Abstract

In this paper, the application of evacuation delay time (Cognition time + initiation time) and examine the degree of opening of fire doors in households for evaluating evacuation safety and suggest a realistic alternative. In order to proceed with this study, first of all, the preliminary investigation on evacuation safety evacuation of residential-type buildings (Apartment, urban living houses, etc.) among the performance-oriented design targets of Gwangju Metropolitan City, which was implemented until June 2018. Then, for the two representative types that are commonly used among the previously surveyed buildings, evacuation delay time is applied to W1, W2, and respectively simulating the opening of the doors is applied to th full open, 1/4 open, the leakage gap and evacuation safety evaluation was performed. As a result of evaluating evacuation safety was found that it is difficult to secure evacuation safety regardless of evacuation delay time W1 and W2 when the fire door is fully open and 1/4 open, Only when the leakage gap is applied evacuation safety was ensured even if evacuation delay time W2 was applied. Therefore, when a residential building is subject to performance-oriented design, evaluating the application of W2 rather than W1 is considered for evacuation delay time to reflect concern about privacy infringement due to CCTV installation, etc. In order to secure the Smoke blocking performance of the fire door and to improve the performance-oriented design, I would like to propose to consider the method of applying a leak gap to the degree of opening of the fire door. Through this, it is expected that the performance-oriented design will be a step further by performing evacuation safety evaluation with more realistic data.

본 논문은 주거형태를 가지는 건축물의 성능위주설계 시 수행되는 피난 지연시간(인지 시간 + 개시 시간)의 적용과 세대 내 방화문의 개방 정도가 피난 안전성 평가에 어떠한 영향을 미치는지 파악하고 현실적 대안을 제시하기 위한 논문이다. 본 연구를 수행하기 위해 먼저 2018년 6월까지 시행되었던 광주광역시의 성능위주설계 대상 건축물 중 주거형태를 가지는 건축물(공동주택, 도시형생활주택 등)의 피난 안전성 평가에 대해 선행 조사를 하였다. 그런 다음 선행 조사된 건축물 중 일반적으로 많이 사용되고 있는 2가지 대표적인 Type에 대해 피난 지연시간은 W1, W2를 적용하고 방화문의 개방 정도는 전체개방, 1/4 개방, 누설 틈새를 각각 적용하여 시뮬레이션한 다음 피난 안전성 평가를 수행하였다. 피난 안전성 평가의 수행결과 방화문 개방 정도가 전체개방 및 1/4 개방 상태에서 사생활 침해 등을 고려하여 피난 지연시간 W2를 적용한 경우에는 피난 안전성을 모두 확보하기 어려운 것으로 나타났으며, 누설 틈새를 적용한 경우에만 피난 지연시간 W2를 적용해도 피난 안전성이 확보되는 것으로 나타났다. 따라서, 주거형태를 가지는 건축물이 성능위주설계 대상이 될 때 피난 안전성 평가 수행 시 CCTV 설치 등으로 사생활 침해 등의 우려가 있는 국내 현실을 반영하여 피난 지연시간은 W1보다는 W2의 적용을 검토하고 방화문의 차연성능 확보 및 성능위주 설계의 고도화를 위해 방화문의 개방 정도에 누설 틈새를 적용하는 방안도 함께 검토해 줄 것을 제안하고자 한다. 이를 통해 성능위주 설계 시 좀 더 현실화된 자료로 피난 안전성 평가를 수행함으로써 한 단계 더 발전된 성능위주설계가 될 것으로 기대된다.
