Simply supported beams loaded with only gravity loads develop tension cracks along the bottom of the beam.

A beam is singly reinforced with the reinforcement in two rows. The bottom row contains 9 No. 5 bars at a depth of 14 in. The top row contains 6 No. 8 bars at a depth of 8 in. Determine the effective (centroidal) depth, d, of the steel.

Generally, slab thickness is based on deflection limits, and then the design is checked for shear and flexure.

Cantilever beams loaded with only gravity loads require longitudinal reinforcement along the top of the beam.

Additional concrete cover helps to accelerate reinforcement corrosion.

Flexural stiffness is inversely related to span length. Therefore, a lower percentage of the load applied to floor panels is carried in the short span direction as compared to the long span direction.

Determine β1 given that f’c = 9,400 psi.

You are considering a beam design that has dimensions of b = 14 in., h = 24 in., and d = 21.5 in. The beam is singly reinforced with all of the reinforcement in a single row. The concrete strength is 8,800 psi, and the yield strength of the reinforcement is 60,000 psi. What cross-sectional area of reinforcement is needed to achieve a strain in the reinforcement of 0.0075?

Two-way slabs typically have flexural reinforcement in two principal horizontal directions.

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 4 No. 8 bars on the tension side. The concrete strength is 2,500 psi, and the yield strength of the reinforcement is 60,000 psi. If the depth of the neutral axis is c = 6.268 in., determine the force in the compression reinforcement, Cs.
