Column $AB$ is made from high strength pre$-$cast concrete and

reinforced with four $20mm$ diameter $A-36$ steel rods. The allowable

normal stress for the high strength concrete and the steel are

$({}_{\text{a}\text{l}\text{l}\text{o}\text{w}}{)}_{\text{c}\text{o}\text{n}}=13$MPa and $({}_{\text{a}\text{l}\text{l}\text{o}\text{w}}{)}_{st}=170$MPa, respectively.

The modulus of elasticity for high strength concrete is $29$GPa and

for A$-36$ steel is $200$GPa. $($Figure $1)$
