Determine whether the reinforced concrete column cross-section shown below would be suitable to resist an axial load of 1750kN. Assume that the design compressive strengths of the concrete 20N/mm2 and steel reinforcement are 375 N/mm2 respectively.

TASK 1
With the use of diagrams, describe the slenderness ratio and the effective length of a column. Give references where necessary, especially in the use of illustrations and diagrams
