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

"This study component focuses mainly on analyzing the structural behavior and cost of using lightweight concrete with compressive strength f'c=35 MPa for a 6-story building located in the city of Quito, intended for apartments. For this, a special earthquake-resistant frame structure is proposed, made up of dropped beams and columns. As a starting point, a typical architectural proposal is proposed, in whose internal distribution there are departments and considering the respective distribution of lights. The building has no basement and has 6 floors above ground level, including the roof slab. The pre-design was developed considering previously the material’s data, mainly the weight of the lightweight concrete used, as well as its compressive strength f'c. Continuing with the study, three-dimensional modeling and structural analysis were performed using ETABS 19 software. Two linear analyses, linear static analysis and spectral modal analysis were performed. Afterwards, it was verified that the structure behaves adequately for the subsequent structural design, paying attention to the modification factors in ACI 318-19 dictated for lightweight concrete. Subsequently, the structural plans of the designed elements were made, among these slabs, beams and columns. Finally, the volumes or quantities of work for items of concrete and steel reinforcing rods were obtained to obtain a reference budget for the building."
