Análisis comparativo entre una estructura de concreto armado y estructura metálica,aplicando metodología BIM

Abstract

In the construction industry, the choice of materials and structural design methods is crucial to the success of any building project. Throughout the world, there is a wide variety of methods used in infrastructure construction. However, two main techniques predominate in Ecuador: steelstructure and reinforced concrete construction. Both structural systems have benefits and limitations; therefore, it is essential to analyze the technical and economic characteristics of each one before making a decision. In this academic paper, in order to determine the most adequate structural system from the technical point of view, a comparative analysis of a single-family construction project between a reinforced concrete structure and a steel structure was carried out, applying BIM methodology. The modeling was designed from Revit and Robot Structuralanalysis, thanks to the interoperability and collaborative work between different areas of the project from a single model offered by these computational packages. The structures were designed as seismic-resistant in reinforced concrete and steel structure, according to the parameters established in NEC-15, and as references ACI 318-14 and AISC 360-16. The analysis has verified: vibration period, mass participation, basal shear, floor drift, beam column connection and weight-structure ratio. In relation to the results obtained for the inelastic drifts of both construction systems analyzed inthis research, it could be seen that the steel structure shows a decrease of 29 % in comparisonwith the reinforced concrete structure.
