A tied short column of square cross-section is subjected to a factored axial load of 2500 kN and a factored bending moment of 175 kN.m. Use a 40 mm clear cover to the ties and a 20 mm maximum aggregate size. It’s required to design the column, including cross-sectional dimensions and longitudinal and transverse reinforcement. Given: fc’ = 25 MPa fy = 400 MPa
