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 : análisis estructural, diseño estructural de edificio aporticado de 6 pisos con acero estructural.

Abstract

In this study, the structural design of a 6-story building is carried out, whose architectural characteristics in plan correspond to a model that represents the everyday residential and commercial buildings in the central area of the city of Quito. The first floor was destined for commercial premises, while the upper floors are considered as apartments. Within the design, ASTM a-36 structural steel was considered as the main construction material; however, reinforced concrete was designated for the design of four structural walls located at the ends of the building under the parameters and requirements set forth in the NEC-15 (Ecuadorian Construction Standard), ACI 318S-19 (Structural Concrete Regulation), AISC360-16 (Specifications for Structural Steel Buildings) and AISC 341-16 (Specifications for Structural Steel Buildings), with the use of Etabs software, in which a force-based analysis was performed, in order for the building to comply with the standard requirements. The architectural drawings were the starting point in the methodology of this study, followed by the respective pre-dimensioning of the structural elements for their subsequent analysis before the application of gravity and seismic loads in order to obtain the sections of the final structural design. Finally, based on the resulting drawings, the unit price analysis of the project was performed, requiring a total budget of US$524.530,45.
