| Abstract |
Orifices are installed on the horizontal tube of a tuned liquid column damper in order to increase the coefficient of head loss of the damper. Because such orifices control the flow of the horizontal tube, there is a variation in the level of water in the vertical tube. In general, only one orifice is installed in the middle for controlling the flow of the horizontal tube. In this study, examined the damping characteristic of a tuned liquid column damper according to porosity, the number of orifices installed and natural frequency. Amplitude response was lower when orifices were not installed than when they were, and the lower amplitude response increased the head loss coefficient. Compared to when only one installed, when two orifices were installed amplitude response decreased by up to 7%. |
