An example of a shear reversal would be a _______ load.

A 120-mm-long beam supports a load of P = 31 N at midspan. The cross section is rectangular with width b = 26 mm and height h = 40 mm. Determine the magnitude of the horizontal shear stress at the centroid of the cross section.

Flexure-failure loads are more variable than shear-failure loads.

Flexure-failure loads are more variable than shear-failure loads.

Determine the size modification factor, ψs, for a rectangular beam with b = 18 in. and d = 20 in., three uncoated No. 8 Grade 60 tension-reinforcement bars placed in the bottom of the beam, and No. 3 Grade 60 stirrups located every 6 in. along the span. Assume 6,000-psi lightweight concrete and a clear cover of 1.5 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 = 24 in., five galvanized No. 6 Grade 60 bars placed in the bottom of the beam, and No. 4 Grade 40 stirrups located every 6 in. along the span. Assume 8,000-psi lightweight concrete and a clear cover of 1.75 in.

Determine the transverse reinforcement index, Ktr, for a rectangular beam with b = 18 in. and d = 24 in., five epoxy-coated No. 6 Grade 60 tension-reinforcement bars placed in the top of the beam, and No. 3 Grade 60 stirrups located every 6 in. along the span. Assume 5,000-psi normal-weight concrete and a clear cover of 1.5 in.

A 125-mm-long beam supports a load of P = 40 N at midspan. The cross section is rectangular with width b = 30 mm and height h = 40 mm. Determine the magnitude of the horizontal shear stress at the centroid of the cross section.
