Aplicación del software etabs para la evaluación de la estructura de hormigón armado del edificio de industrial frente al comportamiento sísmico del 16 de abril del 2016

Abstract

This work degree comprises Etabs in the implementation of software for the evaluation of the reinforced concrete structure Industrial building against the seismic behavior of 16 April 2016. The objective of this research is to study the effects that modeling with masonry and non-masonry, entering the spectra of the earthquake on April 16, 2016 and the design spectrum of the Ecuadorian Construction Standard NEC 2015. To achieve this goal the Etabs 2015 software, version 15.2.0 was used, two models one with the contribution of the masonry and the other model without masonry were analyzed; in the case of the model with masonry it was necessary to introduce in the ownership of the masonry compressive strength of the material and its modulus of elasticity; so it was necessary compression tests of masonry. a static analysis, dynamic analysis spectrum of the NEC-2015 and dynamic spectrum analysis of the earthquake of 16 April 2016 the dynamic properties of the structures were analyzed with Ritz vectors and eigenvectors, was conducted to compare the efficiency in computing modes in buildings with masonry and non-masonry. From this study it can be concluded that: Ritz vectors are more efficient in calculating ways in buildings with masonry and non-masonry, because with fewer modes a higher percentage of effective modal mass that using the eigenvectors is reached. When designing a structure with the inelastic spectrum of the NEC-2015 we are using a reduction factors R and design for less than the actual force, therefore it is implied that there is damage to the structure and can conclude that the value of efforts cutting and moments in the spectrum of 16 a are much larger spectrum of design and therefore the structure can be affected.
