본 논문은 현재 국내에서 연구되고 있는 동조액체댐퍼중에서 적은 외부 가진에도 효과가 있는 직사각형과 원형의 낮은수조(shallow water)을 이용하여 4개의 동일한 고유진동수 변화에 따른 TLD수조의 형태별 가진진폭별변화에 따른 밑변전단력, 파고, 감쇠율을 분석을 실시하고자 한다. |

The present study examined the characteristics of rectangular and circular tuned liquid dampers (TLDs), which are used to control wind-induced vibration in tall buildings, according to natural frequency. For this, we conducted shaking table experiments for four natural frequencies (0.44, 0.55, 0.64 and 0.73Hz). The tuning characteristic of the TLD water tanks was better in circular water tanks than in rectangular water tanks. The damping ratio based on the energy dissipation capacity was affected by the excitation amplitude. At low excitation (below amplitude 5mm) and low natural frequency (0.44Hz), circular water tanks were more advantageous than rectangular water tanks. However, at high excitation (over amplitude 5mm) and high natural frequency (over 0.55Hz), rectangular water tanks were better than circular water tanks. |
