A simply-supported beam has a 3 kip/ft uniformly-distributed load over the left half of its 11-ft span. What is the magnitude of the maximum shear force in the beam?

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

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 = 20 in., b2 = 13 in., d = 21 in., h1 = 4 in., h2 = 12 in., h3 = 10 in., and t = 8 in. There are four No. 6 longitudinal tension bars and No. 3 stirrups at 8 in. o.c.

ACI 318 does not provide rules for designing hanger reinforcement.

The addition of compression reinforcement to an existing beam section increases the ductility of the section.

The shear failure of a slender beam without stirrups is _______.

When faced with severe architectural restrictions on the dimensions of a beam, a designer may be forced to use a singly reinforced section.

Assuming Vs exceeds 4sqrt(f’c)bwd, the maximum spacing for vertical stirrups in the following beam is _____. Let d = 57 in., w = 49.5 in., and t = 5 in. There are five No. 9 longitudinal tension bars and No. 3 stirrups at 7 in. o.c.

For a beam with stirrup hooks, the free end of the bar must extend at least _____ from the hook. Assume b = 12 in., d = 27 in., and that there are four No. 9 longitudinal tension bars and No. 4 stirrups at 10 in. o.c. The stirrup hooks are 135°.

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 = 20 in., b2 = 13 in., d = 21 in., h1 = 4 in., h2 = 12 in., h3 = 10 in., and t = 8 in. There are four No. 6 longitudinal tension bars and No. 3 stirrups at 8 in. o.c.
