Análisis comparativo económico estructural de un edificio de 15 pisos en la ciudad de quito, diseñado con acero de refuerzo grado 60 - acero de refuerzo grado 80 - hormigón normal f'c 28 mpa y hormigón liviano f'c 28 mpa.

Abstract

The purpose is to carry out a structural economic comparison of four modeling proposals for a residential-commercial building of 15 stories and 5 basements located in González Suárez Avenue in the Metropolitan District of Quito. The comparative variables to be used in each case study correspond to the main construction materials, such as concrete and reinforcing steel, which present variations with respect to the conventional types (conventional concrete and grade 60 reinforcing steel), these being lightweight concrete and grade 80 high strength reinforcing steel. The structural comparison will cover the main parameters that define a good seismic-resistant behavior in a building, such as drifts, vibration modes, periods, deflections, actions of the elements, and basal shear, which are obtained by means of linear analysis. On the other hand, an analysis that considers the behavior of the structure in its inelastic range, such as Pushover or nonlinear static analysis, will be used. Based on the results obtained from the structural analysis, reinforcement detailing drawings will be prepared, taking into consideration the specifications of the ACI 318 (2019) and NEC - 15 (2015) standards. These will allow quantifications of materials and volumes of work for the preparation of budgets through reference prices in the Ecuadorian market for the year 2022. Finally, through an analysis of alternatives, the proposal with the best performance and price will be defined.
