Performance Improvement of Smoke-Control System Using CONTAMW

In the event of a fire in building equipped with air-pressure smoke-control equipment, if system is operated closed door, then smoke discharge results difficulty opening door. this study, an optimal solution was devised to solve problem negative pressure generation corridors, and proposed verified using CONTAMW, numerical analysis program for smoke-retardant facilities. Thus, it confirmed that corridor could be resolved by installing flap automotive dampers between annex.
