Most concrete design codes specify a maximum usable compressive strain at which the nominal moment strength of the section is to be calculated. For ACI 318, this maximum usable strain value is 0.003.

Which symbol represents the stress in the tension reinforcement of a reinforced concrete beam?

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 3,700 psi, and the yield strength of the reinforcement is 60,000 psi. If the depth of the neutral axis is c = 5.588 in., determine the strain in the compression reinforcement, ε’s.

In a one-way slab, the slab strips used for analysis span the long direction of the panel.

Alternate span loading is the common loading pattern for determining maximum shear at the supports between the loaded spans due to dead load.

Determine As,min for the following beam given that f’c = 5,750 psi and fy = 60,000 psi.

The φ for a singly-reinforced beam with an εs ≥ 0.005 would be _____.

Determine β1 given that f’c = 8,500 psi.

A beam has dimensions of b = 16 in., h = 22 in., and d = 19.5 in. and is reinforced with 2 No. 5 bars. The concrete strength is 7,300 psi, and the yield strength of the reinforcement is 60,000 psi. Determine the strength Mn for this beam.

You are considering a beam design that has dimensions of b = 16 in., h = 22 in., and d = 19.5 in. The beam is singly reinforced with all of the reinforcement in a single row. The concrete strength is 2,500 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?
