Evacuation Modelling and Smoke Management Strategies in Rapid Transit Facilities

Emergency ventilation in rapid transit stations presents interesting design challenges to fire protection engineers due to the wide range of station design characteristics and complexity of the analysis that is conducted. Requirements governing the design of these systems are addressed by various codes and standards, such as NFPA 130, and through this regulatory framework the performance of the system is required to be evaluated using engineering analysis.

Applications of CFD and Other Techniques to Large Fire Losses


 Empire Landmark Hotel

 1400 Robson St, Vancouver, BC V6G 1B9

The reconstruction of fire scenarios using modelling and other techniques is not new. Computational Fluid Dynamics (CFD) has been employed for some years now in the design of fire protection systems as part of the fire and life safety design of buildings, in particular smoke control. Property protection is also an important consideration, where large fires can have a devastating impact on business continuity and be the result of long and expensive legal enquiries.

CFD is now also used routinely in fire forensics, where knowledge of the fire risks and fire protection systems in such situations is essential in the analysis of the fire, and the forensic team has to bring different skill sets to the production of the forensic report. In these often detailed and complex cases, CFD may be but one component of the overall analysis, fitting into a wider probabilistic analysis. Here, event tree modelling can play a very important role, allowing the relative importance of various factors, e.g. sprinkler system failure, to be quantified. CFD may be employed as a ‘calibration’ tool, examining a sub-set of critical scenarios in detail.
