Abstract

Super high-rise buildings are characterized by high density of occupants and long vertical evacuation distance in staircases, which can easily cause congestion and lead to fatigue. Therefore, without effective evacuation guidance, crowding and trampling accidents are likely to occur in the vertical evacuation. Recently, intelligent guidance technology combining real-time monitoring on fire spread and personnel evacuation has become a research hotspot in the field of building safety evacuation. However, the focus of current research is on low-rise public buildings where horizontal evacuation is the main concern, and the existing intelligent guidance technology can hardly meet the demand for vertical evacuation in super high-rise buildings. This paper proposes five principles and a framework for the development of intelligent evacuation guidance systems in super high-rise buildings based on the digital twin technology. The system framework contains five dimensions: physical entities, virtual model, digital-twin data, optimization algorithm and application services, and can dynamically generate evacuation guidance paths for occupants based on the real-time situation of fire spread and people evacuation.
