Eccentric Nodal Loads
Tips & Tricks
There are two ways to specify eccentric nodal loads in RF‑/FE‑LTB. First, the nodal load has to be applied in the right direction. Then, you can assign either the resulting torsional moment or the eccentricity.
For the selection, the load reference is crucial. When entering the torsional moment, the load acts independently of the deformation. In detail, this means that the load remains constant when rotating the member about its axis.
The more usual case of dividing the load by the rotation is created by using the defined eccentricity. For example, if there is an eccentricity for a load in the local z‑direction, the member torsion causes the resulting torsional moment to be partially redistributed in the local y‑direction so the torsional moment failure is smaller than in the first case.
