Estudio comparativo técnico-económico entre dos modelos de edificios de diez pisos: sistema dual de estructura de hormigón armado con losa postensada sin adherencia y estructura de acero con losa compuesta tipo plataforma de acero

Abstract

The present Project exposes the comparison between two structural proposals for a building with unique architectural characteristics evaluated to present a more economical alternative and with a better structural performance in the face of the most critical eventuality. The structural systems must comply with certain previous criteria such as dual systems. The first structure proposed is a reinforced concrete structure with post-tensioned concrete slabs designed to cover the demands presented by the large lengths between the columns (8 m to 12 m). The design of this structural system also corresponds to suspended beams and columns of reinforced concrete as a special moment frames (SMF) and reinforced concrete structural shear walls. The second is a steel structure with Steel Panel slab plate with the same architectural features and composed by hot rolled beams, composite columns which make up SMF and the reinforced concrete shear walls. Also, a budget is determined for each structure for the building and a work execution schedule will be elaborated for each. This will be done with Gantt Charts and timelines. Both structural proposals are construction technologies that are imposes as trends in the construction market in Quito, so a good response of both alternatives is expected.
