Abstract

In order to study the characteristics of fiber reinforced bearing, the steel plates of laminated rubber bearing were replaced with fibers which have same effects of steel plates. The comparison of vertical test and horizontal test of laminated rubber bearing and fiber reinforced bearing shows that the effective damping of fiber reinforced bearing is higher than laminated rubber bearing. This result implies the high energy dissipation ability of fiber reinforced bearing under earthquake excitation. These fiber reinforced bearing can be applied to the low-coast building.

면진베어링으로 기존에 사용되고 있는 철판보강 면진베어링에서 철판을 섬유로 대체하여 섬유보강 면진베어링을 설계 및 제작하였다. 섬유면진보강베어링의 특성을 파악하기 위해서 철판보강 면진베어링과 섬유보강 면진베어링에 대해 수평실험과 압축실험을 수행하였다. 시험결과 섬유보강 면진베어링의 유효 감쇠는 천연고무 면진베어링에 비해서 높았다. 이 결과는 지진하중하에서 섬유보강 면진베어링은 에너지 분산능력이 뛰어나다는 것을 의미한다. 이 연구결과로 인해 섬유보강 면진베어링이 저가건물에 널리 사용될 수 있을 것으로 기대된다.
