The influence of fire position on the neutral plane height was analyzed in order to analyze the smoke movement. One inner corridor building multiple openings was constructed by computational fluid dynamics (CFD) software and the airflow velocity and the pressure distribution under different fire position. The result shows that the influence of fire position on the height of neutral plane can be divided into two phases and the base height (Hb) is put forward as the critical values for the two phases. When the he height of fire (hf) is lower than Hb, namely hf< Hb, with the hf increasing, the neutral plane height increase is not significant. However, when the hf>Hb, with the fire height increasing, the neutral plane height increase significantly. Additionaly, in the condition, the position of neutral plane will be on the same level as that of the fire soucrce.
