高层建筑走廊排烟效果分析

摘要

选取具有条形走廊的典型建筑模型,模拟机械排烟条件下的走廊排烟效果.考虑建筑物门、窗缝隙的渗风作用,排烟系统参数设定以GB 50045 - 95《高层民用建筑设计防火规范》为基础,讨论排烟量、单个排烟口、起火房间位置等条件对排烟效果的影响.%Representative building models with straight shape corridor was chosen to research smoke exhaust effect with mechanical exhaust. It takes osmosis of building doors and windows into account and parameters set up in mechanical exhaust are based on Code for fire protection design of high build ings. It mainly discussed the effect of airflow rate, only one vent and different position of fire room on mechanical smoke exhaust.
