A built up column consist of an ISHB 450 @ 87.2Kg/m along with a cover plate of $400mm\times20mm $attached to each flange using black bolts of suitable size. The length of column is 5 m having both ends effectively held in position and also restrained against rotation.

Calculate the limiting load capacity (axial) of this column. Also design the suitable column base and its connection. The column is made to rest on a pedestal of concrete (grade M20) Draw neat sketches to show maximum structural details. Design of concrete pedestal is not required.
