Abstract

Earthquakes have caused enormous tragedies for human beings all the time, especially in this century. A more recent tragic earthquake that has already taken four more thousand of lives is still a living tragedy nowadays in the border area between Turkey and Sialia. How to avoid this kind of tragedy becomes an important mission to almost everybody who ever works in the related field, yet the challenge is too difficult to overcome. Many approaches have been tried such as to understand the vibration source and try to predict the occurring cycle or to detect the trembling signal and try to warn the surrounding area as early as possible. All of those methods are important but not easy to approach, especially for an area that is remote, underdeveloped but populated. A more effective but cheap approach must be provided as in this research, where a typical TLCD (Tuned Liquid Column Damper) device combined with a TMD (Tuned Mass Damper) device was installed in a structure to mitigate the earthquake-induced vibrations. It is found from the results of the study that for vibrations with either a long period or short period the amplitudes of the vibration can be eased by 70% in terms of the transfer function of the displacement. According to the results in this study the method is also applicable to large and heavy buildings and structures.
