Study on Simulation Software of Personnel Safety Evacuation in Large Public Building Fire

It is very necessary to develop an evacuation model for improve fire protection design of public building. New evacuation model and new application software was developed in this paper. Four occupant types were considered in the model, which have there own personnel characters and can reflect their influence on evacuation. Behavior rules was established in the model, which can describe the normal purposeful movement of the people and can reflect the influence of crowd density. The fire data which was simulated by fire simulation software FDS can be loaded into the evacuation model in every compute step, which can describe the evading movement and the following movement of the people. By using this software, the user can obtain the personnel position at every compute step, the people quantities at every compute step and the dynamic escaping course of the people. The result of this paper will provide the theory basis for evaluating the escaping design, implementing the performance-based fire design, and guiding the fire rescue in the fire fighting.
