Abstract

One way that can be used to increase the resistance of structures to dynamic loads is to add damping to the structure. Tuned Liquid Damper is a rigid liquid filled tank and is positioned on one of the floors of a building with the aim of reducing the dynamic response of the structure to external excitation. Using the formula of den hartog optimum TMD modified with formula for frequency of rectangular Tuned Liquid Damper, several set of table and graph is made to select the optimal dimension of TLD. Using TLD with this dimesion an experimental nodel is created and the result is compared with simulation model. The results from this study shows that displacement matlab model has 7.4% at first floor and 8.1% at second floor. Also the result for displacement experimental has 18.75% at first floor and 13.63% at second floor. Therefore it can be concluded between these two methods TLD have significant impact in decreasement of structure response.
