A short rectangular column 300 mm on one side and 400 mm on the other side. It is reinforced with 8-20-mm-diameter longitudinal bars equally distributed to the shorter sides of the column. The centroid of the bars are 70 mm from the concrete surface. Use f’c = 21 MPa and fy = 415 MPa. Determine the nominal compressive force (kN) on concrete only when the column is at balanced condition with bending about the strong axis.

Question
A short rectangular column 300 mm on one side and 400 mm on the other side. It is reinforced with 8-20-mm-diameter
longitudinal bars equally distributed to the shorter sides of the column. The centroid of the bars are 70 mm from the
concrete surface. Use f’c = 21 MPa and fy = 415 MPa.
Determine the nominal compressive force (kN) on concrete only when the column is at balanced condition with bending about the strong axis.
