Example $1$:

Design a $6m$ tall column to support an unfactored dead load of $410kN$ and unfactored live load of $340kN.$

$F^{\text{'}}c=28$MPa

$Fy=420$MPa

Assume that the column braced and $K=1\mathrm{.}0.$

The bending moment diagram for the column is shown in Figure $11\mathrm{.}9.$

$MD=31kN*m$

$ML=26kN*m$

$MD=21kN*m$

$ML=17kN*m$
