Answer:
Both RFEM and RSTAB provide solution: There are numerous European and international standards as well as add-ons available for both programs that can facilitate your daily work in structural design of aluminum and lightweight structures.
Main Programs RFEM and RSTAB
The main programs RFEM and RSTAB are used to define the model with its properties and actions. In addition to spatial beam structures, such as scaffolding or frame structures, you can also model membrane structures with RFEM. Thus, RFEM is the more versatile variant—especially if you work in other areas, such as solid construction.
Available Standards
- EN 1999 (Eurocode 9)
- ADM (US standard)
- GB 50429 (Chinese standard)
Add-ons for Aluminum and Lightweight Structure
Design add-ons supplement the functionality of the main programs. The Aluminum Design add-ons allow you to perform the ultimate and serviceability limit state design checks, as well as the stability analysis according to the standards listed above. The Torsional Warping (7 DOF) analysis add-on allows for lateral-torsional buckling design with up to seven degrees of freedom.
The design checks can be carried out for a large number of standardized and parameterized cross-sections. Lightweight structures often includes special cross-sections, such as extruded sections. You can define it with the RSECTION program and use it for the design in RFEM or RSTAB.
In the case of membrane and cable structures, the Form-Finding add-on facilitates your task to determine the shape of member and surface models subjected to axial forces.
