회전형 마찰댐퍼 성능에 대한 실험적 연구

The hybrid damper system has been required since the slenderness ratio is increasing recently. To minimize an installment space and construction process, the proposed hybrid damper installs at a lintel beam. It is composed of two rotational friction dampers and a multi-level slotted bolted connection friction damper. They are connected at two pin joints and slotted bolted connection friction damper has a slotted hole. So it can activate as the hybrid friction damper adding a slotted bolted friction damper under a earthquake load while behave as only a rotation friction damper under wind load. In this paper, the structural performance of a rotational friction component of the proposed hybrid damper has been evaluated through dependency tests.
