15 points 9. A rectangular concrete beam of width b=24 in. is limited by architectural considerations to a maximum total depth h=16 in. It must carry a total factored load moment Mu 400 k-ft. Design the flexural reinforcement for this member, using compression steel if necessary. Allow 3-in, to the center of the bars from the compression or tension face of the beam. Material strengths are fy=60 ksi and fc=4 ksi. Select reinforcement to provide the needed areas, complete necessary...

1) [Design] A reinforced concrete column is to be sized to carry pure axial compressive load. According to ACI 318, what is the smallest possible cross-sectional area (Ag) that the column can use in design supporting an axial dead load of 200 kips (unfactored) and live load of 400 kips (unfactored). Use fc = 4,000 psi and fy = 60 ksi. Assume pe = 0.08 and ties for transverse reinforcement. Be sure to include the appropriate design factors and use...
