Abstract: The issue of global climate change has become increasingly concerning due to the considerable impact of greenhouse gas emissions. Amongst the significant contributors to this phenomenon is the construction industry, which ranked among the top three sectors with the highest global energy demands (Ahmed et al., 2021). The energy consumption of this industry results in the substantial production of carbon dioxide. Therefore, timber structures have gained significant attention as a promising approach to mitigate this issue due to their low carbon footprint, enhanced energy efficiency, and environmental benefits (Cabeza et al., 2013). Despite the ecological benefits of using timber as a building material, its combustibility remains a pressing concern for fire safety in timber structures. Consequently, there is an imperative to investigate the behavior of timber structures in the event of a fire (White & Dietenberger, 2010). The project aims to create and test experimental models of timber panels in standard fire scenarios. Key observations include the onset time and rate of combustion and spread, gas concentration, flame and smoke shape, heat fire magnitude, and mass and form of the residue post-combustion, among other factors. Additionally, the PyroSim software model of the same panel will be constructed to simulate the panel's combustion behavior under parametric fire. The fireproofing material located beneath the panel will be utilized as a variable in the analysis. To assess the performance of timber-framed buildings under a standard fire, control simulations of large compartments with different settings, such as timber ceilings with protective materials, plain timber ceilings, and concrete ceilings, will be carried out. The outcomes of this study will inform recommendations for fire protection design in timber-frame buildings.
