When modeling surfaces supported on members or beams in RFEM 6, modeling errors of the load transfer may easily occur. When modeling a line support on the member line where the surface is supported, the load of the surface is transferred directly to the support, but the stiffness of the member or the beam is not taken into account, nor is the beam loaded and designed correctly.If you want to model the member or the beam as a support, it is important to use a member support. You can select it in the Types for Members category of the Navigator – Data.The following video uses a very simple example to show you how the different modeling affects the force distributions. This effect becomes all the more governing in the case of more complex models.
