The current study aims at evaluating the integrity failure (i.e. passage of hot gases or flames through the assembly) of CLT assemblies connected together using four types of commonly used panel-to-panel joints when exposed to the standard CAN/ULC S101 “Standard Method of Fire Endurance Tests of Building Construction Materials” [1] fire resistance time-temperature curve. The four types of joints include: 1) half-lapped, 2) internal spline, 3) single surface spline and 4) double surface splines. 301009649
En novembre 2014, le Ministère soutenait la réalisation d’un incendie de démonstration à grande échelle effectué dans les installations du Conseil national de recherches du Canada (CNRC). L’incendie de démonstration a été réalisé afin d’appuyer un projet de construction d’un immeuble de grande hauteur à Québec. Le but était de démontrer la façon dont une structure massive en bois pouvait résister à des conditions sévères d’exposition au feu d’au moins deux heures. La structure consistait en une gaine verticale de construction massive en bois conçue pour un ascenseur ou un escalier de sortie.
L’incendie de démonstration a été réalisé par une équipe composée de FPInnovations, Nordic Bois d’ingénierie, GHL Consultants, la firme Technorm et du CNRC.
In November 2014, the Department supported the conduct of a large-scale demonstration fire at the facilities of the National Research Council of Canada (NRC). The demonstration fire was carried out to support a high-rise building construction project in Quebec City. The aim was to demonstrate how a massive wooden structure could withstand severe fire exposure conditions of at least two hours. The structure consisted of a vertical shaft of massive timber construction designed for an exit elevator or staircase. The demonstration fire was carried out by a team made up of FPInnovations, Nordic Engineered Wood, GHL
There is a need to evaluate TCC systems under fire conditions to understand how shear connectors will perform and might affect the fire performance and the composite action of the assembly. This project evaluates the fire performance of TCC assemblies based on their structural resistance, integrity and insulation when exposed to a standard fire, as well as how mass timber and concrete interact. This study involves full-scale fire resistance tests on composite wood-concrete floors using two types of shear connectors. 301009649
