How do shearing stresses on horizontal and vertical planes through an element compare?

A compression-controlled section has a tension-reinforcement area such that when the beam reaches its nominal flexural strength, the net tensile strain in the extreme layer of tensile steel is greater than or equal to 0.005.

Bars of longitudinal reinforcement must extend the full beam length.

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

If a designer wants to increase the moment capacity of a beam, he/she could reduce the amount of tension reinforcement and add compression reinforcement to keep the section compression-controlled.

A beam is singly reinforced with the reinforcement in two rows. The bottom row contains 9 No. 7 bars at a depth of 24 in. The top row contains 5 No. 8 bars at a depth of 20 in. Determine the effective (centroidal) depth, d, of the steel.

A beam has dimensions of b = 20 in., h = 10 in., and d = 7.5 in. and is reinforced with 4 No. 9 bars. The concrete strength is 3,800 psi, and the yield strength of the reinforcement is 60,000 psi. If the depth of the neutral axis is c = 4.371 in., does the reinforcement yield?

Two-way slabs typically have flexural reinforcement in two principal horizontal directions.
