Seismic vulnerability is a magnitude that allows quantifying structural damage, failure modes and resistant capacity under the action of an earthquake, which is based on the characteristics of the structure. The present work was framed in the vulnerability analysis of metallic structures of the Santa Rosa parish, Zone 2, which has a high level of seismic hazard due to its location and proximity to several geological faults. It was found that most of the metal structure buildings analyzed present a high vulnerability index that indicates that they would suffer great damage in the event of an earthquake. The evaluation criteria used were based on three methodologies: NEC 15, FEMA P-154 and FUNVISIS: perform a more exhaustive analysis, draw vulnerability and seismic risk maps and identify a representative building to perform a detailed analysis and propose a reinforcement proposal, in this building three types of analysis were performed: static, spectral modal and Pushover to identify the critical points of the structure that should be reinforced.
