초록
본 연구에서는 공공 시설물을 대상으로 설치된 지진가속도 계측 시스템의 운영 효율성 개선을 위하여 지진 이벤트 신호 변환 및 처리 알고리즘을 개발하였다. 더불어 처리된 지진 가속도 시간이력의 분석을 통해 건축물의 안전성을 평가할 수 있는 평가 방법과 평가 기준을 제안하였으며, 테스트베드 건축물에 적용하여 그 작동과 활용성을 검증하였다. 이를 통해 지진 이벤트 계측자료의 분석 정확성을 확보하고, 지진재해 상황에서 재난 대응의 방향과 우선순위 판단을 위한 의사결정 지원자료로 활용할 수 있을 것으로 판단된다.
Abstract
In this study, develop the seismic acceleration measurement data conversion and signal processing algorithms for improve the operational efficiency of the seismic acceleration measurement system installed for public facilities. Through the analysis of the seismic acceleration time history data, the evaluation methods and criteria and evaluating the safety of buildings were proposed. The system was applied to the test bed building to verify its operation and usability. It is expected to be used as a decision making support data and determining the direction and priority of disaster response in the event of an earthquake.
