VEd = 1.35 x (2 x 4 / 2) + 1.5 x (1.5 x 4 / 2) = 18.5 kN
The provided reinforcement area is:
As.provided = 4 x π x (20/2)^2 = 1256 mm^2
A square column with a side length of 0.4 meters and a height of 3 meters is subjected to a permanent axial load of 500 kN and a variable axial load of 200 kN. The column is reinforced with 4 longitudinal bars of 20 mm diameter.
As = 0.0013 x 0.3 x 0.6 x 500 = 117 mm^2
Using EC2, the design bending moment is calculated as:
As = 0.0013 x 0.2 x 1 x 500 = 130 mm^2
As.provided = (π x (10/2)^2) / 0.2 = 392 mm^2
