Design of column section for ULS:
The column is checked for applied moment about the design axis. Through inspection: the critical section lies at the top end of the column.
The design axis for the critical load case 3 lies at an angle of 90.00to the X-axis The safety factor for the critical load case 3 is 1.22
For bending about the design axis:
