Seismic analysis of cylindrical liquid storage tanks

Abstract This paper summarizes the results of a comprehensive analytical investigation concerning the seismic analysis of ground supported, circular cylindrical liquid storage tanks subject to a horizontal component of earthquake ground motion. A procedure to evaluate the dynamic seismic response of a wide range of cylindrical liquid storage tanks is developed. The procedure, which is applicable to tanks both completely full and partially full with liquid, has been incorporated into a BASIC computer program. Several numerical examples are presented which illustrate application of the procedure and verify its accuracy.
