earthquake vibration control of structures using tuned liquid dampers: experimental studies
earlier studies have shown conclusively that a tuned liquid damper (tld) is effective for controlling vibrations in structures subjected to narrow-banded wind excitations. a recent numerical study has shown that if the design parameters of a tld are properly set, this device could also be very effective for controlling structural vibration to broad-banded earthquake excitations. here the result...
متن کاملOPTIMIZED TUNED LIQUID COLUMN DAMPERS FOR EARTHQUAKE OSCILLATIONS OF HIGH-RISE STRUCTURES INCLUDING SOIL EFFECTS
This paper investigates the optimized parameters for the tuned liquid column dampers to decrease the earthquake vibrations of high-rise buildings. Considering soil effects, the soilstructure interaction (SSI) is involved in this model. The Tuned Liquid Column Damper (TLCD) is also utilized on the roof of the building. Since the TLCD is a nonlinear device, the time domain analysis based on nonli...
متن کاملMeasurement of the resonance frequency of single bubbles using a laser Doppler vibrometer.
The behavior of bubbles confined in tubes and channels is important in medical and industrial applications. In these small spaces, traditional means of experimentally observing bubble dynamics are often impossible or significantly perturb the system. A laser Doppler vibrometer (LDV) requires a narrow (<1 mm diameter) line-of-sight access for the beam and illumination of the bubble does not pert...

متن کاملDynamic response mitigation of floating wind turbine platforms using tuned liquid column dampers.
In this paper, we experimentally study and compare the effects of three combinations of multiple tuned liquid column dampers (MTLCDs) on the dynamic performance of a model floating tension-leg platform (TLP) structure in a wave basin. The structural stability and safety of the floating structure during operation and maintenance is of concern for the performance of a renewable energy device that...
