北京奥运体育馆烟控系统性能化设计

Performance-based Design for Smoke Control System of Olympic Games Gymnasiums in Beijing

根据奥运体育馆的特点,指出了对于烟控系统采用处方式设计的不足之处,给出了对体育馆进行性能化的烟控系统设计的过程,论述了人员生命安全判定指标、火灾规模、清晰高度、烟控系统参数的确定问题,并对CFD软件进行模拟验证和优化时遇到的排烟量优化、控烟分区划分、补风设计、抽漏现象的避免,过烟孔设置等问题进行了深入研究。

This paper analyzes the shortcomings of smoke control system based on prescription code for Olympic Games gymnasiums. The process of smoke control system using performance-based design to gymnasiums is discussed, including how to choose parameters, such as tenability limits, design fire, clear height, and smoke control system. Also discussed are problems related to the use of CFD software, including optimizing volume of smoke extraction, smoke control zoning, air supply, how to avoid plughole, design holes used to send out smoke.
