Show your answers in two plots of Vc along the span. Note ACI 318-11, 11.1.3.1. Also graph Vn,req along the span in each plot. On each plot, show the regions within which no shear reinforcement is required, the regions in which only minimum shear reinforcement is required, and the regions in which shear reinforcement must be designed. 2) Using the two excess shear diagrams you have just constructed, design transverse reinforcement for the beam a) Use Vc = 2√ √fe'bwd and a uniform stirrup spacing. Do not reduce shear to the value a distance d from the support. b) Use Vc = 2√fe'bwd and a uniform stirrup spacing. Reduce shear to the value a distance d from the support. c) Use Vc = 2√√fe'bwd and a variable stirrup spacing, omitting shear reinforcement when permitted. Reduce shear to the value a distance d from the support. d) Use Vc = (1.9√fe + 25000p ) ≤ 3.5√fe'bwd and a variable stirrup spacing. Reduce shear to the value a distance d from the support.
