- | =====Applying Simply Supported Restraint to a Beam===== | ||
- | A simply supported boundary condition can be modeled several ways in Scan& | ||
- | ====Example 1: Restrain neutral axis on ends of beam==== | ||
- | The first method | ||
- | |||
- | So while this method allows for rotation about the end, it does not allow for the beam to stretch (or roll, in terms of a rolling support) at the ends. | ||

- | ====Example 2: Apply equilibrium loads and restrain edge in middle of beam==== | ||
- | The second method relies on the symmetry of the beam loading. | ||
- | |||
- | For this loading, the best choice to restrain the model is where the slope of deflection will be zero. In this case, zero bending slope occurs at the mid-point of the beam. This example restrains the midpoint edge at the bottom, although the edge at the top is also a valid choice. | ||

- | |||
- | The static equilibrium loading produces the same bending shape and almost the same peak bending stress as the first case. In addition, the peak Z-direction deflections are also quite similar. | ||
