철근콘크리트 건물의 내진보강을 위한 토글-회전형 마찰댐퍼의 실험적 연구

초록

The purpose of this study is to investigate seismic capacit ies of the Toggle-Rotational Friction Damper for strengthening reinforced concrete buildings, based on a laboratory test. In this study, a shape of the Toggle-Rotational Friction Damper was dev eloped and three specimens were also fabricated. Experiments wer e carried out using the static loading condition. The result indicated that the seismic strengthening effect of the proposed damper in terms of strength and ductility demands was comparatively good compared to the control specimen.
