Time History Analysis of Structure having Water Tank at the Top of Building Acting as a Tuned Liquid Damper

Abstract

An earthquake is a natural phenomenon occurring worldwide. Depending upon the intensity, it may cause damage to life and property. Continuous research is carried out to find the different methods that can provide a solution to minimize this damage. The idea of seismic response control of the structures by using over head water tank as a passive TMD’s is considered for the study. The main objective of this study is to find out response reduction of the structure subjected to different earthquake data. Analysis is carries out for six storied building with and without water tank for different water tank positions and different water levels such as empty water tank, half filled water tank and full filled water tank. Three types of earthquake data are considered for the study namely, El-Centro, Kobe and loma prieta. For performing Time history analysis SAP 2000 software is used in this study. Results show that tuning the parameters of water tank, it can be used as passive TMD to reduce the seismic response.
