The whole evacuation of building fire personnel is always a research hotspot. However, in special occasions and conditions, evacuation to the first safety zone as soon as possible is a powerful way to ensure the safety of people’s lives, that is, the study of the phased evacuation of building is also of great practical significance. In this paper, the BuildingEXODUS software was used to establish the evacuation model, which mainly analyzed the influence and law of two physical factors on the evacuation of people from the room to the corridor: personnel density, personnel distribution in the corridor. In addition, MassMotion software was used to simulate and compare some conclusions under the same evacuation scene, aiming to study and compare the similarities and differences of the influence of the same physical factors on the phased evacuation of building under different simulation mechanisms.

The evacuation channel is an important way to connect the room and the security exit. This paper studies the impact of queuing behavior on the evacuation of people in the building channel. In this paper, Considering the factors of evacuation channel width, personnel density and speed, queuing form, different queuing queues, etc., using Massmotion software simulation. The research shows that for different queuing methods, the evacuation efficiency of queuing by shares is less affected by the width of the channel, there is a critical channel width for the evenly divided queues, and the evacuation efficiency of the different queuing queues is inconsistent; under different widths, the personnel density and speed have different evacuation efficiency Law of influence. The research in this paper can provide a certain reference for the design of building evacuation.
