Abstract

As tall buildings have increased in Korea, various dampers have been applied. In order to minimize the space, cost and construction process, the new hybrid friction damper which can be installed at a coupled beam was developed. This damper, which is composed of two one-nodal rotary frictional components and a slotted bolted frictional component, is able to operate at various displacements of building. In this study, dependency tests were carried out to evaluate on the structural performance of one-nodal rotary frictional component. Test results show that one-nodal rotary frictional component does not depend on a displacement, a frequency and a long term loading. However friction coefficient is reducing as a clamping force is increasing.

국내 고층건물이 증가함에 따라 다양한 형상의 제진댐퍼가 적용되고 있다. 설치공간, 비용 및 시공과정을 최소화하기 위해서 연결보에 설치가능한 새로운 혼합형 마찰댐퍼를 개발하였다. 혼합형 마찰댐퍼는 두 개의 1절점 회전형 마찰요소와 슬롯형 마찰요소로 구성되어, 다양한 건물변위에서 작동할 수 있다. 본 연구에서는 혼합형 마찰댐퍼를 구성하는 1절점 회전형 마찰요소의 구조성능을 평가하기 위하여 의존성 실험을 수행하였다. 실험결과 진폭, 주파수, 장기반복가력에 대해서 의존성을 나타내지 않았으나, 축력이 증가할수록 마찰계수는 감소하는 경향을 나타내었다.
