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 1) Briefly explain the shear-lag phenomenon and how it affects the flexural behavior of a flanged beam. How is this considered in design according to ACI 318? ) What specification is used in ACI 318 to control crack width under flexure?

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
a) Briefly explain the shear-lag phenomenon and how it affects the flexural behavior
of a flanged beam. How is this considered in design according to ACI 318?
b) What specification is used in ACI 318 to control crack width under flexure?
