Elevated reservoirs are structures that are used to store and distribute drinking water to a population, and are part of a vital lifeline system that after the occurrence of an earthquake should not be interrupted, and much more in those cases of emergency.The last major earthquake that occurred in the country on August 15, 2007 in Ica, has revealed the vulnerability of this type of structure, in which many high water storage towers with cylindrical shaft type support have been affected. The peruvian earthquake design code NTE E-030 establishes parameters for the design of buildings in the country, not indicating any value for the reduction factor of the seismic response (R) for structures of elevated reservoirs, due to the very limited research carried out in the country, which has forced the designers of this type of structures to consider US standards (ACI, ASCE, FEMA, ATC); using the Intze principle for its pre-dimensioning. This research work, high reservoirs have been analyzed for a seismic demand with parameters of height of more common support structure and storage capacity for populations of 1250 to 15000 inhabitants approximately, located in the zone of coast and mountain range of the country and with firm soil condition. Pushover analyses have been used to determine the maximum static capacity, and the nonlinear time history analysis with 05 seismic records of some of the more severe earthquakes occurred in the country, which have been scaled up to match the design response spectrum of the standard for R = 1, determining the maximum dynamic capacity for this level of seismic demand. The ATC-19 (1995) methodology was applied for the determination of the R factor, reaching parameters such as: displacement ductility, maximum distortion, overresistance, hysteretic behavior among others of the high reservoir structures. It was determined that the value of the R factor for high reservoirs varies between 1.82 to 2.48 and that the high reservoirs in the country present a satisfactory behavior not presenting significant damage before the occurrence of a severe earthquake.
