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.
Do you work with the structural components consisting of slabs? In that case, you have to perform the shear force design with the requirements of punching shear design, for example, according to 6.4, EN 1992‑1‑1. In addition to floor slabs, you can also design foundation slabs in this way.
In the Ultimate Configuration for concrete design, you can define the punching design parameters for the selected nodes.
Do you want your structures to remain upright even in wind and snow? Then rely on the load wizards for plate and frame structures. You can now generate wind loads according to EN 1991‑1‑4 and snow loads according to EN 1991‑1‑3 (as well as other international standards). The load cases are generated depending on the roof shape.
Wind loads are also not a problem in your design. You can automatically generate wind loads as member loads or area loads (RFEM) on the following structural components:
- Vertical walls
- Flat roofs
- Monopitch roofs
- Duopitch/troughed roofs
- Vertical walls with duopitch roof
- Vertical walls with flat/monopitch roof

In the "Load Cases & Combinations" dialog box, you have an option to automatically generate load and result combinations as soon as you have selected the corresponding combination expressions. For example, you can also copy or add load cases in a clearly arranged window.
Furthermore, you can manage the load cases and combinations in the tables.
The material library already includes the Canadian types of concrete and reinforcing steel available for design. However, you can always define other materials for the design according to CSA A23.3.
The units used for the reinforced concrete design according to CSA A23.3 are adjusted to the metric system by default.
Utilize all the options of the 'Edit Load Cases and Combinations' dialog box to facilitate your work. Here you can automatically create load and result combinations after selecting the corresponding combination expressions. In this clearly arranged dialog box, you can also e.g. to copy, add, or renumber load cases.
Additionally, control the load cases and combinations in Tables 2.1 – 2.6.

There are load generators available for beam structures, creating snow loads according to ASCE/SEI 7-10. The load cases are generated depending on the roof shape. Another generator creates coating loads (ice). You can save recurring load combinations as templates.
The generated loads can be transferred easily to RFEM/RSTAB in order to superimpose other load cases. All module data is included in the RFEM/RSTAB printout report.
The report contents and the extent of the results can be selected specifically for the individual designs.
After generating the loads, you can check the results in clearly arranged tables. The output includes all information about the generated load cases and loads due to self-weight, wind load, and ice load. All loads are itemized in structural objects and equipment.
The RF-/TOWER Loading add-on module meets the requirements of EN 1991-1-4 / DIN EN 1993-3-1, DIN 1055-4, DIN 4131:1991-11, and DIN V 4131:2008-09. These standards include specifications of dead, wind, maintenance/technician and ice loads (ISO 12494 or DIN 1055-5), as well as variable loads. The standard specifications are preset or available in the libraries.
For the generation of wind loads according to Eurocode, the National Annexes (NA) of the following countries are available:

It is possible to generate individual load situations: You can set the wind pressure, wind direction, or ice loads manually, or import them from tables.
- Consideration of the self-weight of a tower, including equipment
- Wind load distribution to exposed and shaded tower faces, or user-defined distribution
- Determination of wind loads applied to tower and equipment, especially for structures prone to vibration (gust factor)
- Assignment of surface and concentrated loads to platforms
- Optional reduction of total wind load on selected objects
- Determination of ice loads for icing classes G and R with preset ice thickness and ice flag lengths of frost
- Generation of variable load cases with surface and maintenance loads
