Large capacity cylindrical tanks are used to store a variety of liquids. Their Satisfactory performance during earthquake is crucial for modern facilities. In present paper, the behavior of cylindrical concrete tanks under harmonic excitation is studied using the finite element method. Liquid sloshing, liquid viscosity and wall flexibility are considered and additionally excitation frequency, liquid level and tank geometry is investigated. The results show a value for wall thickness to tank diameter ratio which mav be used as a guide in the consideration of wall flexibility effects.
