Reinforced concrete elevated reservoirs with frame support are structures commonly used in Peru for the storage and supply of water to the population, so their operability should continue after a severe earthquake, since they are essential structures that provide access to this essential input that is essential for the well-being of the population. The 2007 Pisco earthquake revealed the vulnerability of these structures, where failures have been shown in beams and beam-column joints, affecting the frame support structure of the elevated reservoirs, rendering them inoperative due to the great risk they represent. The main subject of this research is the non-linear seismic response of reinforced concrete elevated reservoirs with frame support for different storage capacities, located on the coast and highlands of Peru, for this purpose the E.030 technical standard has been used (2018) and international codes to establish the preliminary design parameters, including ACI 350.3¬20 and IS 1893 (part 2): 2014. To determine the nonlinear seismic response, the international codes ASCE/SEI 7-22, FEMA 356, FEMA 440, FEMA 450 and ATC-19 (1995) were used. Thus, 26 models of reinforced concrete elevated reservoirs with frame support have been proposed for the seismic zones Z3 and Z4, to which the Pushover analysis was carried out to determine the maximum capacity. Five seismic records of severe earthquakes that occurred in Peru have been considered, scaled for seismic demand consistent with current regulations, which were needed for nonlinear dynamic analysis. In addition, the methodology established in the ATC-19 code (1995) has been used to determine the seismic response modification factor, R, and factors such as displacement ductility, overstrength, redundancy, among other parameters, have been evaluated. On the other hand, the design of El Carmelo reservoir has been verified with current regulations of Peru and other international codes, to determine the level of performance of the structure for different levels of seismic demand and thus understand its behavior, since which has a structure commonly used in the country.
