초록

본 연구에서는 공공건물에 보강이 가능하도록 건물 외부에 록킹 월을 설치하고 이를 본 구조에 강재댐퍼로 연결하는 외부 보강 내진공법에 대한 기초 연구를 시행하였다. 2개의 실험체를 제작하였으며, 댐퍼 비보강 실험체는 기존 결과를 활용하였다. 포락선, 강도, 강성저하 및 에너지 소산능력을 평가한 결과, 플레이트 댐퍼를 외부 보강한 RW_P 실험체의 강도 증진이 우수한 것으로 평가되었다. 또한 S형 댐퍼를 외부 부착한 RW_S 실험체는 최대하중 이후에 완만한 포락곡선을 보여 댐퍼가 하중을 적절히 소산하는 것을 확인할 수 있었다.

In this study, a basic study was carried out on the external strengthening method of public buildings. A steel damper is installed outside the specimen with a rocking wall and connected to the frame. Two specimens were fabricated, and the non-reinforced specimens utilized the existing results. As a result of evaluating the envelope curve, strength, stiffness and energy dissipation capacity, it was evaluated that the strength enhancement of the RW_P specimen externally reinforced plate damper was evaluated to be excellent. In addition, RW_S specimens with external S type damper shows a gentle envelop curve after maximum load, and it can be confirmed that the damper properly dissipates the seismic energy.
