초록

기존의 내진 설계 방법은 소성 변형으로 인해 부재를 재사용할 수 없다는 한계가 있다. 이는 최적의 내진 설계 방법이 아닌 것으로 판단된다. 따라서 본 연구에서는 부재 수준에서 재사용할 수 있는 에너지 소산 장치를 제시하고자 한다. 에너지 소산장치는 보-기둥 접합부에 설치하여 실제 규모의 실험을 수행하였다. 실험 결과 보와 기둥의 부재별 변형률 및 변형을 검토한 결과 모두 탄성 거동한 것을 확인하였다. 회전 능력과 강도는 국내 설계기준에서 제시한 수준 이상의 내진 성능을 확보한 것을 확인하였다. 또한 실험체 설계를 위하여 제시한 예측식은 최대 10 %의 오차가 발생한 것으로 나타났다. 따라서 대상 장치를 적용할 경우 설계 의도에 따라 주요 부재를 재사용할 수 있을 것으로 사료된다.

Abstract

Existing seismic design methods have limitations in that members cannot be reused due to plastic deformation. This is judged not to be an optimal seismic design method. Therefore, this study aims to present an energy dissipation device that can be re-used at the component level. An energy dissipation device was installed at the end of the beam of the unit connection to conduct a real-scale experiment. As a result of the experiment, the elastic behavior of the column and beam members was confirmed as a result of reviewing the strain and deformation by element. The rotational capacity and strength showed seismic performance above the level suggested by the domestic code. In addition, the prediction equation presented for the design of the test specimen showed an error of up to 10 %. Therefore, it is thought that the main members can be reused according to the design intention when applying the target device.
