Análisis de vulnerabilidad y reforzamiento del edificio de la Facultad de Ingeniería en Sistemas, Electrónica e Industrial de la Universidad Técnica de Ambato mediante la medición de vibraciones.

Abstract

The evaluation of the degree of seismic vulnerability of the structure was carried out by using two methodologies. The qualitative one where a quick visual inspection was carried out with the use of matrices proposed by FEMA 154, the NEC 2015 standard and the National Secretariat for Risk Management, with which a high vulnerability was determined with the first two matrices, while with the third a low vulnerability for which it is highlighted that a more detailed evaluation is needed. With the information collected through the use of these matrices and in situ tests, a more complete and detailed study was elaborated; Therefore, with the quantitative methodology with a linear analysis, the vibration period and the floor drifts that comply with the provisions of the NEC were obtained, in addition a non-linear or Pushover analysis was presented where it was observed that the structure presents a performance capacity according to the specifications of the standard with a level of Life Safety. With the vibration method proposed by the AISC guide 11, it was determined that it complies with and falls within the limits established in the aforementioned standard. Finally, it was established that the structure is stable and complies with the guidelines of the standard in the event of a seismic event, so it is not necessary to reinforce the structure.
