Stress Column Concrete Reinforced Calculation Example # Calculation Example – Reinforced Concrete Column at Stress.

Contents [show]

A rectangular column (400mmX400mm) is constructed of concrete and four steel reinforcing rebars. An axial force of 1000KN is subjected on the column. What is the diameter of the steel bars if the ¼ of the load is transferred to the steel bars and ¾ is transferred to the concrete? ( EST=200GPa, Ec=25GPa)

**Solution**

From the equilibrium of forces:
