A W203x28 steel column is 5 meters long and has fixed ends. Estimate the allowable axial loading using the AISC factors and a factor of safety of 2.0. Assume y=250 MPa and E = 210GPa. A table with the cross-section parameters is given below: Table 7.1 Properties of selected wide-flange sections I Designation Mass (kg/m) Area (mm) W203 x 28 27.9 I (about x-x) (10 mm) S (10 mm) I (about y-y) (10 mm) 3600 26.8 262 3.28
