The main structural system are:

• Main Sport Hall roof cover;
• Training Hall roof cover;
• Retractable pavement.

The main structure is made by a system of steel cables, that splits the building in two symmetrical parts giving an uniform dynamic behaviour to the entire building. The two sub-structures are made by huge anchorage concrete blocks and a group of cables trusses. The transversal beams are supported by concrete structures outside, while they are suspended to the central tensile-structure with a special pendulum. The structural roof system is made by a longitudinal system of prestressed cables and cover sheets.

The Training Hall roof cover is made by a double layer steel structure supported by cables.

The pavement, moved by a special system of hydraulic jacks, can assume a double vertical place to face every spectators need in each sport discipline.
