5. A doubly reinforced rectangular beam has 3 - 20 mmɸ compression bars and 6 - 28 mmɸ. The breadth and overall depth are 410 mm and 650 mm respectively. Use 10 mmɸ stirrups, 40 concrete cover, fc’ = 20.7 MPa, and fy = 345 MPa. Calculate the following (a) d

1/ Calculate maximum deflection of the beams  (This was solve it) 2/ Check the suitability of the section assuming the code limitation of L/240. 3/ If maximum deflection doesn’t meet the code requirement, propose your solution

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.

I need the answer to the question in reinforced concrete
