초록

본 연구에서는 하나의 제어장치로 서로 직교하는 2방향의 건물응답을 동시에 제어할 수 있는 동조액체질량감쇠기(Tuned Liquid Mass Damper; TLMD)를 제안하고 제어성능을 실험적으로 검증하였다. 본 연구에서 제안된 TLMD는 한 방향으로는 동조액체기둥감쇠기(Tuned Liquid Column Damper; TLCD) 내부에 채워진 액체의 운동에너지를 이용하여 구조물의 응답을 제어하게 된다. 그리고, 다른 한 방향 즉 TLCD의 직각 방향으로는 LM guide(linear motion guide) 위에 놓인 TLCD 수조와 내부의 액체의 질량을 이용하여 동조질량감쇠기(Tuned Mass Damper; TMD)로 거동하게 함으로써 구조물의 응답을 감소시킨다. 이와 같은 TLMD의 양방향 독립거동 특성을 증명하기 위해 실물크기의 구조물에 설치하여 강제진동실험을 수행하였다. 실험결과, 양방향 모두 대상 구조물의 응답을 감소시키는 것을 확인하여 제안된 TLMD의 효용성을 검증하였다.

In this paper, a tuned liquid mass damper(TLMD) was proposed and experimentally investigated on its control performance, which can control bi-axial responses of building structures by using only one device. The proposed TLMD controls the structural response in a specific one direction by using a liquid sloshing of TLCD. Also, the TLMD reduces the response of structures in the other orthogonal direction by behaving as a TMD that uses mass of the container itself and liquid within container of TLCD installed on linear motion guides. Force-vibration tests on a real-sized structure installed with the TLMD were performed to verify its independent behavior in two orthogonal directions. Test results showed that the responses of a structure were considerably reduced by using the proposed TLMD and its usefulness for structural control in two orthogonal directions.
