A rectangular beam has a cross section of b = 18 in., h = 24 in., and d = 21.5 in. It is reinforced with five No. 5 Grade 60 bars. The concrete strength is 6,400 psi (normal weight). The beam has Grade 60 No. 3 stirrups satisfying ACI 318-14 Sections 9.7.6.2.2 and 9.6.3.3. Determine the strength φMn for this beam.

Determine algebraically whether the function is even, odd, or neither even nor odd. f(x) = -8×3 + 6x (5 points)

For economy, some of the bars can be terminated or cutoff where they are no longer needed.

What is the purpose of using hooks as anchorage?

What is the easiest way to test the bond strength of bars in a laboratory?

The shear failure of a slender beam without stirrups is _______.

What is the easiest way to test the bond strength of bars in a laboratory?

Which of the following are not listed in the text as jobs in OSCM?

Determine the bar-spacing factor, cb, for a simply supported rectangular beam with b = 18 in. and No. 4 stirrups. This beam has three No. 8 bars as longitudinal reinforcement. The clear cover is 1.5 in.

If the depth of the beam varies, the compressive and tensile forces due to flexure will have vertical components.
