Wind Response of Circular Towers and Response Reduction Method by Tuned Mass Dampers and Tuned Liquid Dampers

Abstract

High-rise circular tower is considered as slender building which is subject to a high response under the wind load. The vibration may disturb the harmony of resident and cause deficiency to non-structural component. The vibration control device known as “Dampers” has been developed to control structural response under dynamics load by give an equivalent damping to overall structural system. It has an advantage over the conventional design such as reduce a wasteful of structural material and other function design. This research focus on the approximated formula to design an optimum parameter and the formula to estimate an equivalent damping of structural system obtained from 2 type of mass dampers, namely Tune mass Dampers (TMD) and Tuned Liquid Damper (TLD). Experiment the structural design with the circular watchtower to study the profit of mass dampers compared with conventional design. The result show that mass dampers significantly reduce the amount of structural work.
