Figure 1, shows a steel column with a design axial compressive load, N* = 700kN and a design moment, M* = 390kNm about the major axis at the top. It is pinned about both axes at the base and at the top. The column is a 310UC137, Grade 300. (a) Calculate the buckling resistance, oNc, for this column. (8 marks) (b) Calculate the lateral torsional buckling moment resistance, M, for this column. (7 marks) (5 marks) (c) Check this column for the combined axial load and moment. DATA: 310UC137 has dimensions: d=321mm, b=309mm, t-21.7mm, t=13.8mm, r₁=16.5mm, d,=277mm, d₁/t=20.1, (b-t)/2t 6.80, A=17500mm², I=329x10 mm, Z=2050000mm³, S=2300000mm³, r=137mm, I=107x10 mm, Z=691000mm³, S=1050000mm³, r=78.2mm, J=2520000mm, L=2390x10 mm", using the usual notation from AS4100.
