A column 400 mm × 400 mm cross-section is reinforced with 4N32 bars and R10ties@160c/c. N32 concrete is used. A cover of 20 mm is provided. The column is subjected to an axial force of 600kN and a ben...
A column 400 mm × 400 mm cross-section is reinforced with 4N32 bars and R10ties@160c/c. N32 concrete is used. A cover of 20 mm is provided. The column is subjected to an axial force of 600kN and a bending moment of 300 kN.m. The column is pinned at the bottom and is restricted at the top. The length of the column is 4.0 m. Check if the reinforcement provided is OK and if not re-design the column.
