Smooth bars are generally not used for longitudinal reinforcement.

An injury referred to as shin splints is often a result of: 

Which of the following should NOT be used to determine the location of bar cutoff points?

There are universally accepted rules for maximum crack widths.

Students are not required to wear a protective mask due to the course being held outside.

Determine the bar-spacing factor, cb, for a simply supported rectangular beam with b = 16 in. and No. 3 stirrups. This beam has five No. 8 bars as longitudinal reinforcement. The clear cover is 1.8 in.

Use ACI 318-14 Table 25.4.2.2 to determine the development length for the straight tension bars (no hooks) in a rectangular beam with b = 16 in. and d = 23 in., four uncoated No. 8 Grade 60 bars placed in the top of the beam, and No. 4 Grade 40 stirrups located every 10 in. along the span. Assume 8,000-psi normal-weight concrete and a clear cover of 1.75 in.

Heads can be attached to one or both ends of a bar by internal threads on the head mating to the bar, welding or forging onto the bar, or by a separate nut used to secure the head onto the bar.

The fatigue strength of stirrups is less than that of longitudinal bars.
