This research seeks to evaluate the soil structure interaction (SSI) in elevated water tanks of three different capacities, founded on different types of soil, all located in the most seismic hazard zone in Peru. Twenty-seven models were evaluated, all with different structural adjustments, including variations in the capacity, height, and diameter of the foundation slab, which are founded on four types of soil, according to the Peruvian Code for Earthquake Resistant Design E.030-16. We are going to analyze the seismic load influence through a spectral dynamic analysis, according to the Peruvian Code E.030-16, and the ACI 350.3-06 code for elevated tanks. For the sizing of the elevated tanks, the Otto Intze criterion, the static stress analysis, the ACI 350.3-06 and the ACI 307-48 code were applied. These elevated water tanks were modeled in the SAP2000 software, with 216 simulations. The Housner model (1963) was applied for the Fluid Structure Interaction, and for the Soil-Structure Interaction (SSI), we applied the model recommended by the FEMA P-750 code. To analyze the results of interest, such as internal forces in the shaft, base shear, rocking moment, displacements and periods, we applied the Shapiro Wilk normality test for the percentage variation that is generated when we evaluate the SSI, in order to determinate variations intervals with a probability of 95%. Also, we applied the Chi-Square test of independence to determinate, quantitatively, if the results are influenced by the SSI. We concluded, from the independence test that, for a significance level of 15%, the SSI influences the reduction of the basal shear force and the rocking moment. Likewise, for a significance of 5%, the SSI influences the reduction of the internal shaft forces.
