摘要
以某会展中心中庭区域的防火玻璃隔断材料是否满足防火性能要求为工程案例,采用性能化防火设计的思想,设定了四个最不利的火灾场景,针对这四个火灾场景采用CFD方法,计算防火玻璃材料表面温度和辐射热流两个火灾动力学参数,并将计算的结果与安全性能判据进行对比分析。研究结果表明,在该会展中心使用防火玻璃材料作为隔断是可行的,但必须确保消防设施的有效性。
A case on whether the fire glass separgtion in the atrium of a exhibition center conformed to certain fire performance was studise. Four worst scenarios were designed to calculate the surface temperature and radiation flux of the fire glass separation by CFDmethod. The calculated result was compared to the performance criteria. The result showed that using fire glass as the separation in the exhibition center is practical,but the effectiveness of its fire equipment should be ensured.
