Figure 2 shows a simply supported beam and the cross section at mid span. The beam supports a uniform service (unfactored) dead load consisting of its own weight plus 1.4 kips/ft and a uniform service (unfactored) live load of 1.5 kips/ft. The concrete strength is 3500 psi, and the yield strength of the reinforcement is 60,000 psi. The concrete is normal-weight concrete. For the midspan section shown in Figure 2, compute фМп and show that it exceeds Mu. WD 1.4...
