The library fire load includes fixed fire load, mavable fire load and temporary fire load. The large library building's fire load density and scaling factor interval of evacuation numbers were put forward based on the measured and mathematical statistics, and the rationality of applying the conversion coefficient in the performance-based fire protection design af building was pointed out.%图书馆火灾荷载主要有固定式火灾荷载、活动式火灾荷载、临时性火灾荷载.通过实测与数理统计相结合的方式求出了大型图书馆建筑中火灾荷载密度与疏散人数换算系数区间,指出各换算系数在建筑性能化防火设计应用中的科学合理性.
