Abstract

The interaction of fluid-shell surface of tanks built on roof of buildings and the resulting damage during an earthquake is of great importance. The existence of containers on buildings in large cities with high earthquake risk has caused many critical problems during past earthquakes. In addition to financial losses, it might induce uncontrolled fire, water cut and local or global failure of the structure. Moreover, the influence of this interaction on structure dynamic behavior can cause structural failures. Therefore, it is important to become assured of the behavior of structures with such tanks during an earthquake. The seismic response of a structure depends on its dynamic characteristics, including its frequency, mode shapes and damping effect. The first step in analyzing the structural response to an earthquake is the calculation of frequencies and trembling periods. Dynamic characteristics of a structure are highly influenced by presence of fluid in the vicinity of the structure. In this study, the dynamic interaction of water containers built on roof of structures, is investigated during an earthquake by means of nonlinear software based on Finite Element Method. In this paper, the compound system of structure, tank and water has been examined under seismic excitements simultaneously. The analytical method used is the Finite Element Method, and calculations have been -done with the aid of ANSYS software. The tank shell and its water have been modeled as a composite system and the interaction of container and water have been examined. This seismic control system with its limited potential capability as a tuned liquid damper (TLD) has been employed and investigated for 5 -story building structure, subjected to two various earthquakes. The significant influence of earthquake frequencies and type of stations used for seismic accelerometers on structural trembling and effect of such tanks on structures are among the main conclusions drawn from this study. The results gained from the present study can be helpful in investigating the tank's support conditions and its installation. It has been found that, in structures with few stores (or lower period) the importance of accelerometer type is more. Therefore, for low-story buildings, definite statement about structural seismic behaviors is quite difficult.Conversely, for tall buildings such statement can be done with more certainty. Based on the numerical results obtained in this paper, frequency content and other earthquake characteristics highly affect the role of water tanks on the seismic performance of lower rise buildings.
