RF-/ALUMINUM ADM Add-on Module for RFEM/RSTAB
Design of Aluminium Members According to American Standards ADM 2020
The RF-/ALUMINUM ADM add-on module performs the ultimate and the serviceability limit state designs of members and sets of members according to the American standards ADM 2010, ADM 2015 and ADM 2020. It includes the analysis methods:
- Load and Resistance Factor Design (LRFD)
- Allowable Stress Design (ASD)
- Design of members and sets of members for tension, compression, bending, shear, torsion, and combined internal forces
- Stability analysis of buckling, torsional-flexural and lateral-torsional buckling
- Automatic determination of effective radius of gyration by special integrated FEA software (eigenvalue analysis) for general loading and support conditions
- Alternative analytical calculation of effective radius of gyration for standard situations
- Optional application of discrete lateral supports to beams
- Definition of nodal supports for sets of members
- Serviceability limit state design (deflection)
- Cross-section optimization
- Wide range of cross-sections available, for example I-, C-, and T‑sections as well as angles, rectangular and circular hollow sections, round bars, and many other
- Detailed result documentation including references to design equations of the used standard
- Various filter and sorting options of results including result lists by member, cross-sections, x-location, or by load case, load and result combination
- Result table of member slenderness and governing internal forces
- Metric and imperial units
First, it is necessary to decide whether to perform design according to ASD or LRFD. Then, you can enter the load cases, load combinations, and result combinations to be designed. Load combinations according to ASCE 7 can be generated either manually or automatically in RFEM/RSTAB.
Further specifications include presetting of lateral intermediate supports, effective lengths, and other standard-specific design parameters. When using continuous members, it is possible to define individual support conditions and eccentricities of each intermediate node of single members. A special FEA tool determines effective radii of gyration required for the stability analysis in the case of these situations.
The first result window shows the maximum design ratios with the corresponding design of each designed load case (load combination / result combination).
The other result windows list all detailed results sorted by specific subject in extendable tree menus. All intermediate results along a member can be displayed at any location. In this way, you can easily retrace how the module has performed the individual designs.
The complete data from the module is part of the RFEM/RSTAB printout report.

The Aluminum Design Manual (ADM) 2020 was released in February 2020. The ADM 2020 gives guidance for both the allowable strength design (ASD) and load and resistance factor design (LRFD) for aluminum members to ensure reliability and safety for all aluminum structures.
Compared to the RF-/ALUMINUM add-on module (RFEM 5/RSTAB 8), the following new features have been added to the Aluminum Design add-on for RFEM 6/RSTAB 9:
- In addition to Eurocode 9, the US standard ADM 2020 is integrated
- Consideration of the stabilizing effect of purlins and sheets by rotational restraints and shear panels
- Graphical display of the results in the gross section
- Output of the used design check formulas (including a reference to the used equation from the standard)
- Where can I find the materials for the corresponding National Annexes in RFEM 6 and RSTAB 9?
- How do I apply wind load on members of open structures?
- I encountered a sharing violation while importing a dxf file into SHAPE‑THIN. What is the issue?
- How is the automatic creation of c/t-parts carried out?
- My aim is to mesh a circular hole plate in a mapped way. Is such a meshing possible in RFEM?
- Is it possible to consider the reduction of strength in the heat affected zone (HAZ) in the RF‑/ALUMINUM add-on module?
- SHAPE‑THIN calculates a very small shear area. Why?
- My member is oriented at the inclination of principal axis when I import from SHAPE-THIN to a 2D RFEM model. How do I fix this?
- How can I get the member end forces to design the connections?
- I would like to design an aluminum or lightweight structure. Is it possible to use RFEM or RSTAB for this?
