Análisis comparativo de sistemas estructurales en el diseño de un edificio de recepción para finca turística: Evaluación de estructuras mixtas, Hormigón armado y acero estructural para grandes luces.

Abstract

The present project involves a comparative evaluation of three types of structural systems: steel frames, reinforced concrete walls, and mixed systems for a two-story tourism estate building located in the Salitre, featuring large spans, with the aim of determining the optimal structure. This building is situated on soil with low bearing capacity. Additionally, it faces challenges in covering large spans, such as high costs, limited information, complexity, and a lack of comparative studies in seismic zones. For the development of this project, the waterfall methodology was implemented. Applicable codes and standards were identified, design loads were determined, structural elements were designed, results were verified, and a comparative evaluation was carried out. The results showed a high flexibility for the steel frame system, a cost of $186/m², a weight of 50.31 kg/m², and short construction times. The reinforced concrete wall system exhibited high stiffness with a weight of 321.5 kg/m², a cost of $202/m², and long construction times. The mixed system, being the lightest, most economical, and featuring intermediate construction times, was the most advantageous. Finally, it was determined that the most beneficial structural system is the mixed system, as it leverages the stiffness of concrete and the ductility of steel. It is lightweight with a weight of 37.07 kg/m², economically viable at a price of $149/m², offers good energy dissipation, and has suitable construction times.
