6. A short reinforced column of section 250 mm x 500 mm is to be reinforced with 6 nos. of steel bars and is required to carry an axial load of 1050 kN. The stress in the concrete must not exceed 6 N/mm and the stress in the steel must not exceed 160 N/mm. Determine the diameter required for the bars and the subsequent stress occurring in the concrete and the steel under the specified load. Young's moduli: Concrete = 12 kN/mm, Steel = 190 kN/mm. 500 mm 250 mm
