- Abstract
- [ABSTRACT IN ENGLISH] To ensure the safety of human life in buildings on fire, the system that combines the accommodation for evacuation and smoe control should be established for the design and estimation of building safety. This paper describes the summary of a steady state analysis of smoke movement in buildings on fire and its computer program. Also described are the results of analysis of eight different cases. In the case of tall buildings such as the ones studied, it has become clear that the smoke flow between the stairwell of a main escape route and the corridor was influenced greatly by the following: 1) opening conditions and height of the top opening of the stairwell; 2) temperature difference between the stairwell and the outside of building. In the case of separation room pressurization system which is one of the methods of controlling smoke, it has been found that required air supply rate is influenced immediately by the folowing: 1) opening ratio of the separation room door; 2) temperature difference between the stairwell and the outside of the building.
