FAQ 004320 EN-US

When opening an RSTAB 8 file including scissor hinges in RFEM 5, I get an error message saying that the scissor hinges could not be imported correctly. What is the reason?


Please check the definition of the scissor hinges in the RSTAB 8 file.

To properly consider the function of the scissor hinge, the scissor hinge of the same type must be specified on the member ends of both members ‘touching’ at a node. If this is not the case, you receive the described error message.

Figure 01 - Note Regarding Incorrectly Defined Scissor Hinges

If you have got this error message displayed when opening an RSTAB 8 file in RFEM 5, this may lead to problems in the calculation, for example, the structure becomes unstable due to incorrect hinge definition (already in RSTAB 8).

The problem should, therefore, be adjusted either already in the RSTAB 8 file or the RFEM model after import.
