Question 2 A 254 x 254 x 73 kg/m universal column section in grade S275 steel is used for a building column which has an overall height of 6m between end restraints. The column is effectively held in position at both ends but partially restrained in direction at the top end only. An intermediate lateral restraint against minor axis buckling is provided at mid-height. No intermediate restraint is provided against major axis buckling. Using BS 5950-1 guidance Determine the design ultimate axial compression load capacity of the column (in KN). (12 marks) For the column load obtained in (i) above, design a suitable size of the column base plate if the foundation concrete characteristic strength is 30N/mm (8 marks)
