Name: Date: 2. (+35) Design a typical interior tension-reinforced T-beam to resist positive moment. Beam dimension is given. The service loads are 150 psf dead load (doesn't include the beam weight) and 350 psf live load. The beam is on a simple span of 20 ft. Use f:=4000 psi for strength concrete and fy=60000 psi for steel reinforcement. 8-0* (typ.)

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...

1. A simply supported rectangular concrete beam has a clear span of 6m has a width of 400mm and has an effective depth of 625mm. The beam supports a total factored load of 168kN/m which includes the weight of the beam. Use fc’=28MPa, fy=414MPa. Use normal weight of concrete with 1.0. Determine approximately the total number of stirrups needed for the beam. 2. A rectangular beam reinforced for tension only has b=200mm and d=350mm. The tension steel area provided is...
