Column AB is made from high strength pre-cast concrete
and reinforced with four in diameter A-36 steel rods. The
allowable normal stress for the high strength concrete and
the steel are (allow) con = 2.6 ksi and (allow) st = 24 ksi,
respectively. The modulus of elasticity for high strength
concrete is 4.2 x 10³ ksi and for A-36 steel is
29 x 10³ ksi. (Figure 1)
