In which type of splice is the force in one bar transferred to the concrete, which then transfers it to the adjacent bar?

Determine the size modification factor, ψs, for a rectangular beam with b = 18 in. and d = 20 in., five epoxy-coated No. 9 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 4,000-psi lightweight concrete and a clear cover of 2 in.

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

Brittle materials fail due to maximum shear stress rather than principal stresses.

Determine the casting-position modification factor, ψt, for a rectangular beam with b = 17 in. and d = 23 in., four epoxy-coated No. 7 Grade 60 tension-reinforcement bars placed in the bottom of the beam, and No. 3 Grade 60 stirrups located every 12 in. along the span. Assume 8,000-psi lightweight concrete and a clear cover of 1.5 in.

A 125-mm-long beam supports a load of P = 48 N at midspan. The cross section is rectangular with width b = 29 mm and height h = 60 mm. Determine the magnitude of the horizontal shear stress at the centroid of the cross section.

Researchers studying reinforced concrete have considered a mechanical explanation of Vs to be the Holy Grail.

Determine the transverse reinforcement index, Ktr, for a rectangular beam with b = 17 in. and d = 23 in., five galvanized No. 9 Grade 60 tension-reinforcement bars placed in the top of the beam, and No. 3 Grade 40 stirrups located every 6 in. along the span. Assume 7,000-psi lightweight concrete and a clear cover of 2 in.
