A Study on the Protection of Smoke Control Performance in Building Enclosure to Prevent the Expansion of Smoke in Fire

화재시 연기확대 방지를 위한 건축물 구획공간에서의 방연성능 확보에 관한 조사 연구

In case of fire in a compartmentalized building area, a number of casualties are caused by smoke production. Accordingly, openings, penetrations and joints in compartmentalized spaces should be secured not only for fire resistance but also for smoke-proofing. However, domestic test regulations stipulate test methods for refractory performance of penetrations and joints, but do not specify separate deferral performance. In the case of openings, the test for the smoke performance exists at room temperature, but the smoke performance at high temperature is not secured, so countermeasures are needed.
