A football stadium with mobile roofing. The structural system of this roof is essentially formed by:
- main longitudinal arches with considerable span make up the main supporting structure.
- lateral roofing of the stands which cover the stand areas of the external border and the longitudinal arch; the type adopted for this structure is of circular configuration reticular beams, arranged in a radial manner.
- Central roofing with fixed and mobile panels, made of two types of structure: one fixed and the other mobile (corresponding to the football pitch area which is equal to about 90 x 110 metres); the type foreseen for this structure is reticular spatial with hot rolled open profiles; the driving mechanism is of particular importance for the movement of the roofing.
