Hangars for the Aferpi Steelworks

As part of the redevelopment and improvement project of the AFERPI steelworks in Piombino, the structures of the existing hangars of the old ingot mill were rechecked following the loads imposed by the new production cycles and the new regulations.
The hangars have a static scheme of a moment-resisting frame with a trussed beam in the transverse direction, while in the longitudinal direction the structure is braced. The main truss is made of angular profiles and bolted joints. The spans of the hangars vary between 30 and 45m; the welded I-section posts are placed at a distance of 20m with false trusses at a distance of 5m and longitudinal beams of the roof.
