(50 pts) The simply supported beam shown in the figure below is being designed for shear. #3 stirrups (Grade 40) are to be used. a. Draw the factored shear envelope for Vu (20 pts) b. Determine the resistance to shear provided by the concrete. Are there any regions where no shear stirrups are required? (15 pts) Design the stirrup spacing required to resist the maximum shear (15 pts)с. Design the stirrup spacing required to resist the maximum shear
