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...
2. Design a rectangular section for the beam below with the loads shown. The self weight of the beam is not included in the dead load of the beam and should be considered in the design. Show a sketch of your cross section, including bar sizes, arrangement, and spacing. Assume concrete weighs 150 lb/ft.
