A large number of super high-rise buildings have been built in many cities in China, which not only improve the urban land utilization, but also enhance the local reputation of cities. However, super high-rise buildings bring about many firefighting problems in the meantime, such as the accessibility of firefighters, safe egress, occupant staging and evacuation, stack effect in high-rise buildings, the increase of fire load, and the mixing of different types of occupants. Especially, the top portion of the super high-rise building can increase commercial property value for the developer because of its good landscape and attraction of business facilities such as sightseeing, dining, and meeting, but these activities might increase the difficulty of firefighting and rescue. In this paper, taking a super high-rise building close to 500 m as an example, the fire safety challenges of long evacuation time and long evacuation distance in the building were analyzed, and a comprehensive life safety analysis with fire simulation of the topping crown of the building for sightseeing and dining was carried out. The proposed life and fire safety strategy can meet both the fire safety design intend of the China fire codes and the basic requirements of safe egress in fire. The design method in this paper can be used as a credible reference to guide the design of special space at the top of similar super high-rise buildings in the future.
