Determine As,min for the following beam given that f’c = 6,000 psi and fy = 60,000 psi.

A beam has dimensions of b = 14 in., h = 26 in., d’ = 2.5 in., and d = 23.5 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. For the results given below, determine the strength Mn for this beam.a = 4.75 in. (depth of concrete stress block)Cc = 207.2 kips (compressive force in concrete)Cs = 29.8 kips (compressive force in steel)T = 237.0 kips (tensile force in steel)

ACI Code Section 22.2.2.1 specifies a limiting compressive strain, εcu, equal to _____.

A beam has dimensions of b = 18 in., h = 10 in., and d = 7.5 in. and is reinforced with 5 No. 6 bars. The concrete strength is 3,500 psi, and the yield strength of the reinforcement is 60,000 psi. If the depth of the neutral axis is c = 2.9 in., does the reinforcement yield?

Beams that span from column to column are commonly referred to as girders.

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

Which symbol represents the assumed maximum useable compression strain in concrete?

A beam has dimensions of b = 14 in., h = 26 in., and d = 23.5 in. and is reinforced with 3 No. 8 bars. The concrete strength is 6,400 psi, and the yield strength of the reinforcement is 60,000 psi. Determine the nominal moment capacity, Mn, of the beam.
