Prob. 3.5-5. A 15-in.-diameter, reinforced-concrete column has six 9/8-in.-diameter steel reinforcing rods uniformly spaced around a circle. E, = 3 x 10³ ksi and E, = 30 x 10³ ksi. (a) Determine the axial stress in the concrete and the axial stress in the steel under an axial load P = 150 kips. (Note: Treat the six reinforcing bars as a single element, and treat the concrete as a second element. Use the net area of concrete.) (b) How much does the column shorten under the 150-kip load? d = 15 in. P = 150 kips P3.5-5 L = 8 ft
