Cable System – Short Technical Description
The bridge is designed as a cable-supported arch system, where the deck is suspended from a single, diagonally oriented steel arch.
- The deck is carried by 30 locked-coil steel cables, acting as vertical hangers between the arch and the deck.
- These cables transfer tensile forces from the deck (traffic loads: tram, pedestrians, cyclists) directly to the arch.
- Structurally, the system behaves as a network of tension elements, ensuring:
- efficient load distribution
- minimal bending in the deck
- The cables are arranged in a semi-radial pattern along the arch, creating a visually asymmetric but structurally balanced system.
⚙️ Structural Role of the Cables
- Primary function: load transfer in tension (deck → arch)
- Secondary function: stabilization of the slender deck
- Interaction:
- cables (tension)
- arch (compression)
→ forming a classic arch–cable equilibrium system
