Oxigeno in San Francisco de Heredia, Costa Rica
Customer Project
A unique project called "Oxigeno" is currently under construction in San Francisco de Heredia, San José, Costa Rica. The recreational and commercial space, which measures almost 1,345,489 ft², offers the visitor a relaxing shopping atmosphere in harmony with nature. Among other things, 200 trees were planted on the site. The main food court is covered with a 17,222 ft² ETFE cushion as a roof, currently the biggest in the world.

Model
Dlubal customer z3rch used RFEM and RF-FORM-FINDING for the form-finding and the calculation of the structure, including the cable web structure and the membranes.
Structure of ETFE Roof
The roof, with a diameter of 148 ft, consists of an ETFE foil, which is supported by a cable web. At the edge, square hollow sections form two circulating rings, which are supported on the customer's structure.
A security system to protect against the formation of water pockets is used for this project; it was developed by the company 3dtex. No plastic tube is inserted here inside the cushion. This system will ensure higher safety against the formation of water pockets on one hand and a clear, elegant architectural design of the structure on the other hand.
The ETFE cushion is the first in the city of San Francisco de Heredia and the biggest in the world.

CSA S16:19 Stability Considerations and the New Annex O.2
The CSA S16:19 Stability Effects in Elastic Analysis method in Annex O.2 is an alternative option to the Simplified Stability Analysis Method in Clause 8.4.3. This article will describe the requirements of Annex O.2 and application in RFEM 6.
- 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?
- The load distribution on my members looks different when using the Load Transfer surface vs. the Load Wizards. What is the reason?
- My beam has a continuous lateral support and therefore lateral torsional buckling (LTB) is not a concern. How do I define the effective length?
- I received an error message “Surface of incompatible type... (Surface in upper plane of building story must be of ‘Load transfer’ type)” when running the calculation. What is the reason?
