SANCHEZ TIZAPA, Sulpicio et al. Influence of the longitudinal reinforcing steel distribution on the interaction diagrams of circular solid columns. Cienc. ergo-sum [online]. 2022, vol.29, n.3, e173.  Epub 20-Oct-2023. ISSN 2395-8782.  https://doi.org/10.30878/ces.v29n3a7.

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.
