Problem $3$:

A W $25073k\frac{g}{m}$ is used as column and is supported by a

concrete pedestal having a top surface of $450mm450$

$mm.$ The column carries a column dead load of $436kN$ and

a live load of $646kN.$ Assume less than full area.

Properties of $W25073$

$bf=254mm$

$d=253\mathrm{.}49$

$If=14\mathrm{.}22mm$

$f^{\text{'}}c=21$Mpa

$Fy=248$MPa

Find the dimension of the base plate $"B".$

Compute the dimension of the cantilever strip of

base plate to be used for computing the base plate

thickness. N $=350$ mm
