Homework: Column & Foundation Design and Concrete Quality

Design smallest possible square tied concrete column to safely carry the following floor loads for a $4-$story building. The height of each floor is $12ft.$ Assume column will be stocky. Design an interior ground floor column. Assume Pdead $=100$ kips and Plive $=170\mathrm{.}50$kips at the bottom of the column. Select economical column dimensions, longitudinal reinforcement $($use #$9$ bars$),$ and size, spacing, and layout of lateral ties. Check your answer by solving ACl column formulas for an axially loaded stocky column. Use $f_c^{\text{'}}=4000$ and $f_y=60$ksi. $(25$ Points$)$
