Advanced Simulations For Building Design – Best Practice and Future Developments

January 26, 2017
Advanced simulations are becoming a common approach for dealing with complex fire safety problems. The use of specially developed software for fire and evacuation modeling allows fire safety problems to be solved in a way that was not possible just a few decades ago. Read More...

The Challenge of Maintaining FDS and CFAST

December 23, 2016
The Fire Dynamics Simulator (FDS) has been in the public domain for 16 years, and the zone fire model CFAST (Consolidated Fire and Smoke Transport) has been around, in one form or another, for nearly twice that long. While both are widely used and well regarded within the fire protection community, most end users do not fully appreciate the challenge of their maintenance and upkeep. Read More...

Simulating Hospital Evacuation

December 16, 2016
In hospitals, evacuation of those with severe movement impairments can be highly problematic – for the patients, for the staff and for the other evacuees. It is critical to understand the performance of horizontal and vertical evacuation strategies, including the means by which people with reduced mobility can be assisted in stair descent. The work presented herein quantifies the performance of trained hospital staff in evacuating people with reduced mobility and specifies algorithms to explicitly represent the dynamics of these devices within evacuation models. Read More...

FEMTC 2016: Circulation, Ingress, and More

September 13, 2016
Circulation movement is often a critical part of the analysis for high occupancy areas with lots of foot traffic. As research and technology improves, engineers are adding non-evacuation investigations to their résumés. Jennifer Wiley, a Fire Protection Engineer at Jensen Hughes, will discuss these other uses for people movement models at the Fire and Evacuation Technical Modeling Conference (FEMTC).  Read More...
