The provided reinforcement area is:
The required reinforcement area is calculated as:
As = 0.0013 x 0.2 x 1 x 500 = 130 mm^2
As = 0.01 x 0.4 x 0.4 x 500 = 800 mm^2
The column is checked for buckling:
The provided reinforcement area is:
Using EC2, the design bending moment is calculated as: worked examples to eurocode 2 volume 2
As.provided = (π x (10/2)^2) / 0.2 = 392 mm^2
