Dlubal Software for Structural Analysis and Design of Aluminium Structures
A roof made of steel and fabric membranes was designed for the football stadium in San Bernardo, a city in the south of Santiago. The elegant, curved design in lightweight construction now also covers the standing area.

Model
Structure
The main structural elements, such as arches and bracing curve members, are made of steel and have a total span of ~ 241.1 ft between the concrete pile supports. The cladding system consists of a series of tensioned fabric membranes with a width of ~ 10.5 ft, which span a length of ~ 23 to 42.7 ft and are surrounded by corner cables.
This roofing system creates a transparent picture of the roof while protecting spectators from the effects of the weather.

Generation of Snow Loads in RFEM 6 According to ASCE/SEI 7-16 and EN 1991-1-3
The effects due to snow load are described in the American standard ASCE/SEI 7-16 and in Eurocode 1, Parts 1 through 3. These standards are implemented in the new RFEM 6 program and the Snow Load Wizard, which serves to facilitate the application of snow loads. In addition to this, the most recent generation of the program allows the construction site to be specified on a digital map, thus allowing the snow load zone to be imported automatically. These data are, in turn, used by the Load Wizard to simulate the effects due to the snow load.

Steel Joints | Stability Analysis Software
For the joint components, it is possible to check whether the stability failure is relevant (requires the Structure Stability add-on for RFEM 6 / RSTAB 9).
In this case, the critical load factor for all analyzed load combinations and the selected number of mode shapes is calculated for the connection model. The smallest critical load factor is compared with the limit value 15 from the standard EN 1993‑1‑1, Clause 5. Furthermore, a user-defined adjustment of the limit value is possible. Moreover, the corresponding mode shapes are displayed graphically as the result of the stability analysis.
For the stability analysis, an adapted surface model is used to specifically recognize the local buckling shapes. The model of the stability analysis, including the results, can also be saved and used as a separate model file.
- Which Dlubal Software programs are required to calculate membrane and tensile structures?
- I would like to analyze cable and tensile structures. Is it possible to use RFEM or RSTAB for this?
- Is it possible to display the deformation analysis of a surface (limit 0.5‰)?
- How do I perform stability analysis to determine the critical load factor in RFEM 6?
- How can I optimize cross-sections within the steel design?
- Why do the results in a modal analysis differ between the initial prestress and the surface load?
- 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?
- Is it also possible to use RF‑/TOWER Loading without the other TOWER add-on modules?
- Although I have modeled two identical structural systems, I obtain a different shape. Why?
