Análisis dinámico lineal del edificio de la Facultad de Ingeniería en Sistemas de la Escuela Politécnica Nacional aplicando los métodos: modal espectral y tiempo historia, mediante el uso de paquetes computacionales

Abstract

In this project, we analyze the elastic performance of displacements of the building of the Faculty of Engineering in Systems of the Escuela Politécnica Nacional applying the dynamic linear methods: Spectral Modal and Time History, using Matlab and Etabs. The seismicity of Ecuador and the seismic design methodology proposed by the current Construction Standard are briefly studied. It is described architecturally and structurally the aforementioned building, idealizing it as a set of flat porches united by rigid floors. In the Spectral Modal analysis, the inelastic acceleration spectrum of the NEC 2015 is used, while in the Time History analyzes a set of 10 accelerograms corresponding to 5 seismic events occurring around the world are used that are scaled to the inelastic spectrum, applying the procedure set forth by ASCE / SEI 7. The results obtained are compared with the three models proposed, in order to establish how influential the presence of masonry in the stiffness of the building is. Finally, it is determined whether the maximum inelastic drifts calculated through the dynamic methods, surpass or not; the maximum drift allowed by the NEC 2015 standard.
