El objetivo de esta investigación es realizar un estudio técnico-económico y comparar diversas configuraciones de columnas en un edificio de acero con un sistema dual compuesto por pórticos especiales con arriostramiento concéntrico. Con este fin se diseñaron y modelaron computacionalmente estructuras con columnas con secciones rectangulares huecas HSS, columnas con secciones tubos rectangulares rellenos de hormigón y columnas con secciones tipo I. Se analizó el comportamiento estructural de estos modelos bajo las mismas cargas y se calculó el costo total de cada alternativa mediante un análisis de precios unitarios. La comparación de las diversas configuraciones se realizó manteniendo una configuración arquitectónica similar y asegurando que los elementos estructurales cumplieran con las especificaciones de la normativa ecuatoriana. La modelación computacional permitió verificar la distribución del cortante basal, la dualidad del modelo, el ajuste del cortante dinámico, el control de modos de vibración y derivas, así como la relación demanda/capacidad, asegurando que todos los elementos estructurales soportaran solicitaciones dentro de sus capacidades. Mediante un estudio económico se obtuvo el presupuesto del edificio. Finalmente, el análisis técnico-económico de los tres modelos permitió identificar la configuración estructural que ofrece la mejor relación costo-beneficio, correspondiéndose con las secciones tubos rectangulares rellenos de hormigón.
The objective of this research is to conduct a technical-economic study and compare various column configurations in a dual-system steel building, composed of special frames with concentric bracing. For this purpose, structures with columns made of HSS hollow rectangular sections, columns with rectangular tube sections filled with concrete, and columns with I-sections were designed and modeled computationally. The structural behavior of these models under the same loads was analyzed, and the total cost of each alternative was calculated through a unit price analysis. The comparison of the various configurations was carried out while maintaining a similar architectural layout and ensuring that the structural elements met the specifications of the Ecuadorian codes. The computational modeling allowed for verification of the base shear distribution, model duality, dynamic shear adjustment, control of vibration modes and drifts, as well as the demand/capacity ratio, ensuring that all structural elements could withstand the imposed loads within their capacities. An economic study determined the budget for the building. Finally, the technical-economic analysis of the three models identified the structural configuration with the best cost-benefit ratio, which corresponds to the rectangular tube sections filled with concrete.
