This paper aims at the analysis and behavior study of cylindrical on-ground oil reservoirs using the endurance time (ET) method with acceleration functions that are compatible with real earthquake accelerograms, and comparing the results with those obtained from acceleration functions that are compatible with standard code 2800 design spectra. An anchored cylindrical reservoir has been studied using a finite element\ procedure\ that\ includes\ the\ fluid\ elements\ \ of\ \ the\ \ content\ \ to\ \ model\ \ structure-fluid interaction. A linear analysis using static, modal, response spectrum and time-history procedures has been conducted
and the results have been compared with those in literature. After model verification, time-history analyses were conducted by considering a set of seven earthquake records; three code 2800 compliant ET acceleration functions and three earthquake compliant ET acceleration functions and the results were compared. The results show that both ET acceleration function sets predict stress and deformations with reasonable accuracy, but for reliable prediction of the maximum height of sloshing, real earthquake compatible acceleration functions have to be used.
