Question: problem 3 a 6 m high steel column fixed at...

Question details

Problem 3 A 6 m high steel column, fixed at its lower end, is to be a fabricated I section as shown. It is to carry a compressive load of 92 kN at the central axis O of the section. Determine the minimum dimensions of the column to resist buckling for: 10 mm 10 mm LORD ol a) The upper end free. b) The upper end pinned but restrained in thee horizontal direction by other structural members. c) What are the compressive stresses in each case? d) Select a standard RSC to replace the fabrication. 10 mm Take E as 200 GN/m2.
