Dynamic Analysis of Water Tanks with Interaction Between Fluid and Structure

Abstract eng:
Due to growing population and expansion of cities, the number of elevated water tanks supplying the demand urban water system is on the rise. As it has been mentioned in the Iranian code of practice for Earthquake /2800 because of the importance of sanitation and hygiene water tanks have been considered as important structures during the unexpected events such as earthquake. There is a great expectation not to see any phase out for their serviceability after the earthquake. Because of the presence of fluid with different behavioral properties of structures containing it and the most part of mass of tanks are located in a considerable distance from its foundation, the behavior of these types of structures in compare with conventional structures are more complicated. In this research, cylindrical concrete water tanks, which have a central shaft, have been evaluated with considering the effect of the structure’s interaction with water through precise implementation of boundary conditions on the interface between fluid and structure. Also considering the level of water in the tank and their behavior under recorded acceleration of different earthquakes using finite element method. The results were then compared with suggested methods by Iranian code /2800, which the results show a relatively considerable difference between mentioned methods.
