Abstract

Purpose: The purpose of this study is to analyze the differential pressure and velocity to prevent smoke backflow of Stairways Apartment House fire, and verified the effectiveness of smoke velocity standards proposed by NFSC 501A. Method: The smoke control design of the stairways apartment house of the real model and the performance of the velocity to prevent smoke backflow according to the window opening conditions of the living room were analyzed using the CONTAM program. Result: Although the differential pressure performance of the apartment's smoke control system was satisfactory, it was found that Performance of velocity to prevent smoke backflow did not come out according to the opening condition of the living room window. Conclusion: In the case of Stairways Apartment House, it is necessary to review the method of making exceptions to the 'velocity to prevent smoke backflow' standard required by the National Fire Safety Codes(NFSC 501A)

연구목적: 본 연구는 계단식 공동주택의 화재 시 차압 및 방연풍속 특성을 분석하고, 화재안전기준에서 제시하고 있는 방연풍속 기준의 실효성을 검증하는 것을 목적으로 한다. 연구방법: 실제 모델의 계단식 공동주택의 제연설계 및 거실의 창문 개방조건에 따른 방연풍속의 성능을 CONTAM 프로그램을 이용하여 분석하였다. 연구결과: 공동주택 제연설비의 차압성능은 만족하더라도, 방연풍속 성능은 거실창문의 개방조건에 따라 방연풍속의 성능이 나오지 않음을 알 수 있었다. 결론: 계단식 공동주택의 경우 화재안전기준에서 요구하는 ‘방연풍속’ 기준에 대해 예외를 두는 방안의 검토가 필요하다.
