    The present research work performs an analysis of the structural behavior of a six-story building in metallic structure with the use of elastomeric seismic base isolators, which allows us to perform a comparative analysis of the structural behavior through the vibration periods that directly influence the floor drifts as displacements, of an isolated and non-isolated structure. It was performed prior to the analysis of several structural probabilities, seeking that the structure complies with the minimum seismic resistant requirements suggested by the Ecuadorian Construction Standard "NEC 15", as well as the Complementary Technical Standards for Earthquake Design, "NTC-DS-2017", the Chilean Standard "NCH-2745", the American Institute of Steel Constructions "AISC 341- 16" code and the American Society of Civil Engineers "ASCE 7-16, ASCE 41-13, which, by their design characteristics, provide seismic resistant safety. The mathematical model for the calculation was made based on the characteristics of the architectural and structural drawings, making a stabilized structure obtaining floor drifts and displacements in accordance with the requirements of the NEC-15 recommendations, consequently, the seismic isolation was made through the pre-dimensioning and design of the elastomeric base isolators with lead core type LRB. Subsequently, the scaled accelerograms were entered into the structural model of the software, in order to establish a nonlinear dynamic time-history analysis and to obtain a real analysis of the structure, a nonlinear static analysis was performed. With the data entered into the software, results were obtained for a building without isolation, including: vibration periods, displacements, floor drifts, basal shear, accelerations, overvoltage of the structure and energy balances; likewise, the basic seismic isolation was implemented in which the expected results were obtained, in order to perform a comparative analysis of a structure with and without isolation.
