초록
최근 국내․외적으로 대형 건설구조물이 증가함에 따라 여러 유해진동에 대한 구조물의 안전성 확보에 관한 관심이 높아지고 있다. 특히 돌발적인 지진 및 돌풍 등의 발생 규모와 빈도가 점차 가중되는 실정에서 건설구조물의 진동제어에 관한 지속적인 연구가 요구된다. 최근에는 MR 댐퍼를 활용한 준능동 제어방법이 기존 수동 제어 및 능동 제어방법의 새로운 대안으로 부각되었다. 본 논문에서는 건설구조물의 준능동 제어를 위해 응용될 수 있는 전단형 MR 댐퍼의 설계와 실험적 성능평가에 관한 연구를 수행한다. 연구의 결과로써, 본 논문에서 설계․제작된 전단형 MR 댐퍼가 준능동 제어장치로써 유효하였고, 더불어 전단형 MR 댐퍼의 초기 설계 및 성능평가에 관한 실험적 자료를 제공하였다.
Abstract
The concern for securing the structure safety is growing in recent years as the number of large-scale construction structures is increasing at home and abroad. Especially in current circumstances where unexpected earthquakes and gusts of wind occur on larger scales and more frequently, continuous researches on vibration control in construction structures are required. Recently, a semi-active controlling method using MR dampers has come to the fore as a new alternative to the existing passive control and active control mechanisms. In this thesis, a study is carried out on the design and the experimental performance evaluation of shear-type MR dampers which can be applied in the semi-active control of construction structures. As a result of the study, the shear-type MR damper that was designed and produced in this thesis has been proved to be appropriate as a semi-active controlling device, and the experimental data on the initial design and performance evaluation of shear-type MR dampers has been provided additionally.
