A column between floors of a multi-story building frame is subjected to biaxial bending at the top and bottom. The column member consists of a Grade S275 steel 305 × 305 UC158 section. Investigate its adequacy if the design load data are as follows: Ultimate axial compression = 2300 kN, Ultimate moments, Top-about major axis = 300 kN m, about minor axis = 50 kN m, Bottom-about major axis = 150 kN m, about minor axis= −80 kN m. Effective length of column = 6.0m
