Q-An RC square column of size 600 mm is constructed to carry an unfactored load of 3000 kN. The ends of the column are restrained from displacement but free to rotate and is casted with M-25 concrete. The area of Fe-415 steel required to carry the given load considering that the column is short and loaded with minimum eccentricity is

The light rigid bar ABCD shown is pinned at C and connected to two vertical rods. The bar was initially horizontal, and the rods were stress-free before the load P= 20 KN is applied.
