چکیده
|
Large capacity cylindrical tanks are used to store a variety of liquids. their satisfactoryperformance during earthquake is crucial for modern facilities. in present paper, the behavior of cylindricalconcrete tanks under harmonic excitation is studied using the finite element method. liquid sloshing, liquidviscosity and wall flexibility are considered and additionally excitation frequency, liquid level and tankgeometry is investigated. the results show a value for wall thickness to tank diameter ratio which mav be usedas a guide in the consideration of wall flexibility effects.
