Abstract

The ability of large, liquid-containing structures to resist earthquakes without damage is a subject of considerable interest not only to the engineering profession but also to the community at large. This is because these structures often constitute an essential part of a community's lifeline and must therefore be maintained viable during emergencies. Also, in some applications the stored contents may be hazardous in which case their accidental release must be prevented. The behavior of structures subjected to earthquake-induced fluid pressures was first studied in the early 30's by Westergaard and others. In 1949 and 1951 Jacobsen analyzed a rigid cylindrical liquid-containing tank and a cylindrical pier surrounded by liquid, subjected to horizontal accelerations. Subsequently, Housner simplified the method of analysis and introduced the concept of the two components of dynamic pres
