The use of high-strength concrete (HSC) has been widely accepted by designers and contractors in reinforced concrete structures, especially heavily loaded column of high-rise building and bridges. To study the strength and deformability of HSC columns subjected to eccentric loading, nine columns were tested under eccentric loading and one column only was tested under axial loading. The investigated parameters were concrete compressive strength, slenderness and rectangularity ratios, and load eccentricity. The concrete compressive strength ranged from 36.0 to 75.0 MPa and the slenderness ratio was ranged from 6.67 to 10.0 while the considered eccentricities ratios ranged from 0.0 to 0.80. Also, comparison between experimental and analytical study was carried. The results indicated that increasing concrete compressive strength resulted in increasing the column strength capacity. While increasing the eccentricity are resulted in decreasing the column strength capacity. Also the comparison between experimental and analytical study indicated that both ACI 318R-14 and ECP 203-07 codes are acceptable and valid to determine both the load and the moment capacity of such columns subjected to eccentric loading if take into consideration the additional moment induced due to column deformations.
