Fire Spread in Multi-Storey Timber Building, a CFD Study

The purpose of this paper is to investigate the fire performance in a multi-storey cross-laminated timber (CLT) structure by computational fluid dynamics (CFD) technique using Fire Dynamics Simulator (FDS v.6.7). study investigates temperature, heat release rate (HRR), and gas concentration (O2, CO2). importance research ensure that buildings adequate for occupant safety property protection. Moreover, proposed provides measures advance engineers when designing with sufficient protection predicting time flashover behaviour. present numerical modelling designed represent 10-storey CLT residential building where each floor has an apartment 9.14 m length width dimensions. pyrolysis model was performed thermal kinetic parameters furniture, wood cribs were allowed burn themselves simulation. This based on full-scale experiment two-storey building. results validated comparing them experimental data. Numerical simulation models show very close accuracy benchmark paper. CFD tools such as FDS can be used scenarios buildings.
