Modeling | Loading RFEM

When transferring the bearing loads with the help of the function "Take over bearing reactions as load", I noticed differences in the load sums.

Answer

If loads are transferred from one model to another, then the loads to be transferred are exported as "free loads" with fixed coordinates. For each of the free loads, you can specify on which surface it should act. As a rule, load transfer activates "all". This means that all surfaces that penetrate these individual loads are loaded. So it can happen that some surfaces are loaded unintentionally. This results in a larger load sum in the model.

It is therefore recommended to use the function "Take over bearing reactions as load" specify on which areas the load to be imported may be applied (see Figure 1). In the free loads themselves, the surfaces to which the load is to act may also be adjusted (see Figure 2).
