Summary
In this project, CUrisk was employed to assess and compare the risk-to-life due to fire in mid-rise and high-rise residential and office buildings of wood construction and of non-combustible construction and to demonstrate how fire protection measures can be tuned to ensure a mid-rise or high-rise building of wood construction is as safe as a similar building of non-combustible construction. The computation results show that [...] Comparisons between the numbers of deaths and injuries of scenarios with and without suitable fire protection systems show the importance of fire protection systems in reducing life risk from fire in all buildings. Sustaining the reliability of fire protection systems through proper design, installation, inspection, and maintenance is important to achieve the life safety objectives.

Summary
This paper summarizes the experimental results from a series of tests that investigated the performance of timber-to-steel tensile connections exposed to fire. A series of fire-resistance tests were conducted on bolted wood-steelwood and steel-wood-steel connections loaded in tension. Each specimen had different cross-sectional area, fastener diameter, fastener spacing, edge distance, and tension load. The fire temperature profile produced by the furnace used both the standard time-temperature curve CAN/ULC-S101 and a non-standard time-temperature curve based on previous studies done at Carleton University. Results showed that the wood-steel-wood specimens had a longer time to failure than steel-wood-steel specimens with the same dimensions. The heat transfer and structural modeling portion of this research is currently underway using three-dimensional finite-element models.

Summary
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 to compare it to the performance of more traditional construction methods. Results show that the CLT panels when left unprotected get involved in the room fire as part of the combustible contents, responsible for over 60% of total heat release in the fully unprotected CLT room and double the heat release rate of a fully protected room fire where the CLT does not contribute. Partially-protected CLT rooms also demonstrates various levels of fire contribution. The amount of CLT exposure is also related to the occurrence of re-ignition and a second flashover after all the movable fuels are consumed. The behaviour of CLT delamination and charring as well as the performance of gypsum boards in fire are also discussed.
