The column has dimension of 500 mm x 500 mm and carries an axial
load of 1210 KN dead load and 650 KN live load. Allowable soil
pressure is 240 Kpa. There is 0.7 m height of soil having a unit
weight of 15.74 KN/m3, fc’ = 20.7 Mpa, fy = 276.5 Mpa. The footing
section is 2.8 m x 2.8 m with a 600 mm thickness. Use 25 mm
diameter main bars.

A short reinforced concrete column is subjected to a
1000 kN axial compressive load. The moduli of elasticity of plain
concrete and steel are 25 GPa and 207 GPa, respectively, and the
cross-sectional area of steel is 2% of that of the reinforced
concrete. Considering the column as a structural member made of a
composite material and subjected to load parallel to the steel
rebars, calculate the following:

Prompt: Design the representative column for the factored axial
load only. Assume pin connections top and bottom. If you want, you
might consider designing for 75% of capacity, to allow for
remaining capacity for the lateral loads to be determined in the
future.
I'm Suppose to design a Concrete Column; many assumptions can be
made, such as type/strength of concrete. The calculated axial load:
Pu= 88.2 Kips
