Design the flexural reinforcement of a tied column in a reinforced concrete frame is subjected to the following loading scenarios: a. pd = 240 kips, md = 140 k-ft, pl = 160 kips, ml = 300 k-ft b. pd = 200 kips, md = 140 k-ft, pl = 140 kips, ml = 220 k-ft c. pd = 300 kips, md = 120 k-ft, pl = 300 kips, ml = 200 k-ft d. pd = 380 kips, md = 130 k-ft, pl = 265 kips, ml = 180 k-ft e. pd = 220 kips, md = 140 k-ft, pl = 140 kips, ml = 220 k-ft in your design use concrete with compressive strength of 4,000 psi and grade 60 steel bars. (hint: initially consider the maximum axial load demand. after determining the column dimensions, check for all cases to find the required reinforcement ratio.)
