![AISI S100 / CSA S136 Cold-Formed Steel Design in RFEM 6](/en/webimage/040277/3509688/Cold_formed_AISI_EN.png?mw=512&hash=64fe70077d24767102745523ca11a1880ab1ff6e)
The design of cold-formed steel members according to the AISI S100-16 / CSA S136-16 is available in RFEM 6. Design can be accessed by selecting “AISC 360” or “CSA S16” as the standard in the Steel Design Add-on. “AISI S100” or “CSA S136” is then automatically selected for the cold-formed design.
RFEM applies the Direct Strength Method (DSM) to calculate the elastic buckling load of the member. The Direct Strength Method offers two types of solutions, numerical (Finite Strip Method) and analytical (Specification). The FSM signature curve and buckling shapes can be viewed under Sections.

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.

In the "Import Support Reaction" load wizard, the "Free Loads" object connection type is available in addition to the "Manual" ones. This option saves you the task of manually assigning the support reactions to specific nodes and lines. The support forces of the connected model are applied as free loads in this option.
