A circular hollow section (CHS) member is to be used as an internal column in a multi- storey building. The column has pinned boundary conditions at each end, and the inter-storey height is H m. The critical combination of actions results in a design axial force of Nea kN. Select a suitable CHS section and assess the suitability of application in grade S steel. NEd [H]
