Parasol Treehouse at Festival des Cabanes in Rome, Italy

After its creation in 2022, the second edition of the Festival des Cabanes at the Villa Medici in Rome takes place from May 24 to October 1, 2023. Throughout the summer, it offers architects, artists, and people interested in art and culture the opportunity to visit the exhibition in the historic gardens of the Villa Medici. One of the seven cabin projects has benefited from the intervention of Atelier PoCo, a French customer of Dlubal Software, for its design and technical study.

Structure

Le festival 2023 est marqué par la construction de la tour en bois de 13 mètres ayant pour objectif de récupérer l'eau de pluie et de la stocker. La forme de cette tour rappelle celle d'un entonnoir, avec une partie inférieure évasée sur 3,60 m et une partie supérieure élevée d'environ 7 m comprenant trois points d'ailes.

La structure est entièrement réalisée en bois lamellé-collé, offrant à la fois résistance et flexibilité. Pour assurer l'équilibre de la tour, plusieurs tonnes de travertins sont soigneusement disposées à sa base. Des tirants ont été disposés pour contreventer l'ensemble de la structure et garantir sa stabilité.

Étant exposée aux vents, la tour est soumise à des déplacements en tête qui peuvent atteindre plusieurs dizaines de centimètres. Cela exige une conception précise et une attention particulière aux assemblages. Dans ce projet, tous les assemblages sont articulés, permettant à la structure de s'adapter aux mouvements induits par les forces exerçant sur la construction et leur bon transfert jusqu’aux appuis.

Modélisation dans RFEM 6

Le logiciel RFEM 6 a été utilisé pour la modélisation et la descente de charges de la cabane. De plus, il a permis aux concepteurs d'analyser et de simuler le comportement de la structure de la tour, en prenant en compte les charges appliquées avec le module d’analyse de stabilité.

Grâce aux modules spécifiques « Vérification de l’acier » et « Vérification du bois » intégrés dans RFEM 6, les éléments en acier et en bois ont pu être dimensionnés suivant les normes de calcul Eurocode. La possibilité de traiter une structure multi-matériaux dans le programme grâce à l'option du choix de la norme de combinaisons de charges "EN 1990 | Base + Bois", a joué un rôle significatif dans l'optimisation du temps de travail pour ce projet.

La construction de cette cabane en bois représente ainsi un exemple inspirant de l'alliance entre la créativité architecturale et les préoccupations environnementales dans le cadre du festival.

Definition of support conditions in member sets according to EN 1993-1-1
In RF-/STEEL EC3, sets of members are calculated according to the General Method (EN 1993-1-1, Cl. 6.3.4) together with the stability analysis. To do this, it is necessary to determine the correct support conditions for the equivalent structure with four degrees of freedom. In most 3D models today, you can quickly lose track of the location of a set of members in the system.
Limit Value of Torsional Shear Stresses for Cross-Section Design
Very small torsional moments in the members to be designed often prevent certain design formats. In order to neglect them and still perform the designs, you can define a limit value in RF‑/STEEL EC3 from which torsional shear stresses are taken into account.
Activating Weld Design in RF-/STEEL EC3
The RF‑/STEEL EC3 add-on module can perform the design of fillet welds for all parametric, welded cross-sections of the cross-section library. For this, the option must be activated in the detail settings of the module. As an alternative, you can also use a surface model for the design.
Sign Convention for "Load Application of Positive Transverse Loads"
Occasionally, the question arises how to determine the correct load application point of the positive transverse loads in RF-/STEEL EC3 and RF-/STEEL AISC.

Product Features
Feature 002843 | Dimensioning with Result Function

For design objects, you can optionally display sags or extreme results.

Feature 002678 | Connection of Circular Hollow Sections

In the Steel Joints add-on, you can connect circular hollow sections using welds.

It is possible to connect the circular sections to each other or to planar structural components. The fillets of standard and thin-walled sections can also be connected with a weld.

Feature 002672 | Stability and Cross-Section Design for Cold-Formed Sections According to EN 1993-1-3

In the Steel Design add-on, you can perform the stability and cross-section design checks of cold-formed sections according to EN 1993‑1‑3 in compliance with Sections 6.1.2 – 6.1.5 and 6.1.8 – 6.1.10.

Feature 002667 | Classification of Steel Joints by Stiffness

In the Steel Joints add-on, you can classify the joint stiffnesses.

In addition to the initial stiffness, the table also shows the limit values for hinged and rigid connections for the selected internal forces N, My, and/or Mz. The resulting classification is then displayed in tables as "hinged", "semi-rigid", or "rigid".

Frequently Asked Questions (FAQ)
I do not want to design a cross-section in the RF‑/STEEL EC3 add-on module. Can I remove this cross-section from the selection quickly?
I am designing a set of members 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?
Why are the equivalent member design checks grayed out in the Stability tab when activating the plastic design using the partial internal force method (RF‑/STEEL Plasticity)?
How can I change the details and the National Annex in the STEEL EC3 add-on module using the COM interface?
Ich möchte einen langen Fachwerkobergurt auf Stabilität untersuchen. Wie ist hier am besten vorzugehen?
Which cross-sections can I design with the "RF‑/STEEL Cold-Formed Sections" add-on module?
