Design column for axial load only. Include the design of ties or spirals and a sketch of the cross sections selected, including bar arrangements. All columns are assumed to be short, and form sizes are available in 2-in. increments Round spiral column: PD = 300 k, PL = 400 k, fc' = 3500 psi, and fy = 60,000 psi. Initially assume rhog = 4%.
