The Performance-based Design on a Smoke Extraction System of Construction with Large Area Space

This paper builds up an ideal market model,explains the principle of ventilating smoke according to the related conditions,chooses suitable smoke controlling methods,namely the combination of the natural smoke control and the machine smoke control.According to the calculation of the amount of smoke,the smoke air temperature,this paper offers designs reasonable of the smoke arch height,the width,the area of windows for ventilating smoke,etc.Meanwhile,it makes the suggestions for the rationalization to the position of the constitution oscula,the requisition of mounting of the smoke machine.
