    Seismic vulnerability in essential structures has been a subject of little analysis despite the importance that a building of this type entails, therefore, this research covers the constructive reality of the new unit of the Basic Hospital El Puyo, a structure built with regulations In force, however, the lack of technical criteria of the professionals who designed it significantly influenced the construction, generating cracking problems. During the development of this research, it was necessary to assess the vulnerability of this structure through quick visual inspections and the application of forms with the NEC 2015, FEMA P-154 and FUNVISIS methodologies. Then, non-destructive tests of concrete and soil tests were carried out in order to verify that the design plans have been respected. Subsequently, a mathematical model of this structure composed of two blocks was analyzed using structural design software, where, through a linear static analysis, it turned out that it presented torsion in one of its blocks, which is why a reinforcement was proposed. structural by means of steel stiffening diagonals in certain side frames. On the other hand, the current seismic performance of blocks 1 and 2 was considered, through a non-linear static analysis, obtaining as a result, that they do not meet the performance level for the rare design earthquake, since, the point The performance of these blocks is outside the capacity curve, its resistance being insufficient to meet the seismic requirements; Thus, under this criterion, the pushover was executed with the two reinforced structures, verifying that there is a good seismic performance. Finally, the soil-structure interaction analysis was carried out, verifying that the hospital unit presents permitted differential settlements.
