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, b = 13 in., d = 17 in., and that there are four No. 7 longitudinal tension bars and No. 3 stirrups at 7 in. o.c. The stirrup hooks are 135°.

If a beam is supported by a girder of essentially the same depth, the compression fans that form in the supported beam tend to push the bottom off the supporting beam.

A 123-mm-long beam supports a load of P = 32 N at midspan. The cross section is rectangular with width b = 25 mm and height h = 45 mm. Determine the magnitude of the horizontal shear stress at the centroid of the cross section.

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.
