As the size of coarse aggregate increases, the roughness of the crack increases. This allows higher shear stresses to be transferred across the crack.

The use of compression reinforcement permits the use of more tension reinforcement to decrease the strength of a given beam section while keeping the section compression-controlled.

If φVc = 50 kip and Vu = 58 kip, are stirrups required?

A combination of horizontal and vertical reinforcement is used to restrain cracks from opening too wide.

Which of the following is not a common type of splice?

The shear failure of a slender beam without stirrups is slow and predictable.

Assuming Vs does not exceed 4sqrt(f’c)bwd, the maximum spacing for vertical stirrups in the following beam is _____. Let b1 = 28 in., b2 = 14 in., d = 49 in., h1 = 4 in., h2 = 42 in., h3 = 8 in., and t = 7 in. There are six No. 6 longitudinal tension bars and No. 4 stirrups at 11 in. o.c.

A simply-supported beam has a 3 kip/ft uniformly-distributed load over the left half of its 13-ft span. What is the magnitude of the shear force at midspan?

Which of the following is not a common type of splice?

Where there are several layers of reinforcement, a continuous horizontal opening large enough for the concrete vibrator to pass through should be provided.
