고층 주거건물에서 저층부 출입문 개폐 상태에 따른 연돌효과 변화에 관한 연구

This Paper is to describe a variation in stack effect due to the status of the openings on the lower floor used as a main entrance in high-rise residential building. The 46th floor residential building was tested in the various conditions of door opening in lobby, basement 1st and 2nd floor to see what the difference in stack effect take place when people are moving in the building. The results of the test show that the differential pressure between elevator shaft rise as the door is opened according to the air-tightness of the outside wall and the effect to the adjacent floor is relatively small.
