Abstract: This paper takes a super-high building as an example, simulation software FDS and Pathfinder are used to verify the feasibility of its large atrium space fire design. At the same time, from the perspective of fire protection design and economy, this paper summarizes the existing problems of super-large atrium space in super-high buildings, and gives some suggestions for the future development of the atrium space in super-high buildings.

Key words: super-high building, large atrium, performance-based fire design
