The beam is simply supported at the left end and fixed at the right end. Under a unform load w, it has the shear and moment diagrams shown above. It has normal weight concrete. The concrete strength is specified to be 4,000 psi and the steel is Grade 60. The amount of reinforcement satisfies the tension-controlled condition. In addition to its own weight, it carries a live of 3 kips/ft. The live load is imposed on the top of the web of the beam. Solve the following parts

The beam is simply supported at the left end and fixed at the right end. Under a unform load
w, it has the shear and moment diagrams shown above. It has normal weight concrete. The
concrete strength is specified to be 4,000 psi and the steel is Grade 60. The amount of
reinforcement satisfies the tension-controlled condition.
In addition to its own weight, it carries a live of 3 kips/ft. The live load is imposed on the top
of the web of the beam. Solve the following parts
Determine the size and spacing of the shear reinforcement (rectangular stirrups)
required for the beam according to ACI 318. Use the same stirrup size and spacing for
all regions where shear reinforcement is required. Determine the region where no
shear reinforcement is required.
