Abstract

Many school buildings are not applied seismic code because of small size structures. But it must be designed to show enough structural performance when subject to earthquake due to the fact that most of school buildings are generally used as public shelters when the natural disasters. In this study, the seismic risk of the reinforced concrete school building structure which is the most common types of school structures was evaluated by using the seismic performance evaluation methods. As a result, model structures don't have enough seismic performance.

대부분의 학교 건물은 내진설계기준이 적용되기 이전인 1988년 이전에 설계되었으며, 이후에 지어진 학교의 경우도 내진설계 적용대상에서 제외된 5층 이하의 건물로서 내진성능이 없을 것으로 판단된다. 건물의 특성상 많은 아이들이 밀집하여 있고, 재난 시 대피시설로 이용된다는 점에서 학교 건물의 내진성능보유는 특히 중요하다. 본 연구에서는 우리나라 학교건물의 대표적인 유형을 모델구조물로 선정하여 학교건축물에 대한 내진성능 평가를 수행하였다. 보유강도와 보유성능을 기초로 내진성능을 평가한 결과 모두 내진성능이 미흡한 것으로 나타났다.
