How do you generate the shear and moment diagrams?
Depending of the type and magnitude of the applied loads, the shears, moments, and reactions will vary along the beam. Since a continuous beam is a statically indeterminate structure, it cannot be resolved just with the static equilibrium equations. Many analytical and numerical methods have been developed to find the reactions, shears and moments along the beam.
Whatever method is used, at the end of this analysis phase the shear and moment diagrams will be developed, showing the variation of these internal forces, and therefore the required strengths, along the beam. ASDIP CONCRETE accurately generates the shear and moment diagrams, per load combination, as shown below.
