a) A solid cylindrical steel column 3 m high and has a diameter of 135 mm and has been design assuming a failure stress of 270 N/mm². Immediately after ejection, a weight of 4000 kN is applied to the head of the column. 1) Determine whether the column requires replacing? [6 marks) ii) The maximum deformation in the column. [4 marks] iii) What is the maximum applied load that the column can withstand? [3 marks] b) A concrete column having a modulus of elasticity 20 GN/mºis reinforced by two steel bars of 25 mm diameter having a modulus of 200 GN/m². Calculate the cross-sectional area of the square section strut of the stress in the concrete is to not exceed 7 MN/m² and the load is to be 400 kN. [12 Marks]
