Abstract
The key objective of this study is to analyze full-scale fire-resistance tests conducted on structural composite lumber (SCL), namely laminated veneer lumber (LVL), parallel strand lumber (PSL) and laminated strand lumber (LSL). A sub-objective is to evaluate the encapsulation performance of Type X gypsum board directly applied to SCL beams and its contribution to fire-resistance of wood elements. The test data is being used to further support the applicability of the newly developed Canadian calculation method for mass timber elements, recently implemented as Annex B of CSA O86-14.

Abstract
The present work aims at evaluating the combustibility characteristics (i.e. reaction to fire) of structural composite lumber (SCL) when tested in compliance with the cone calorimeter standard ISO 5660 [7, 8, 9]. More precisely, this study evaluates the heat release rate, total heat release, mass loss, effective heat of combustion, smoke obscuration as well as the presence of toxic gases when SCL products are tested in conformance with ISO 5660. Moreover, this study is solely focused on SCL elements that are thick enough to act as semi-infinite solids (thermally thick solids), as opposed to typical thin combustible finish products. Tests data are also compared to those obtained for visually-graded solid wood specimens of the SPF species group.

Abstract
These tests were performed to support the approval and construction of a tall wood building in Quebec City (13-storey). While a calculation methodology is provided in Chapter 8 (Fire) of the CLT Handbook [3], the Association des Chefs en Sécurité Incendie du Québec (ACSIQ), the Régie du bâtiment du Québec (RBQ) and other stakeholders requested these tests be performed so that they could witness the actual fire performance of the specified assemblies. As such, the main objective was to demonstrate at least a 2 h FRR of the CLT assemblies, which is the minimum required rating as prescribed by the National Building Code of Canada [4] for structural elements and fire separation walls of exit stair ways and elevators shafts in tall buildings (greater than 6 storeys). Numerous representatives from Quebec and Ontario were present for either one or both days of testing, including RBQ, the Cities of Montreal, Ottawa, and Quebec City as well as fire services personnel from Montreal, Ottawa and Gatineau. FPInnovations, Nordic, the Canadian Wood Council (CWC), and CHM fire consultants were also in attendance.

Abstract
Fire tests on a double egress fire door installed in two Cross Laminated Timber (CLT) wall panels were conducted. The purpose of the testing was to identify design consideration for detailing the interface between a 90 min. listed door assembly and a CLT wall with a 2-hr fire resistance.

Abstract
Fire tests on two unprotected 5-ply Cross Laminated Tmber (CLT) floors with pipe penetrations were conducted. The purpose of the testing was to evaluate concepts for detailing metallic and plastic pipe penetration firestops. Although the focus was on flame through performance, some temperature data was collected on insulated and uninsulated metallic pipes.

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
The fire resistance of cross-laminated timber (CLT) could be improved by treating the lamina with fire retardants. The major issues with this technology are the reduced bondability of the treated lamina with commercial adhesives. This study assessed several surface preparation methods that could improve the bondability and bond durability of fire-retardant treated wood  with  two  commercial  adhesives.  Four  surface  preparation  methods,  including  moisture/heat/pressure, surface planing, surface chemical treatment, and surface plasma treatment were assessed for their impact on the bondability and bond durability of lodgepole pine lamina. The block shear test results indicated that all surface preparation methods were somewhat  effective  in  improving  bond  performance  of  fire-retardant  treated  wood  compared to the untreated control wood samples, depending on the types of fire retardants and wood adhesives applied in the treatment process and bonding process. The selection of surface preparation, fire retardant, and wood adhesive should be considered interactively to obtain the best bond properties and fire performance. It may be possible to effectively bond the treated lamina with PUR adhesive without any additional surface preparation for the fire retardant used in the treatment at FPInnovations.

Abstract
FPInnovations launched a multi-year research project to measure mid- to high-rise wood buildings’ natural frequencies and damping ratios to expand the database and validate or adapt the existing equations to estimate the natural frequencies. Two high-rise wood buildings equipped with an anemometer and accelerometers are also being constantly monitored to study how the wind excites the building.

Abstract
The objective of this study is to evaluate the fire behavior of CLT manufactured with different types of SCL or lumber boards, namely with laminated veneer lumber (LVL), laminated strand lumber (LSL) and Trembling Aspen. The fire test data is also compared to those of CLT manufactured in accordance with ANSI/APA PRG-320 using solid-sawn lumber grades. More specifically, the study aims at evaluating the charring rates of this new generation of CLT panels as well as the impact of their manufacturing parameters.
