Journal Article 2018 12 24 The seismic responses of the water-filled prestressed concrete cylindrical tanks have been investigated under earthquake inputs. A series of dynamic-explicit analyses have been performed to study water sloshing phenomena effects on the prestressed concrete tank behavior using ABAQUS software. A shaking table test program has been conducted to validate the numerical analysis. Additionally, the numerical analysis capability to simulate the sloshing waves has been verified using mathematical results. Several numerical models have been prepared with different radius to water height ratios (R/H). The recorded El-Centro, Tabas and Bam accelerations have been employed as the seismic loading in the numerical models. The comparison between the experimental and theoretical results with numerical outcomes demonstrates a reasonable agreement. The seismic excitation effect on the prestressed tendons loss is negligible in the investigated numerical models.
