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.
The design punching shear resistance is:
Ncr = π^2 x 25 x 0.4^4 / (3^2) = 2761 kN worked examples to eurocode 2 volume 2
The column is checked for buckling:
The beam is checked for shear resistance: A square column with a side length of 0
The provided reinforcement area is:
Using EC2, the design bending moment is calculated as: worked examples to eurocode 2 volume 2
λ = 3 / 0.4 = 7.5
