Assignment Help Civil Engineering
##### Reference no: EM13297048

A circular concrete column of 300 mm diameter, is reinforced with six identical steel bars. If the column is subjected to an axial compressive force of 800 kN, determine the required diameter of each reinforcing steel bar so that one-third of the load is carried by the steel and two-thirds by the concrete. Assume Esteel= 200 GPa and Econcrete= 25 GPa.
