- Abstract
- For the purposes of personal safety from the hazard of smoke in building fires, it is necessary to keep escape routes clear of smoke or to keep the smoke concentration on the routes thinner than allowable one until the evacuation of the occupants is completed safely. for this, it is naturally required to control smoke movement by some means. there should be a need for some design system, so claled "smoke protection design system", to plan the reasonable and effective system suitable for every building to secure occupants from the hazard of smoke. Some calculaiton to estimate smoke movement or to evaluate smoke control methods will be indispensable to the design system. This paper presents a fundamental concept of the smoke protection design system, computer techniques for calculating smoke movement and computed results of sample buildings.
