Problem – 1: Design a round spiral column to support an axial dead load of 800 kN and an axial live load of 1350 kN. Assume that 2% longitudinal steel is desired, f: = 27.6 MPa and fy = 414 MPa. Use 25 – mm main reinforcement and 10 – mm lateral reinforcements with 30 mm steel covering. Make sure to include both the cross-sectional profile as well as the lateral profile of the design. Draw your diagrams neatly, this is a design. Problem – 2: Instead of a round spiral column, design a square tied column for problem-1. Problem – 3: Instead of a round spiral column, design a circular tied column for problem-1.
