Sports Venue in Donzère, France
To meet the needs of its citizens, the city of Donzère decided to build a sports hall on a large triangular island, at the foot of the historic village. The new structure, dedicated to local schools and clubs, created the opportunity for sports event practice and competitions.

The building is divided into two parts. The first part houses the gymnasium while the second includes the fitness studio, dojo ring, and administrative offices.
Two large truss beams with a wooden lattice, also known as mashrabiya style, are placed at the height of the vertical window panels, allowing for natural light throughout the gymnasium. The beams include a clear span of 147 ft over the gymnasium auditorium. The upper and lower truss chords are BLC 25.82x103.34-inch beams oriented flat, while the truss web includes BLC 5.51x7.87-inch compression members and 0.27 x 18.07 x 18.07-inch tension and diagonal members. This optimal truss configuration gradually distributes the internal forces with the appropriate stiffness, meaning additional stiffness at the supports and reduced stiffness near the mid-span. The diamond-shaped frame allows natural filtration of daylight.
Project Design Engineers and Calculation Tools
The engineering company Arborescence, in collaboration with the engineering company CBS-CBT, utilized RFEM to analyze the structure and RF-DYNAM Pro to perform the seismic analysis.

- How can I connect surfaces to other surfaces or members in a hinged/semi-rigid way? What are Line Hinges and Line Releases?
- How is the dimension for an equivalent round section calculated in the Timber Design add-on?
- I have a 3D model and try to split it up into "walls" and "surfaces" with the Building Model and to calculate them separately. However, my structural system becomes unstable then. What can be the reason?
