Question 2 A proposed 5-metre-long internal column in a 'rigid' jointed steel structure is to be loaded concentrically with 1000 kN dead and 1100 kN imposed load. Assuming that fixity at the top and bottom of the column gives effective rotational restraints, check the suitability of the column section, 305 x 305 x 118 UC in grade S275 assuming the structure will be: a) braced against sway.

Question 2
A proposed 5-metre-long internal column in a 'rigid' jointed steel structure is to be loaded
concentrically with 1000 kN
dead and 1100 kN imposed load. Assuming that fixity at the top and bottom of the column
gives effective rotational restraints, check the suitability of the column section, 305 x 305 x
118 UC in grade S275 assuming the structure will be:
a) braced against sway.
CR(8)
b) unbraced against sway.
EV(5)
c) What are the considerations for selecting steel sections
EV(7)
d] what accounts for the different structural steel grades?
