우리는 21세기 하이테크(hightech) 시대에 살고 있다. 산업화의 발달로 우리는 물질적 기술적 진보에 따른 인구이동으로 인하여 시설의 쏠림 현상으로 거대도시(metropolis)를 넘어 거대도시권(megalopolis)이 형성되어 건축물의 초고층화, 지하화(지하철, 쇼핑센터 등), 대형화를 이루면서 주거문화 역시 바뀌었다. 인구의 과밀화 속에서 핵가족화 및 1인가구의 증가로 아파트 및 도시형 생활주택이 제도적 안전규제보다 빠른 속도로 확대되어왔다. 본 연구에서는 아파트화재 사례를 통해 시사하는 점을 분석하고, 아파트 실물화재실험을 통해 공동주택(아파트)화재 연소성상을 연구하였다. 그 결과 화재 사례분석 결과와 같이 발코니 확장형 아파트 보다 발코니 비확장형 아파트가 화재 연소의 확산 속도를 줄여주는 것으로 검증 되었다. 사례 및 실험 결과를 근거하여 공동주택 화재 안전대책 및 대응시스템이 개선되어야 한다.
We are living in the 21st century, a new era of high-technology. Due to movements in population towards certain preferred areas, caused by material and technological advancement, growth has occurredn beyond the metropolis, leading to the development of the so-calleda "megalopolis." This development has changed the culture of housing, notably the characteristics of high-rise buildings, and underground facilities (such as subways and shopping centers), and has generally enlarged the scale of the facilities. Due to the increase in the number of single-family households, - notably ones including only the nuclear family, there has been a growing overpopulation problem, with apartments and urban housing developments expanding at rates beyond institutional safety regulations. In this study, we analyze the phenomenon of fire spreading in apartment buildings through actual apartment fire case studies, including that of the MunjonPonpuri apartment building. It was found that the speed at which the fire spreads is lower in apartments without than in those with an extended balcony. Based on the findings from case studies and the test results, we propose a series of safety countermeasures and responses for apartment fires.
Key Words: Nonexpanded balcony, Extended balcony, Response system, Apartment fire safety
