The Mueller-Breslau principle is not helpful for structures that will be analyzed via computer software packages.

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 3,100 psi, and the yield strength of the reinforcement is 60,000 psi. If the depth of the neutral axis is c = 5.205 in., determine the strain in the compression reinforcement, ε’s.

Which of the following best describes a smeared-crack model?

A simply-supported beam has a 1 kip/ft uniformly-distributed load over the entire 8-ft span. What is the magnitude of the maximum shear force in the beam?

In designing for shear, one must ensure that the flexural strength equals or exceeds the shear strength at all points in the beam.

As the size of coarse aggregate increases, the roughness of the crack increases. This allows higher shear stresses to be transferred across the crack.

The use of compression reinforcement permits the use of more tension reinforcement to decrease the strength of a given beam section while keeping the section compression-controlled.

If φVc = 50 kip and Vu = 58 kip, are stirrups required?

A combination of horizontal and vertical reinforcement is used to restrain cracks from opening too wide.

Which of the following is not a common type of splice?
