Abstract	Evacuation is the key aspect to fire performance-based design. In this paper, the landmark building in commercial center of Guangzhou Tianhe is chose for research, and the high-rise building evacuation model in fire scene is established based on Pathfinder. Combined the evacuation behavior and smoke spread velocity, temperature, CO concentration and visibility variation, it is found that: 1) The evacuation process clearly divided into two stages and the second phase plays a decisive role. In the middle stage of the process, as appropriate for induction and avoid congestion or choose to move a large space again depart from the export direction which is fit for people escape. 2) In the beginning stage, because of path planning, and according guidance mechanism combined with collision processing to control personnel movement speed, so the evacuation is slow. But as time goes on, the congestion reduces, the evacuation speed increase, also with the evacuation efficiency. Thus, induction of personnel evacuation must be implemented, and to ensure the smooth evacuation elevators in case of fire.
