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...

NAME: PROBLEM #1 A 10" X 18" reinforced concrete beam frames into a column that is 18" wide. Beam reinforcing consists of 3 - #6 bars located at the top of the beam, and #4 stirrups at 6" 0.c. with 2 cover typical. Determine the development length required into the column. If the available development length into the column is not sufficient, utilize a 180 degree hook. Compressive strength of the concrete is 4,000 psi, yield strength is 60,000 psi,...

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...
