The height of available chairs may control the chosen slab thickness.

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.

A 123-mm-long beam supports a load of P = 30 N at midspan. The cross section is rectangular with width b = 27 mm and height h = 60 mm. Determine the magnitude of the horizontal shear stress at the centroid of the cross section.

Is it more important to put transverse reinforcement at the ends of a splice or in the middle?

Shear stresses will exist in those parts of a beam where the moment changes from section to section.

Assuming Vs does not exceed 4sqrt(f’c)bwd, the maximum spacing for vertical stirrups in the following beam is _____. Let b1 = 23 in., b2 = 11 in., d1 = 6 in., and d2 = 53 in. There are three No. 6 longitudinal tension bars and No. 4 stirrups at 10 in. o.c.

Compute φVn for the cross section shown. Assume f’c = 3,500 psi, fyt = 60,000 psi, d = 30 in., w = 20.5 in., t = 6 in., and that there are four No. 6 longitudinal tension bars and No. 5 stirrups at 9 in. o.c.

When a beam is supported by a girder or other beam of essentially the same depth, hanger reinforcement should be provided in the joint.

Assuming Vs does not exceed 4sqrt(f’c)bwd, the maximum spacing for vertical stirrups in the following beam is _____. Let b = 15 in. and d = 43 in. There are four No. 9 longitudinal tension bars and No. 4 stirrups at 7 in. o.c.
