| Abstract: | A pendulous water tank is used in the design of a building by fixing the tank on its top. The vibration of water in the tank and the energy exhausted by the swaying of the tank can reduce the seismic responses of the building. An analytical model of the construction with pendulous water tanks is proposed. Based on the dynamic response of the construction, the effectiveness of the pendulous water tank in reducing seismic responses of the construction is discussed. Finally, time-history results under three seismic waves are given, and the control of the responses in both displacement and acceleration of the structure is farily good. |
