A simply supported beam with dimensions of b = 16 in., h = 30 in., d = 27.5 in., and L = 17 ft supports a uniform service (unfactored) dead load consisting of its own weight plus 1.1 kips/ft and a uniform service (unfactored) live load of 1.1 kips/ft. The concrete is normal-weight concrete. Determine the moment due to the factored loads, Mu.      

A beam is singly reinforced with the reinforcement in two rows. The bottom row contains 8 No. 6 bars at a depth of 18 in. The top row contains 6 No. 7 bars at a depth of 14 in. Determine the effective (centroidal) depth, d, of the steel.

According to the theory of flexure for reinforced concrete, the strain in the reinforcement is _______ the strain in the concrete at the same level.

The elastic beam theory is used in the design of reinforced concrete beams.

A tension-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.

Cantilever beams loaded with only gravity loads develop positive bending moments throughout the span.

Elasticity is the name given to a sample’s ability to deform beyond its yield point without a significant loss of strength.

Flexural stiffness is inversely related to span length. Therefore, slab panels are much stiffer in their shorter span direction than in the longer span direction.

Determine As,min for the following beam given that f’c = 8,750 psi and fy = 60,000 psi.

Concrete forms should generally be chosen to allow for minimum reuse of the forms.
