Reinforcing steel bars in slabs are rarely smaller than a #4 bar for which of the following reasons? Check
all that apply.
Workers can permanently bend smaller bars prior to pouring the concrete
Smaller bars cannot provide sufficient flexural strength
Smaller bars cannot provide sufficient shear strength
Smaller bars lead to excessive deflections after the concrete has set - correct answer ✔Workers can
permanently bend smaller bars prior to pouring the concrete
How much "steel per foot" is there in a slab with #4 bars (area=0.2 in2) spaced 8 inches on center? -
correct answer ✔0.3 in^2
The thickness of one-way slabs is usually controlled by which of the following criteria?
Flexural strength
Shear strength
Deflections - correct answer ✔Deflections
As the spacing, s, between transverse reinforcing steel "stirrups" in an RC beam decreases, the shear
strength of the beam will: Increase or Decrease - correct answer ✔Increase
Select all true statements regarding the design shear strength of RC beams.
The shear strength is comprised of concrete and steel contributions
Shear reinforcement is not required under certain conditions
Shear reinforcement is always required because plain concrete has zero shear strength
