Modeling Downstand Beam in Timber Structures 3: Nonlinear Support Situation

In order to increase the stiffness of a ceiling structure in case of renovation, visible downstand beams are used that are not connected to the ceiling structure. Nonlinear line releases can be used to transfer only the compression forces. If there are tensile forces between the ceiling and the downstand beam, as shown in the figure, the downstand beam does not transfer the stiffness in the overall structure.
