Modigliani Forum

Livorno - 1997

The roof cover structure is made by 24 meridian arches arranged with radial symmetry at constant pitch, with an angle at the center of 15° (in plan) and 6 parallel arches arranged each 8°. The mean cover surface is almost a spherical cap with 70m radius and 29m deflection.

At 14m level from reference level 0.00 a prestressed cable ring made by 3 high resistance steel 42mm diameter cables has been provided

The arches are directly supported by the foundation and restrained by cylindrical hinges made by steel.

The cover is a composite system of zinc-coated and painted corrugated steel sheets, such to overcome (without any secondary beam system) the 12m spans between the arches.
