If φVc = 43 kip and Vu = 54 kip, are stirrups required?

A beam has dimensions of b = 14 in., h = 28 in., d’ = 2.5 in., and d = 25.5 in. It is reinforced with 2 No. 5 bars on the compression side and 5 No. 8 bars on the tension side. The concrete strength is 4,000 psi, and the yield strength of the reinforcement is 60,000 psi. If the depth of the neutral axis is c = 5.216 in., determine the strain in the compression reinforcement, ε’s.

Because a slab is thinner than the beams supporting it, the concrete in the slab shrinks more rapidly than the concrete in the beams.

At a point subjected to plane stress, the stresses are σx = 20 ksi, σy = 10 ksi, and τxy = –10 ksi. Determine the angle θp corresponding to the orientation of the principal planes at the point.

ACI 318 does not provide rules for designing hanger reinforcement.

A 123-mm-long beam supports a load of P = 40 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.

Shrinkage cracks perpendicular to the span of the one-way design strips will be crossed by flexural reinforcement, which will limit the width of the cracks.

A concrete floor system with a ratio of the longer to the shorter span length that is less than 2 is usually considered a two-way system.
