Abstract
Cylindrical steel tanks are important components of many industrial plants such as oil refineries and chemical plants. Usually failure of
cylindrical tanks leads to serious consequences. During the past earthquakes such as 1964 Alaska and 1999 Turkey seismic performance of
cylindrical tanks revealed that tanks are seismically vulnerable. Therefore, evaluation of seismic performance of these structures is an
important task in seismic prone areas. During an earthquake, a sloshing motion may occur in upper parts of the liquid. In storage tanks
during earthquake if fluid wave height in tank increases, the fluid wave may damage the roof or some parts of roof holders. The tanks
should resist against unfavourable impacts such as earthquakes. In this paper, 5 tanks with different H/D ratios in an oil refinery complex in
Iran were studied using static and dynamical analysis (linear and non-linear). Spectrum and time history linear and non-linear analysis was
completed in order to find the fluid wave height and also ratio of wave height to the tank diameter.
