Nowadays, high-rise buildings are emerging one after another, which also brings safety hazards, such as personnel density and aging of fire protection facilities possibly leading to fire hazards. Once a fire occurs carelessly, it will cause incalculable losses. Moreover, the complexity of the interior of buildings also poses great difficulties for personnel evacuation, hence it is particularly important to understand the hazards of building fires and establish reasonable evacuation routes in advance. This paper takes the high-tech building of Tianjin University as the research object. Based on BIM (Building Information Model) technology and Pyrosim, numerical simulation and visual analysis methods are used to establish a fire scene model. The required smoke detectors, temperature fields, visibility slice views, and other information are added to comprehensively analyze the building to obtain the data of smoke concentration, temperature, and the impact of CO content and visibility on personnel evacuation, as well as the reasonable evacuation time and evacuation routes. The functions above determine the value of BIM technology in high-rise building fire models, and provide important guidance for emergency command and personnel evacuation on fire sites.
