According to ACI 318, the strength-reduction factor, φ, for shear and torsion is _____.

Reinforced concrete structures normally do not crack when carrying service loads.

A continuous beam’s flexural reinforcement must extend at least _____ from the point where it is no longer needed to resist tension. Assume f’c = 4,000 psi, fyt = 40,000 psi, b1 = 27 in., b2 = 11 in., d1 = 6 in., d2 = 17 in., and that there are three No. 6 longitudinal tension bars and No. 3 stirrups at 7 in. o.c. The stirrup hooks are 90°.

Crack widths are a concern for several reasons. Which of the following is NOT one of these reasons?

Use the Factor Theorem to determine whether the first polynomial is a factor of the second polynomial. x – 5; 3×2 + 7x + 40 (5 points)

If φVc = 67 kip and Vu = 17 kip, are stirrups required?

A beam has dimensions of b = 14 in., h = 30 in., d’ = 2.5 in., and d = 27.5 in. It is reinforced with 2 No. 5 bars on the compression side and 4 No. 8 bars on the tension side. The concrete strength is 2,800 psi, and the yield strength of the reinforcement is 60,000 psi. If the depth of the neutral axis is c = 5.68 in., determine the strain in the compression reinforcement, ε’s.
