Stadium La Montura, Chile
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.

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.

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.

- 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?
- How is the automatic creation of c/t-parts carried out?
- I design a set of members by using the equivalent member method in RF‑/STEEL EC3, but the calculation fails. The system is unstable, delivering the message "Non-designable - ER055) Zero value of the critical moment on the segment."What could be the reason?
- How is it possible to make factorized combinations of a dead load in the context of form‑finding?
- My aim is to mesh a circular hole plate in a mapped way. Is such a meshing possible in RFEM?
- Can the reduction of strength in the heat affected zone (HAZ) be taken into account in the RF-/ALUMINUM add-on module?
- The design ratio of the cross-section check is different for the RF‑/STEEL and RF‑/STEEL EC3 add-on module. What is the reason?
- What is the meaning of the warning message ER061) Minimum amplifier of design loads <1?
