With the development of economy and society and the growth of population, the high-rise and multi-function of commercial buildings have become an international trend. But it also poses huge fire hazards. Most of the existing studies' research objects are predominantly high-rise residential buildings, without considering the impact of different functional zones (Standard floor, entertainment zone, office zone, equipment room and so on) and personnel distribution of commercial buildings evacuation. And the influence of using elevators to carry evacuees on the refuge floor on personnel evacuation is rarely studied. In this work, the fire scenario of the Yangtze River International Conference Center, a high-rise commercial building, is simulated with the Pyrosim program to get the necessary parameters under various fire scenarios and to calculate the available evacuation time T ASET . At the same time, according to the complex functional zone of the commercial high-rise building and the distribution of people in different time periods, a reasonable evacuation strategy is developed and simulated by Pathfinder software. The results indicate that unorganized evacuation will lead individuals to take the erroneous evacuation route, resulting in a vast region of congestion; comprehensive consideration of the time staggering and the reasonable distribution of evacuation routes can significantly improve evacuation efficiency, and the T RSET of night and working hours is 36.6%-55.3% and 49.9%-79.6% of unorganized evacuation, respectively. For the night fire, 60% of the people use elevator-refuge floor to evacuate is the optimal strategy; for the fire during working hours, half of the people on standard floors use the elevator to evacuate and people on multifunctional floors evacuate in four batches is the best plan. The results of this study can provide viable solutions and a foundation for analyzing the fire evacuation and safety of big commercial high-rise buildings.

“…Compared with general building fires, super high-rise building fires have unique characteristics [10]: (1) fire spreads quickly, (2) super high-rise buildings have numerous fire hazards, (3) complex building structures and boundary environments cause particular fire evolution behaviors, (4) crowd evacuation in super high-rise buildings is a major safety concern, (5) fire rescue is difficult and the amount of time required to fight a fire is long, allowing the fire to readily spread, and (6) fires cause substantial loss and grave social consequences. erefore, identifying methods for effectively preventing the occurrence, development, and spread of fire in super high-rise buildings, ensuring safe evacuation of internal personnel, and reducing casualties and property damage have become crucial concerns in the field of firefighting [11][12][13][14][15]. In the current research on highrise building fires, NFPA92B is the most widely recognized and used.…”

Research on fire spread in super high-rise buildings is crucial for identifying feasible methods of fire prevention and personnel evacuation. In this study, a fire spread model was established based on the fire dynamics simulator (FDS), and fire spread results were analyzed for a fire scenario in a single room under different conditions, a fire scenario in different functional places under the same conditions, and the spread of fire outside of the room. The results revealed that the critical time required for a fire to become a safety hazard in a shop, a restaurant, or an office was approximately 200 s. The same type of fire reached the critical time required for a fire to become a safety hazard more quickly in an office than a restaurant or shop, regardless of whether the fire spread was caused by CO mass fraction or temperature. More attention should be paid to fire safety in office spaces in super high-rise buildings. Furthermore, compared with CO mass fraction and temperature, visibility was a more influential factor in determining the critical time required for fire to become a hazard, and smoke affected the adjacent open area in approximately 60 s. In the event of a fire, the temperature of the staircase and its front chamber was always lower than the threshold temperature of 60°C for human body tolerance.
