摘　　要：针对某高层图书馆的防排烟系统分别进行处方式设计和性能化设计,运用FDS软件模拟各设计方案,通过对单层设计和整栋设计中温度、能见度、CO浓度等参数的变化规律的模拟,对比分析处方式设计和性能化设计对防排烟的影响。通过模拟与数据分析得出,走道增设防火卷帘能在一定程度上阻碍烟雾向前室与防烟楼梯间的蔓延速度,合理设置前室与防烟楼梯间的正压送风量效果要优于楼梯间单独加压送风(送风量比前者大)的防烟效果。A smoke control system for a high-rise library building was designed in a traditional prescriptive way and a performance-based way. Several design proposals were put forward in this paper. FDS software was used to simulate the change of the temperature, visibility and CO concentration of the single layer and the whole building. Based on the simulation and data analysis, the spread speed of smoke speading to smoke free lobby and smoke proof staircase could be reduced by setting fire resisting shutter on the path. The effect of setting positive pressure air supply system in both smoke free lobby and smoke proof staircase was proved better than just setting that in the latter（the latter owing larger air volume）.
