Answer:
Both RFEM and RSTAB are available for the structural analysis and design of temporary structures, such as carousels, roller coasters, stages, or grandstands. There are add-ons available for both main programs that you can use to design steel, aluminum and lightweight structures according to various standards. If you also want to analyze membrane and cable structures, RFEM is your tool of choice.
Main Programs RFEM and RSTAB
The main programs RFEM and RSTAB are used to define the model with its properties and actions. RFEM proves to be the more versatile option, as it can be used to analyze structures with surface components, such as membranes, in addition to pure member structures.
Available Standards
For the design of steel beam and cable structures, the following standards are available:
- EN 1993 (Eurocode 3)
- BS 5950 (British standard)
- AISC 360 (US standard)
- SIA 263 (Swiss standard)
- IS 800 (Indian standard)
- GB 50017 (Chinese standard)
- CSA S16 (Canadian standard)
- AS 4100 (Australian standard)
- NBR 8800 (Brazilian standard)
- SP 16.13330 (Russian standard)
Aluminum structures can be designed according to the following standards:
- EN 1999 (Eurocode 9)
- ADM (US standard)
- GB 50429 (Chinese standard)
Analysis and Design Add-ons
Design add-ons supplement the functionality of the main programs. The Steel Design and Aluminum Design add-ons allow you to perform the ultimate and serviceability limit state design, as well as the stability analysis according to the standards listed above.
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. On the other hand, you can use the RWIND program to perform simulations in the digital wind tunnel for complex structures and to transfer the generated wind loads to RFEM.
Dynamic Analysis
If you need to perform a seismic or vibration analysis, the corresponding Dynamic Analysis add-ons are the perfect tools for determining natural frequencies and mode shapes, or for the analysis of external excitations.
