Analysis of the peak vertical displacement of liquid surface due to sloshing

Abstract

When a tank containing liquid vibrates, the liquid exerts hydrodynamic effects on the solid domain of a tank. In the case of roof tanks, a large sloshing wave will impact the wall or roof of the tanks and may cause extensive damage or failure of the tanks. This paper provides the theoretical background of simplified seismic analysis of liquid storage cylindrical ground -supported tanks, and it documents the seismic effect of input motions characteristics on fluid sloshing behaviour.
