La falta de planificación desde una etapa temprana en el sector de la construcción ha dado lugar a un crecimiento vertical, haciendo necesarios edificios cada vez más altos y esbeltos, en consecuencia, los elementos compuestos se presentan como una alternativa que busca cubrir las deficiencias que los materiales muestran al trabajar exclusivamente de manera individual. Partiendo de esto, se realizó un estudio comparativo técnico y económico con el propósito de analizar el aporte que tienen las columnas compuestas dentro de un sistema estructural porticado, para el cual se propuso la modelación de dos estructuras de acero con pórticos especiales resistentes a momentos, una con columnas rectangulares de acero huecas y la otra con columnas rectangulares de acero rellenas de hormigón. Se analizaron parámetros como modos de vibración, cortante basal, derivas de piso, peso propio de la estructura y costos. Como resultado se concluye que la estructura con columnas rectangulares rellenas de hormigón presenta un buen comportamiento estructural utilizando perfiles de menor espesor en comparación a la estructura con columnas rectangulares de acero huecas, lo que se traduce en un menor costo. Además, se evidenció que las columnas compuestas presentan una mayor capacidad de carga axial por compresión.
The lack of planning from an early stage in the construction sector has led to vertical growth, making increasingly taller and slender buildings necessary. Consequently, composite elements are presented as an alternative that seeks to cover the deficiencies that the materials show when used exclusively. Starting from this, a comparative technical and economic study was conducted to analyze the contribution that composite columns make within a framed structural system. For this purpose, the modeling of two steel structures with special moment frames was proposed: one with hollow rectangular steel columns and the other with rectangular steel columns filled with concrete. Parameters such as vibration modes, basal shear, floor drifts, structure’s own weight, and costs were analyzed. As a result, it is concluded that the structure with rectangular columns filled with concrete exhibits good structural behavior using thinner profiles compared to the structure with hollow rectangular steel columns, which translates into lower costs. Additionally, it was evidenced that composite columns have a greater axial load capacity due to compression.
