Fire dynamics inside a large and open-plan compartment with exposed timber ceiling and columns: CodeRed #01

Panagiotis Kotsovinos et al.

Summary: This study conducted a series of experiments in large compartments to investigate the performance of open-plan, exposed timber compartments during fires. The results showed that the timber structure significantly affected the heat release rate and smouldering combustion could continue for several hours.

Impact of ventilation on the fire dynamics of an open-plan compartment with exposed timber ceiling and columns: CodeRed #02

Panagiotis Kotsovinos et al.

Summary: This paper presents experimental evidence on the impact of reduced ventilation on fire dynamics in mass timber buildings. The findings show that reduced ventilation slows down the fire spread and burning rate, leading to longer fire duration. The flame spread rate is more affected in the mass timber than in the fuel load.

Fire Experiment Inside a Very Large and Open-Plan Compartment: x-ONE

Egle Rackauskaite et al.

Summary: Traditional design fires in structural fire engineering were developed based on small-scale experimental compartments, while modern large open-plan buildings present non-uniform fire conditions. Further research and experiments in large compartments are needed to understand fire dynamics and enhance the safe design of modern buildings.

Large-Scale Enclosure Fire Experiments Adopting CLT Slabs with Different Types of Polyurethane Adhesives: Genesis and Preliminary Findings

Danny Hopkin et al.

Summary: This paper examines the fire performance of exposed cross-laminated timber (CLT) in large enclosures. Three experiments involving propane-fuelled burners and different ceiling types were conducted. The results show that the exposed CLT had a higher initial rate of heat release compared to non-combustible lining, but stabilized at approximately one and a half times the non-combustible lining after charring. Premature char fall-off was observed near the burners when using standard polyurethane adhesive. However, both exposed CLT ceiling experiments experienced auto-extinction of flaming combustion when the burners were switched off.

Fire dynamics in mass timber compartments

Carmen Gorska et al.

Summary: With the introduction of Engineered Wood Products in the construction industry, fire safety concerns have arisen especially for high-rise buildings. The combustible nature of timber suggests that existing compartment fire dynamics models may not be applicable to compartments with timber boundaries. Experimental data shows that the presence of timber in compartments increases gas flow velocities, leading to a transition in fire behavior.
