ABSTRACT

Elevated reservoirs are used to store a variety of liquids. During earthquake activity the liquid exerts impulsive and convective pressures (sloshing) on the walls and bottom of tank. This paper provides theoretical background for analytical calculating of elevated tanks during an earthquake and deals with comparing of simplified seismic design procedures for elevated tanks, and the applicability for subsoil classes. The analysis has been carried out considering four different subsoil classes A, B, C, D, given EC8. The design by simplified seismic procedures given EC8 and Housner model was compared.
