A 7.5 m, A-36 steel (Fy=248 MPa, Fu = 400 MPa) steel exterior column has an effective length factor of 1.3 and a radius of gyration of 81.8 mm. If the service axial compressive force of column is 1275 kN and the Demand-Capacity ratio for the moments is 0.64, determine its required cross- sectional area of the column using ASD and LRFD.
