a building model from a real project. The selected fire safety rules set a solid basis for further development of checking rules for the field of fire safety. This study shows that the main challenges for rule checking are the modeling standards and the elements’ required levels of detail. The implementation of the method was successful for geometrical as well as non-geometrical requirements, although further work is needed for more advanced geometrical studies, such as sprinkler or fire dampers positioning.

Summary
An advanced modelling tool, WoodST, has been developed for fire safety analysis of timber structures. It is demonstrated that this advanced modelling tool can predict the structural response of LVL beams, glulam bolted connections, OSB-web I-joist and wood-frame floors under forces and fire conditions with an accuracy acceptable to design practitioners (i.e., within 10% of test data). The developed modelling tool can: Fill the gap in terms of suitable models for timber connections, which is an impediment for the design and construction of tall wood buildings; Provide a cost-effective simulation solution compared to costly experimental solutions; and Significantly reduce the cost and shorten the time for the development and/or optimization of new wood-based products and connections.

Summary
FPInnovations carried out a survey with consultants and researchers on the use of analytical models and software packages related to the analysis and design of mass timber buildings. The responses confirmed that a lack of suitable models and related information for material properties of timber connections was creating an impediment to the design and construction of this type of buildings. Furthermore, there is currently a lack of computer models and expertise for carrying out performance-based design for wood buildings, in particular seismic and/or fire performance design. In this study, a sophisticated constitutive model for wood-based composite material under stress and temperature was developed. This constitutive model was programmed into a user-subroutine which can be added to most general-purpose finite element software. The developed model was validated with test results of a laminated veneer lumber (LVL) beam and glulam bolted connection under force and/or fire.

Summary
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.

Summary
The main objective of this study is to evaluate the heat release rate and fire growth contribution due to heat delamination characteristics of CLT manufactured with four types of adhesives used for face bonding, when exposed to a constant radiant heat flux. The evaluation is performed using the principles of ISO 5660-1 “Reaction-to-fire tests - Heat release, smoke production and mass loss rate – Part 1: Heat release rate (cone calorimeter method)”. The American version of this test method is ASTM E1354 « Standard Test Method for Heat and Visible Smoke Release Rates for Materials and Products Using an Oxygen Consumption Calorimeter ». The long-term objective is to determine which currently accepted test methods allow for the most suitable evaluation of heat delamination characteristics of adhesives used in structural engineered wood products, based on their actual end-use applications (e.g. bending, compression, combined stress, cross-plies, etc.).

Summary
Recent architectural trends include the design and construction of increasingly tall buildings with structural components comprised of engineered wood referred to by names including; cross laminated timber (CLT), laminated veneer lumber (LVL), or glued laminated timber (Glulam). These buildings are cited for their advantages in sustainability resulting from the use of wood as a renewable construction material. Previous research has shown that timber elements contribute to the fuel load in buildings and can increase the initial fire growth rate – potentially overwhelming fire protection system and creating more severe conditions for occupants, emergency responders, and nearby properties. The overarching goal of this project Fire Safety Challenges of Tall Wood Buildings Phase 2 (involving five tasks) is to quantify the contribution of CLT building elements (wall and/or floor-ceiling assemblies) in compartment fires and provide data to allow comparison of the performance of CLT systems against other building systems commonly used in tall buildings.
