Problem $2$

Determine the design Pu and Mu that must be used for the design of column $AB$ of the shown unbraced frame. Given, $f^{\text{'}}c=28$MPa and $fy=420$MPa,$Ec$ for beams and columns $=24870000kN.m^2.$ Unfactored end moments for column $AB$ and normal forces in all columns in the floor of $AB$ are shown in the table below. All columns have fixed supports.
