Influencia de la distribución del acero de refuerzo longitudinal en los diagramas de interacción de columnas sólidas circulares.

The variation of the interaction diagrams for solid circular columns is presented considering the position of the longitudinal rebars. Two of them were considered: a) the first rebar coincides with the vertical longitudinal axis, and b) the first rebar is placed out of phase to the right of the semi-angle between two rebars. A variation of -4.2% to 6.6% was evaluated in 32 pairs of interaction diagrams for columns reinforced with a variable quantity of rebars (from 6 to 11 rebars) and steel ratios ranging from 2.42 to 4.13%; the error is 2%, 4%, and 7% in columns reinforced with 10, 7, and 6 rebars, respectively. Therefore, considering the position of the rebars in columns with a small amount of reinforcement (6 to 9 rebars) is very important for the design process. [ABSTRACT FROM AUTHOR]
