    Ecuador is located in the Ring of Fire, so it is subject to stochastic phenomena such as earthquakes, since buildings must be governed according to the current NEC 15 standard to ensure that the design meets earthquake resistance criteria. The purpose of this research work is to determine the seismic performance of the building under study. A qualitative analysis was carried out using the NEC 15 standard, in which the parameters were evaluated according to the characteristics of the structure, obtaining a score of 2.0, demonstrating that it has a medium degree of vulnerability. In the quantitative section, the linear and nonlinear static Pushover analysis of the structure was carried out using engineering software. In the linear analysis, it was determined that the structure in current conditions presents torsion, and that elements such as beams and columns are not designed to withstand the demands. In addition, through non-linear analysis, the capacity curve of the structure was calculated together with the performance levels and it was determined that the construction does not meet the seismic performance objectives according to VISION 2000. Once the evaluation of the structure was completed, three more floors were designed, according to the specifications of the calculation report, and with the requests of these, the structure was reinforced, both locally in the elements such as columns and beams using criteria from the ASCE 41-13 standard, in which the concrete screed method was used for the columns and the steel casing method for the beams, and globally with the implementation of shear walls to control torsion and comply with the vibration period of the structure. Finally, with the implementation of the reinforcement and the addition of 3 more floors to the building, the linear analysis was carried out again, to verify that the calculations and design were in accordance with the NEC 15 standard, checking that the elements had the necessary amounts of steel to generate ductility. After that, the non-linear analysis of the structure was carried out, in which the performance objective was determined, complying with what was established in VISION 2000.
