Abstract

The domestic earthquake-resistant regulation was legislated firstly in 1988. However, The magnitude and frequency of earthquakes has been risen in South Korea. Therefore, the mandatory target of earthquake-resistant has been expanded. The earthquake-resistant rates of public facilities have been increased by 58.3%. On the other hand, education facilities are low with 24.8%. For the reason, more than 50% of the educational facilities are expected to be damaged by the earthquake. Especially, the 45% of educational facilities were damaged at Po-Hang earthquake. As a result, the importance of the seismic retrofit for applying existing education facilities was ended up attracting people's interesting. In this respect, in order to develop a effective seismic retrofit method, many researchers have been conducted researches and it is expected to be actively carried out in the future. However, it is insufficient to consider that how far technology has been developed. Therefore, the purpose of this study is a comparative analysis of precedent guidelines in regard to seismic retrofit applying existing education facilities between domestic and other countries. Finally, the directions of future research are suggested.

국내 내진규정은 1988년에 최초로 제정되었으나 국내에서 발생하는 지진의 규모와 발생빈도가 증가하면서 내진 의무대상을 지속적으로 확대시켜왔다. 공공 시설물의 내진율은 58.3%로 증가한 반면에 교육 시설물의 내진율은 24.8%에 그치고 있는 실정이다. 이로 인해, 지진발생 시 국내 교육시설물의 50% 이상이 대규모피해를 받을 것이라 예측되고 있다. 실제로 포항지진에 의해 발생한 피해는 45%가 교육시설물로 나타남에 따라 국내 기존 교육시설물에 대한 내진 보강은 국민들의 주요 관심사가 되었다. 보다 효과적인 내진 공법을 개발하기 위하여 국내의 많은 연구자들이 연구를 수행해왔으며 앞으로도 활발히 진행될 것으로 예상된다. 하지만, 국내 기술의 발전이 어느 정도까지 이루어졌는가에 대한 고찰은 부족한 실정이다. 이에 본 연구에서는 국내 외 기존 교육시설물의 내진에 대한 가이드라인을 비교 분석하고 향후 연구 방향을 제언하고자 한다.
