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...

Problem 2. Design and select an ASTM A992 (Fy" 50 ksi) W-shape column to carry an axial dead load of 140 kips and live lond of 420 kips. The column is 30 feet long, and is pinned top and bottom in both axes. In addition, the column is laterally braced about the y-y axis (local weak/minor axis of the section) and torsionally braced at the midpoint. Limit the column size to a nominal 14 in. shape, that is W14 shape...

Design a square tied column to carry axial service loads of 320
kips dead load and 190 kips live load. There is no identified
applied moment. Assume that the column is short. Use f’c =4000 psi
and fy = 60,000 psi. Also, draw the flexural and shear
reinforcement on a sketch.

A beam having b=12in, d=21.5in and h=24in is reinforced with three No.11 (No.36) bars. Material strengths are fy=60,000 psi and fc'=4,000 psi. It is used on a 28 ft simple span to carry a total service load of 2430 lb/ft. For this memeber the sustainted loads include self-weight of the beam plus additional superimposed dead load of 510 lb/ft, plus 400 lb/ft representing that part of the live load that acts more or less continuously, such as furniture, equipment, and...
