Abstract

Recently, there is a growing interest on sustainable connection system that makes it possible to reuse of main structural members by concentrating most of the damage in the frame caused by strong horizontal force, such as earthquake, to damper. In this study proposed a new type of damage-controlled connection system applying these concepts and analysed the major structural performance of the proposed system through the full-scale cyclic loading test and nonlinear finite element analyses. According to the result, it derived the optimal damper/beam strength ratio that minimize the damage of main members and satisfy at least the fully plastic moment of the beam. And it was to verify the possibility of applying as seismic connection details.

최근 지진동과 같은 강한 수평력 작용시 골조에 작용하는 대부분의 손상을 댐퍼부에 집중시키며 주부재의 재사용을 가능하게 하는 지속가능형 접합부 시스템에 관한 관심이 커지고 있다. 본 연구에서는 이러한 개념을 적용한 새로운 형태의 손상제어형 접합부 시스템을 제안하고 실물대 반복이력실험 및 비선형 유한요소해석을 통하여 제안 시스템의 주요 구조성능을 분석하였다. 분석결과를 통하여 주부재의 손상을 극소화하면서 보의 전소성모멘트 이상을 만족하는 최적의 댐퍼/보 내력비를 도출하였으며 내진접합상세로서의 적용가능성을 확인하였다.
