摘要
依据《高层民用建筑设计防火规范》国家博物馆大广场中庭设计排烟量需达到160万m3/h。笔者利用性能化防火设计的方法对国家博物馆中庭内的防排烟系统进行分析设计,确保火灾时中庭内烟气在人员疏散完毕之前不会达到危险状态。结果表明,在消防设施正常工作的条件下,51万m3/h的排烟量可以将中庭内的烟气控制住,保证人员的安全疏散。
Complying with the fire code, the smoke volume flow of large atrium of national museum will reach to 1,600,000 m^3/hr. In this paper, smoke control of large atrium was designed to guarantee people egress by facilitating performance-based fire design method. As a result, under the condition of valid fire protection measures, an exhaust capacity flow of 510, 000 m^3/hr can effectively accomplish constant layer height and be valid for safety evacuation.
