The main structural system for the Sport Arena in Pesaro is a double layer spatial truss arranged in order to have a mean surface with positive total curvature. The structural system is made by the following sub-systems:

• Central spatial truss arch with variable span from 110m to 22m;
• Transversal truss beams at both arch sides, whose shape is defined by two arches with same centre and radius;
• Stabilizing system for roof structure pretensioning with a group of stabilizing cables at beams extrados.
