If a beam is supported by a girder of essentially the same depth, the compression fans that form in the supported beam tend to push the bottom off the supporting beam.

Compute φVn for the cross section shown. Assume f’c = 8,000 psi, fyt = 60,000 psi, b = 15 in., d = 23 in., and that there are four No. 6 longitudinal tension bars and No. 5 stirrups at 11 in. o.c.

At a point subjected to plane stress, the stresses are σx = 70 MPa, σy = –60 MPa, and τxy = 10 MPa. Determine the angle θp corresponding to the orientation of the principal planes at the point.

In a mechanical splice, the force in one bar is transferred to the concrete, which transfers it to the adjacent bar.

_______ cracks occur first due to flexural stresses and start at the bottom of the beam.

To ensure safety in building design, standards recommend that shear strength be _______ flexural strength at all points on a beam.

To help prevent excessively wide inclined cracks, the textbook author recommends the use of _______.

A simply-supported beam has a 5 kip/ft uniformly-distributed load over the left half of its 9-ft span. What is the magnitude of the maximum shear force in the beam?

Inclined stirrups are an ineffective solution for resisting seismic loads.

A simply-supported beam has a 2 kip/ft uniformly-distributed load over the entire 8-ft span. What is the magnitude of the maximum shear force in the beam?
