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...
A column 400 mm × 400 mm cross-section is reinforced with 4N32 bars and R10ties@160c/c. N32 concrete is used. A cover of 20 mm is provided. The column is subjected to an axial force of 600kN and a bending moment of 300 kN.m. The column is pinned at the bottom and is restricted at the top. The length of the column is 4.0 m. Check if the reinforcement provided is OK and if not re-design the column.
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.

Question #2 (20 points) A (a) A Composite column made of reinforced concrete was constructed on a very rigid foundation. The column was constructed at 25 °C and in this temperature, there was no stress in the system. The column is exposed to axial loading (or stress) of 2000 psi as shown in the picture. The column has a thickness of 8 in, a width of 3 in, and a length of 13 ft. Six #6 longitudinal bars (each has...
Select reinforcement for the T-beams in the simply-supported floor system shown below. The system is 26-foot-long and subjected to its own self-weight and a service live load of 200 psf. Take the compressive strength of the concrete to be fe' = 3 ksi and the yield stress of the rebar to be fy = 60 ksi.
