Chapter 3: Reinforced Concrete Slabs and Beams, Part 4
This application calculates the spacing for shear reinforcement of a concrete beam supporting a uniformly distributed load. The application uses the strength design method of ACI 318-89, and calculates shear strength of the concrete using the simplified method of ACI Section 11-3, Eq. (11-3). The required input includes strength of concrete, strength of reinforcement, unit weight of concrete, length of beam between the face of support and the point where shear passes through zero, uniformly distributed factored load, effective beam depth, beam web width, flange thickness and cross sectional area of the ties or stirrups.
