What is the easiest way to enter a scissor hinge in RSTAB or RFEM?


In the global coordinate system, special types of hinges are available, such as the scissors hinge. Scissor hinges represent the connection of beam crossings in RSTAB and RFEM.


In the sample file, You have four members connected in one node. Each of the two member pairs transfers moments in its "continuous direction", but they do not transfer any moments to the other pair. Only axial and shear forces are transferred in the node.


A scissor hinge can be implemented in RSTAB or RFEM with a global hinge definition.

In this case, the hinge must be assigned either to members 1 and 2 or to members 3 and 4. The other crossing member pair is modeled as bending-resistant without hinge.

There is also a short video tutorial about "scissor hinges", which you can watch via the link below.
