A beam has dimensions of b = 18 in., h = 30 in., and d = 27.5 in. and is reinforced with 3 No. 7 bars. The concrete strength is 4,600 psi, and the yield strength of the reinforcement is 60,000 psi. If the depth to the neutral surface is c = 1.871374 in., determine the strain in the reinforcement.

One of the three basic assumptions in the theory of flexure for reinforce concrete is that sections perpendicular to the axis of bending that are plane before bending remains plane after bending.

You are considering a beam design that has dimensions of b = 16 in., h = 26 in., and d = 23.5 in. The beam is singly reinforced with all of the reinforcement in a single row. The concrete strength is 3,400 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?

A beam has dimensions of b = 18 in., h = 30 in., and d = 27.5 in. and is reinforced with 5 No. 7 bars. The concrete strength is 10,000 psi, and the yield strength of the reinforcement is 60,000 psi. Assuming the reinforcement has yielded, determine the depth to the neutral axis, c.

A beam has dimensions of b = 18 in., h = 30 in., and d = 27.5 in. and is reinforced with 2 No. 6 bars. The concrete strength is 3,100 psi, and the yield strength of the reinforcement is 60,000 psi. Assuming the reinforcement has yielded, determine the depth to the neutral axis, c.

Determine As,min for the following beam given that f’c = 7,250 psi and fy = 60,000 psi.

A beam has dimensions of b = 14 in., h = 28 in., and d = 25.5 in. and is reinforced with 4 No. 5 bars. The concrete strength is 4,600 psi, and the yield strength of the reinforcement is 60,000 psi. If the depth to the neutral surface is c = 1.657503 in., determine the strain in the reinforcement.

A beam has dimensions of b = 18 in., h = 28 in., and d = 25.5 in. and is reinforced with 2 No. 6 bars. The concrete strength is 3,400 psi, and the yield strength of the reinforcement is 60,000 psi. Assuming the reinforcement has yielded, determine the tensile force T in the reinforcement.

A beam has dimensions of b = 16 in., h = 28 in., and d = 25.5 in. and is reinforced with 5 No. 8 bars. The concrete strength is 4,900 psi, and the yield strength of the reinforcement is 60,000 psi. Assuming the reinforcement has yielded, determine the tensile force T in the reinforcement.
