Applying Simply Supported Restraint to a Beam
A simply supported boundary condition can be modeled several ways in Scan&Solve. This document will cover two ways of doing . Both methods will allow for rotation to occur at the ends of the beams. In both cases, a 1.0 kN scalar force was applied to the top face of the I-beam.
Example 1: Restrain neutral axis on ends of beam
The first method will be a slightly less accurate representation, but more simple. This case restrains all displacements along the neutral axis of each end (labelled in blue). The edge restraint was achieved by simply splitting the end faces in Rhino.
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
