3.) A concrete square column 250 mm x 250 mm is to be reinforced by deformed steel bars to carry a load of 500 kN. the properties of concrete and steel are as follows: Deformed Steel bars Concrete 6 120 Allowable Stress (Mpa) Modulus of Elasticity (Gpa) 200 14 Determine the number of deformed steel bars and show a detail of the cross-section of your design. Commercially available deformed bars are 12 mm, 16 mm, 20 mm, 25 mm, 32 mm, and 36 mm in diameter.
