A Survey on Hydrodynamic Pressure in Seismic Analysis and Design of Liquid-Containing Structures

A Survey on Hydrodynamic Pressure in Seismic Analysis and Design of Liquid-Containing Structures

Water supply systems consist of numerous raw and treated water-containing structures. Steel cylindrical storage tanks are even more widely employed in oil terminals, refineries, and chemical plants. Such liquid-containing structures may be exposed to high seismic risk in earthquake-prone areas and are very vulnerable if not well designed. The damage of such structures is associated with the response of the liquid and the induced hydrodynamic load upon the structures. In this study, the investigations by Housner and Veletsos on this topic have been explained. The hydrodynamic pressure specified in various codes and guidelines for the seismic analysis and design of liquid-containing structures has also been introduced.
