Análisis comparativo estructural de un edificio aporticado de 6 pisos en la ciudad de Quito, usando el método de diseño basado en fuerzas variando los materiales.

Abstract

The accelerated population growth and housing deficit in the city of Quito opens the need to search for new materials that allow reducing the cost of buildings without affecting their resistance and comfort. The purpose of this component of the Curriculum Integration Project is to encourage the use of high-strength concrete with a normal specific weight of 60 MPa for a medium-height framed structure (6 stories), analyzed under the Force-Based Design of the NEC and designed with the most recent reinforced concrete regulations. The purpose of using this material is to reduce the cross-section of the members made of concrete, the amount of reinforcement and, in general, to obtain a lower price per square meter compared to those obtained in the market but considering that it will have the same or better structural behavior compared to other types of concrete. As a starting point, an architectural proposal was defined following the Municipal Ordinances of the city of Quito, which define the minimum dimensions of spaces. After pre sizing, model the structure in the ETABS program, perform the structural analysis and design under the NEC-15 regulations for Reinforced Concrete, Seismic Hazard and ACI 318-19. Finally, with the dimensions of the final design, a total building cost of $179.41 per square meter was obtained. Based on the results, certain advantages were established that represent the use of this kind of concrete in Ecuador and its impact on the local economy.
