Abstract:

With the rapid development of economics in the Far East, many big construction projects were found. The new designs have difficulties to comply with the fire codes. Performance-based design (PBD) was then applied to determine fire safety provisions, particularly for underground subway stations in urban areas without much space.
Because of resources limitation, free software of Computational Fluid Dynamics (CFD) was applied in hazard assessment in many construction projects. No full-scale burning tests were carried out to justify the CFD predicted results. Authorities having jurisdictions (AHJ) are now more knowledgeable in fire science and engineering. CFD Results are starting to be challenged.
Common mistakes made in PBD projects with railway and subway systems based on CFD as pointed out by different parties including fire research workers, users, fire officers and journal paper reviewers will be discussed in this presentation.
