Due to the limitations of function and beauty of the building, some fire fighting design scheme can no longer satisfy the fire fighting codes. Performance-based fire protection design method can provide technical scheme on the basis of scientific assessment of fire fighting. In this paper, a method based on the performance-based fire-protection design is used to simulate the evacuation in order to see whether it is safe in a long evacuation distance. And it also proves that adding shelters can ensure the safety of evacuation. Key words: commercial synthesis; performance-based fire protection design; evacuation distance; hallway refuge
