Tensile Structure for "International Circus Festival of Italy"
For twenty years, the Circus Festival in Latina has been thrilling audiences with the world’s most talented artists. The International Circus Festival of Italy, founded by Giulio Montico and operated by the Montico family, has been recognized globally since the first performance. The circus tent built in Latina has made it possible to appreciate the quality of the many artists performing there.

Structural DesignThe membrane-covered cable structure is a temporary structure which includes eight masts as well as poles and steel cables. The floor plan is 60 x 36 m with a covered area of 2146 m2.
The structure is covered with a highly resistant polyester with polyvinyl chloride coating fabric, a special fabrication for textile structures. The middle masts are varying pipe steel cross-sections with 245 cm x 8 cm dimensions from the ground up to a height of 8 m and 225 cm x12 cm dimensions to the remaining top of the tent. The poles are 76 cm x 3 cm and 89 cm x 3 cm spaced at a maximum distance of 2 m. The total membrane height is 13.2 m.

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.

- When calculating a cable using the STEEL EC3 add‑on module, he error message "Incorrect characteristic stresses for material No. 1! Please correct this in Table 1.2." appears.
- Are the effective length coefficients in the add-on modules for the aluminum and steel design automatically determined from the model or do I have to make adjustments?
- I design a cross-section created in the SHAPE‑THIN program by using the RF‑STEEL EC3 add-on module, but the program shows the error message "ER006 Invalid type of c/t-part for cross-section of type General." What can I do?
Is it possible to calculate American steel cross-sections?
- Where do I find the setting to specify the entered structural component as a "wall" or "slab"?
- How can I quickly model a chimney with reinforcement rings and stiffeners?
- How can I model and design general bolted connections with the surface and solid elements in RFEM?
- I get the message "Existing torsion -> no stability design possible." Why does this appear and what can I do?
- I design an asymmetric cross-section and get the message: "Non-designable: ER051) Moment about z‑axis on asymmetric cross-section, taper or set of members." Why?
- How can I consider holes in steel members?
