The paper analyzes the effectiveness of tuned liquid damper in controlling the vibration of high rise building. The new contribution is considering the fluid-structure interaction of a water tank as a Tuned Liquid Dampers (TLD).


Currently, buildings are being built higher and higher, which requires TLDs to be larger as well. Therefore, the fluid pressure acting on the tank wall is more significant. In previous studies of liquid sloshing in TLDs, researchers simply ignored the effect of liquid pressure acting on the tank walls by making the assumption that the tanks are rigid. Currently, the failure of a tank because of FSI occurs regularly, so this phenomenon cannot be ignored when designing the tanks in general and TLDs in particular.


To investigate the thickness of the tank wall affect to the TLD mechanism.


Numerical method was used for this research.


A TLD could be easy to design; however one could not bypass the fluid-structure interaction by assuming the tank wall is rigid.


This kind of damper is very good to mitigate the dynamic response of structrure.
