FAQ 004917 EN-US
I would like to calculate and design "temporary structures." What do I need for this?
Answer
As a basis for the analysis of temporary structures, both RFEM and RSTAB can be used. For both programs, there are the standards available according to which the steel, aluminum, and lightweight structures can be calculated and designed. If you want to design membrane and cable structures, RFEM is required.
Main Programs RFEM or RSTAB
The main programs RFEM or RSTAB are used to define structures, materials, and actions.
In order to also analyze membrane and cable structures, RFEM is required. When it comes to pure beam structures, it is sufficient to purchase RSTAB. In any case, RFEM is more versatile it can be equipped and extended with the corresponding add-on modules for all materials and structural models.
Available Standards
- RF-/ALUMINUM according to Eurocode 9 (EN 1991-1-1:2007)
- RF-/ALUMINUM ADM according to ADM 2020 (US code)
Add-on modules
- RF-FORM-FINGING / RF-CUTTING-PATTERN (for RFEM only)
Determination of a shape and a cutting pattern for cutting membranes - RWIND Simulation
Complex analysis of any structures in the digital wind tunnel with the transfer of load cases to RFEM or RSTAB for further processing
Dynamic Analysis
Interfaces
- Building Information Modeling (BIM)
An extensive collection of interfaces allows for data exchange with other programs.

SHAPE-THIN determines the effective cross-sections according to EN 1993-1-3 and EN 1993-1-5 for cold-formed sections. You can optionally check the geometric conditions for the applicability of the standard specified in EN 1993‑1‑3, Section 5.2.
The effects of local plate buckling are considered according to the method of reduced widths and the possible buckling of stiffeners (instability) is considered for stiffened sections according to EN 1993-1-3, Section 5.5.
As an option, you can perform an iterative calculation to optimize the effective cross-section.
You can display the effective cross-sections graphically.
