Abstract

At the present time, an earthquake is one of the problems for the high-rise building structures. This paper presents an analysis and an examination of Tuned Mass Damper (TMD) in order to study the possibility of using the water tank as the TMD. The finite element method is used as a tool in structural analysis. A study of four, eight and twelve story-three dimensional reinforced concrete buildings with water tank placing on the roof is evaluated. The total mass of the whole system including water tank, water, beams,columns and slabs are considered. The behavior of the tank subjected to both El-Centro 1940 and Chichi 1999earthquake data are studied under the condition of full water within a tank. The lateral displacements of the building without water tank are compared with the building with full water tank. In conclusion, use of the water tank is found to be able to reduce vibrations from earthquake in some cases.
