There is a need to evaluate timber-concrete composite (TCC) systems under fire conditions to understand how shear connectors will perform and might affect the fire performance and the composite action of the assmebly. 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 wood-concrete composite floors using two types of shear connectors.
A full-scale demonstration fire was conducted at National Research Council Canada (NRCC) to show that a 2-hr non-standard severe design fire in an apartment would have little or no effect on an adjacent elevator or stair shaft. The test was performed to support the approval of an alternative solution for a deemed-to-satisfy 2-hr...
The objective of the two tests described in this report was to evaluate the performance of cross-laminated timber (CLT) and nail laminated timber (NLT) construction protected with two layers of %-in. (16-mm) type X gypsum board when exposed to the therma...
FPInnovations is involved in a large research project regarding CLT construction. One objective
of this research is the creation of a design methodology for calculating the fire-resistance of CLT
assemblies/construction. This methodology will foster the design of fire-safe buildings of wood
or hybrid construction. In order to establish such calculation methods, a series of experimental
tests has been undertaken. A total of eight full-scale CLT fire resistance tests have been
conducted at the NRC fire laboratory where the panels were subject to the standard ULC S101
 fire exposure. The series consisted of three wall and five floor tests. Each test was unique
using panels with a different number of plies and varying thicknesses. Some of the assemblies
were protected using CGC Sheetrock® FireCode® Core Type X gypsum board while others
were left unprotected.
This paper documents the findings of a series of full-scale room fire tests, which includes tests on fully protected, partially protected CLT rooms as well as light-frame timber/steel rooms under real natural fires, aiming to investigate the fire behaviour and performance of CLT panels as an increasingly popular engineered wood product and...
