Design a reinforced concrete beam that has a rectangular cross section with a width b = 24 in. The depth h is limited by architectural reasons to 16 in. It has to carry a factored moment Mu = 360 kip- ft. including the self-weight. The design should satisfy ACI 318 for tension controlled members. Use Grade 60 steel and a specified concrete compressive strength = 4,000 psi. Determine the flexural reinforcement for the beam, and use compression steel if needed....
4) A 100 foot long simply-supported bridge girder supports the unfactored loads shown in the figure. The uniformly distributed dead load, wD, includes the self weight of the girder, and is constant along the full beam length. Concentrated live loads, PL, are applied as shown in the figure. a) Draw factored shear force and factored bending moment diagrams in the spaces provided. Show magnitudes at locations A, B, C, D and E on each diagram.(8) PL = 50k PL-50k WD-2.5...

15 points 9. A rectangular concrete beam of width b=24 in. is limited by architectural considerations to a maximum total depth h=16 in. It must carry a total factored load moment Mu 400 k-ft. Design the flexural reinforcement for this member, using compression steel if necessary. Allow 3-in, to the center of the bars from the compression or tension face of the beam. Material strengths are fy=60 ksi and fc=4 ksi. Select reinforcement to provide the needed areas, complete necessary...
