QUESTION 1 The 305 x 305 x 97 kg/m H-section column is shown in Figure 1 below subjected to bending about the major axis only. The column forms part of the multi-storey framed structure and the moments given are at the ultimate limit state and include allowance for second order effects. The ultimate axial load is 1000 kN and includes the self- weight of the member. The major axis is unrestrained over the full height of the column and the minor axis is restrained against lateral movement at third points. Use S355JR steel. (30) 1.1. Check the suitability of the section and comment on your answer.
