A tied column which is subjected to an eccentric load has dimensions of 300 mm x 500 mm which is reinforced with 4 - 28 mm Ø bars arranged as shown in the figure. The concrete cylinder strength f = 27.6 MPa and the steel yield strength fy 414.7 MPa. The column carries a nominal load P₁ at an eccentricity "e" from the y-axis of the column section. If the neutral axis is 125 mm from the right edge of the column section. Neglect the area of concrete displaced by the compression steel bar.
