Reducción de la vulnerabilidad sísmica de estructuras ocupacionales de acero en el cantón Ambato
(Universidad Técnica de Ambato. Facultad de Ingeniería Civil y Mecánica. Maestría en Ingeniería Civil con Mención en Estructuras Metálicas, 2022-03) Jiménez López, Geovanny Gabriel; López Villacis, Gonzalo Eduardo
In this degree work, a seismic vulnerability study is carried out for two representative structures that constitute the typical occupation given to steel buildings constructed within the urban area of Ambato Canton. These buildings, according to the NEC-2015, are categorized as essential and special type structures respectively. As an initial part, a preliminary design check was performed using the design spectrum prepared according to the standard for this sector, where compliance was reviewed in terms of floor drifts, soft floor and torsion in plan. Subsequently, by means of a nonlinear pushover static analysis, the capacity of the structure and its performance level in the presence of moderate and extreme earthquakes were determined. Likewise, certain influences of the infill masonry used in this type of structures were determined, and finally, according to the performance obtained, a reinforcement was proposed through the use of concentric diagonals and energy dissipaters in order to improve their performance level and avoid their collapse.
