A Comparative Study of the Seismic Analysis of Rectangular Tanks According to Different Codes

Abstract eng:
As known from very upsetting experiences, liquid storage tanks were collapsed or heavily damaged during the earthquakes all over the word. Damage or collapse of the tanks causes some unwanted events such as shortage of drinking and utilizing water, uncontrolled fires and spillage of dangerous fluids. Due to this reason numerous studies done for dynamic behavior of fluid containers; most of them are concerned with cylindrical tanks. But very few studies on the seismic response of rectangular containers exist. Therefore this study is to be mostly about rectangular tanks. Comparative seismic analyses are carried out for a rectangular tank considering requirements and expressions given in seismic codes prepared for USA, European Community and New Zealand. Turkish seismic code is also discussed. Hydrodynamics pressures, sloshing displacements, base shears, lateral displacements, bending and overturning moments are determined for considered codes and specifications. Finally, results obtained this study are evaluated and some conclusions related to the encountered differences and similarities for seismic analysis and design of rectangular tanks.
