大型商业购物中心中庭防火分隔与人员疏散

摘要

以某大型商业购物中心为工程案例,讨论中庭区域采用防火分隔玻璃加自动喷水灭火系统的分隔方法是否满足防火性能要求.采用性能化防火设计的思想,设定多个火灾场景,采用CFD方法计算相应的火灾动力学参数,并将计算的结果与人员疏散安全性能判据进行对比分析.研究结果表明,在保证设备有效运行的前提下,在该商业购物中心使用防火玻璃结合其他综合分隔方法作为隔断是可行的.%A case on whether fire separation method of the sprinkler system sandwiched between the fire-resistant glass in the a-trium of a shopping mall conformed to certain fire performance was studied. Using performance-based fire protection design I-deas, a few scenarios were designed to calculate the fire dynamic parameters by CFD method. The calculated results were compared with the evacuation safety performance criteria. The result showed that using fire-resistant glass as the separation in the shopping mall is practical with the assurance of the equipment in the effective operation.
