Long Island Railroad into Grand Central Terminal – East Side Access Project
Smoke Movement Modeling
皇家88账户注册个问题
The stations needed emergency ventilation and egress systems. Also, the peak fire size heat release rates for M-3 and M-7 rail car vehicles was unknown.
解决方案
We conducted a performance-based fire engineering study on the rail cars and determined that the windows in the vehicles were a key component to the growth of the fire. A materials hazard analysis of the rail vehicle window glass was conducted and incorporated into the analysis of the station smoke control system design. Comparative studies of smoke movement and occupant egress informed the design of the station egress and smoke control systems. We also used the (Hughes Post-Flashover and Decay) HAIPFD fire model to predict heat release of a rail car fire and Fire Dynamics Simulator (FDS) temperature data inputs into a Heat Transfer in Nine Geometrics (HEATING) calculation to determine the greatest exposure hazard from the rail car.
结果
穿过皇家88娱乐的火焰, smoke and egress modeling services, we helped East Side Access decrease the size of their smoke control system and overall required egress time, reducing overall construction costs while maintaining a compliant level of safety.
