Recently, several major incidents occurred in worldwide metro and subway systems due to inadequate or inappropriate emergency procedures. In this study, the traditional and innovative metro underground stations were analyzed utilizity the CFAST and FDS computer program. A comparative study has been conducted to evaluate the smoke descending rate, and temperature distribution, etc with addressable zoned smoke control system. Dynamic egress analysis was followed to validate the NFPA 130 which was taken as the design guidelines to evaluate the evacuation time using SIMULEX program. Finally, the smoke management design and egress system was integrated, which warrants its qpplication in actual engineering designs.

ABSTRACT Almost people hurt or die because of heavy smoke when the building fires. Smoke Management is to keep the smoke in the limited zone or to change its direction and to keep the ways which the people escape bright. It is convenient for fireman to save them and to keep their life and to reduce the money loss. In the developed country of the world, smoke management design is one of the most important factors to affect egress system of the building. Effective smoke management design is to avoid the smoke diffusing or descending and to make the people have enough time to escape. The combination of smoke management and egress system using performance-based fire safety design should be developed safely and economically. In Taiwan,we haven¡¦t the proper law of smoke management and egress system about the atria of the large space. So we must progress the computer simulation about smoke management and egress system and then use full-scale experiment to perform. The major terms of the content are: 1.the optimal distribution zone analysis of smoke management of the building. 2.to design and to analyze smoke management of the atria. 3.the combination of design analysis of smoke management and egress system. 4.full-scale experimental investigation. We hope that the performance-based fire safety design method about smoke management and egress system of the large shopping mall could be the excellent model and enchance the safety of the building in Taiwan.
