The roof of a hall has 5 inch thick slab supported on beams having 30 feet span. Beams are spaced 10 feet c/c and have been cast monolithically with slab. Overall depth of the beam being 24 inch and width of beam web being 14 inch. Calculate the steel reinforcement area for the beam for a total factored load of 3000 lb/ft over length of the beam. Use fc’=3000 psi and fy=60000 psi.

Given a concrete column that would be required to support loads of Pu=400kips and Mu=50 kip-feet, we will determine the column interaction curve and decide if the column is adequate for this particular application. The column will be a 14”x14” square, tied column with #9 bars at the corners. The center of the reinforcement in each corner is 3” from each of the sides. The f’c of the concrete is 4 ksi and the reinforcement is Grade 60.  Determine if the column is acceptable for this application. Calculate the value of Mu and Pu.
