FDS Research on Smoke Control in the Stair Enclosure of a High-Rise Building Fire Event

The paper briefly reviewed the methods of smoke control in a high-rise building fire accident and the research status of this topic. It shows that the stair enclosure, which is almost the only path for the building occupants to safely egress the building during a fire event in a high-rise building, plays a very important role in the performance based design of a high-rise building. Four fire scenarios of a stair enclosure, namely no measure, natural ventilation, pressurization and dilution, are simulated by FDS. The simulation results are compared and analysis to obtain the optimal solution. The further studies also pressurizatioaddress.
