| Abstract |
In this study, in order to investigate the effectiveness of tuned liquid damper (TLD) for the seismic performance enhancement of the existing reinforced concrete (RC) apartment structure which was not seismically designed, shaking table test was conducted for the small scale five story RC structure with TLD. TLD model was constructed to have the frequency tuned to the first modal frequency of the structure, 2% mass ratio of the first modal mass, and 0.08 liquid depth ratio.
White noise and harmonic load tests were performed using the shaking table, and the displacement and absolute acceleration of each floor were measured.
Test results indicate that more than 30% responses reduction can be achieved using TLD for RC structure under white noise and harmonic load. |
