Where there are several layers of reinforcement, a continuous horizontal opening large enough for the concrete vibrator to pass through should be provided.

Stirrups are instrumental in preventing inclined cracks from forming.

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?

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

Assuming Vs does not exceed 4sqrt(f’c)bwd, the maximum spacing for vertical stirrups in the following beam is _____. Let b1 = 28 in., b2 = 14 in., d = 49 in., h1 = 4 in., h2 = 42 in., h3 = 8 in., and t = 7 in. There are six No. 6 longitudinal tension bars and No. 4 stirrups at 11 in. o.c.

The traditional theory for shear stress assumes homogeneous, elastic, and uncracked beams.

Compute φVn for the cross section shown. Assume f’c = 5,500 psi, fyt = 60,000 psi, b1 = 26 in., b2 = 10 in., d = 22 in., h1 = 4 in., h2 = 14 in., h3 = 9 in., t = 6 in., and that there are six No. 6 longitudinal tension bars and No. 4 stirrups at 12 in. o.c.

Compute φVn for the cross section shown. Assume f’c = 5,000 psi, fyt = 40,000 psi, d = 28 in., w = 22.5 in., t = 4 in., and that there are four No. 7 longitudinal tension bars and No. 3 stirrups at 10 in. o.c.

Compute φVn for the cross section shown. Assume f’c = 4,000 psi, fyt = 60,000 psi, b = 10 in., d = 26 in., and that there are four No. 7 longitudinal tension bars and No. 4 stirrups at 8 in. o.c.
