The structural analysis program RFEM is the basis of a modular software system. The main program RFEM is used to define structures, materials, and loads for planar and spatial structural systems consisting of plates, walls, shells and members. The program also allows you to create combined structures as well as model solid and contact elements.
The structural beam analysis program RSTAB determines internal forces, deformations and support reactions. For designs, there are various add-on modules considering the material and standard-specific circumstances. Due to the modular software system, it is possible to use the program package that perfectly meets your individual needs.
Here you can find numerous add-on modules for the design of joints in steel and timber structures.
Customer Project with Connection Design
The historical building of Théâtre Marigny had to undergo renovation due to its serious defects of the roof structure which led to its closure in 2013.
The metastable equilibrium resulted from unreliable planning which did not consider the effects of assymetrical load and the suspended ceiling on the roof structure during construction in 1925.

The member hinge nonlinearities "Scaffolding - N phiy / phiz" and "Scaffolding Diagram" enable the mechanical simulation of a tube joint with an inner stub between two member elements.
The equivalent model transfers the bending moment via the overpressed outer pipe and after positive locking additionally via the inner stub, depending on the compression state at the member end.
