Reduced Effect of Vibration by Using Different Liquids in Tuned Liquid Column Damper

In present era, the construction of high rise building is increasing day by day. These structures are more flexible and having low damping value. Due to low damping value the failure possibilities increases and also from the point of serviceability. The vibration induced in such type of structure due to wind or earthquake causes large trembling and due to this large deflection. Today various techniques are available to minimize the effect of vibration induced in the structure due to earthquake. Tuned liquid column damper is one of the techniques to minimize the effect of vibration induced in high rise building. A tuned liquid column damper is a special type of damping technique which prevents the vibrations acting on the high rise building due to earthquake by providing a U-tube at top of the building. This technique is based on inertia of U-tube liquid column. In this study we made a model of a structure attached with tuned liquid column damper. Initially we check the displacement of structure without damper at different frequency. Plot a graph between displacement and frequency. We place a tuned liquid column damper on the top of the structure model and filled it with water. Again we check the displacement of the structure at different frequency and plot the graph. This time the water is replaced with hair oil and the displacement is checked at different frequency and plot a graph between displacement and frequency. Lastly, the hair oil is replaced with Mobil oil and check the displacement at different frequency. Plot another graph between displacement and frequency. Compare all the above graphs and get the result. The result confirmed that the use of different oil minimizes the effect of vibration on the structure due to earthquake.
