Advances and Trends in Seismic Design of Cylindrical Liquid Storage Tanks

Abstract

The author presented a review of seismic studies of cylindrical liquid storage tanks in ref. 1 in 1983. Six years have passed since then. During this period, many more studies have been performed, and great progress has been made in tackling problems that were unsolved at that time. Particularly numerous following the Nihonkai Chubu Earthquake of 1983 have been studies on liquid sloshing and long-period ground motions. Studies on the behavior of tanks and the coupled vibrations between soil and tanks have focused on the problem of when the bottom plates of tanks lift off from the foundation. The development of the fast breeder reactor (FBR) has necessitated studies on the seismic safety assessment of coaxial liquid contalners. In this connection, the advances and rends in seismic studies of liquid storage tanks performed after the early 1980s will bb surveyed. Remarkable studies conducted even before the 1980s will also be metioned.
