摘要：

This paper starts from the structure features and fire characteristics of an atrium building, and clarifies the importance of the mechanical smoke extraction system. The disadvantages of China's code about the smoke control system design in an atrium are analyzed. The influencing factors of the smoke removal efficiency is studied in this paper including smoke evacuation quantity, atrium shape coefficient, smoke exhaust this start-up time and heat release rate.The future research direction is put forward according to the conclusion.
