fire & smoke modeling

With building designs becoming more complex, understanding the effects of fire on the structure and occupant safety is critical.

Using the Fire Dynamic Simulator (FDS) program developed by NIST, FSC can create a model to predict the effect of fire and smoke in different “what if” scenarios. The FDS program represents state-of-the-art approaches currently available for evaluating life safety characteristics of a building.

Using a computational fluid dynamics method, this model requires extensive time and expertise to set up and run — but produces results that are much more detailed than the simpler approximations used for code-required analyses. With this program, FSC can calculate the effects of fires on structural elements with its heat transfer models (i.e. when the temperature rises in items like columns and beams, it can be calculated with a high-degree of fidelity and will provide information useful in determining alternate approaches to meeting code requirements for building fire resistance).

FSC may also use fire and smoke modeling to determine if the occupant will be able to exit the building or room in an acceptably-safe atmosphere.

A computer simulation can be used to determine if tenable conditions are maintained throughout the time required for egress as an alternative or performance-based approach to the exiting requirements of the building code.  Tenability criteria, which is based upon temperature and gas concentrations, are examined as the benchmark of acceptability.

Fire & Smoke Modeling is best suited for use in evaluating irregular, complex spaces such as atriums, large assembly buildings, and even enclosed parking garages.
