초록
본 연구에서는 NFPA 13을 참조하여 구조물 2층을 구현한 강재지그를 제작하였으며, 그루브 조인트의 배관연결재가 적용된 배관계통을 구성하고 정적 반복가력에 의한 지진모사실험을 수행하였다. 지진모사실험은 엑츄에이터로 건축물 내진설계기준의 최대허용 층간변위에 대한 반복가력실험을 수행하였다. 지진하중 발생 시 입상배관의 구조물에 대한 변형 또는 구조부재간의 상대변위에 의한 변위지배적인 거동에 따른 배관계통과 주요 배관요소의 지진거동을 분석하였다. 배관계통의 변형각은 기존의 센서를 이용하여 측정하기가 어려우므로 이미지측정시스템을 적용하였다.
Abstract
In this study, a steel frame that realized the second floor of a structure was fabricated in referring to NFPA 13. In addition, a riser pipe system with groove joints was installed, and a seismic simulation test was performed using static cyclic loading. Cyclic loading tests on the maximum allowable side sway of seismic design standards for buildings in Korea were conducted using actuators to analyze the seismic behavior of the riser pipe system and major piping elements due to the deformation of the steel frame structure or the displacement-dominant behavior caused by the relative displacement between the structural members in the event of a seismic load. Moreover, the deformation angle of the riser pipe system was measured using an image measurement system because it is difficult to measure using the conventional sensors.
