5. A short reinforced column of section 300 mm x 400 mm is to be reinforced with 6 nos. of steel bars and is required to carry an axial load of 1350 kN. The stress in the concrete must not exceed 8 N/mm2 and the stress in the steel must not exceed 180 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 = 10 kN/mm, Steel = 200 kN/mm. 300 mm 400 mm 5.
