It was proposed to set up a temporary camp for vaccination. The columns had 4 angles of ISA 50 × 50 × 6 in its corners. The radius of gyration of the angles in the x-direction is 10 mm and in the y direction is 15 mm. The overall slenderness ratio of the built-up column is 40. What is the maximum distance between the lacing bar attachments at the fabricated columns as per IS 800 : 2007?
