The Foro Sur building is one of the premises of the Valencia Exhibition Centre. The lower part of the building houses a tram station which is serving the Exhibition Centre.
The building has a conventional reinforced concrete structure and its main feature lies in the large steel space-frame roof with the form of a spiral shell which covers the central hall of the building.
This roof represents a formal development of the system employed in the existing lamella roof at the Exhibition Centre.
The chosen structural solution consists in the arrangement of a triangular steel space frame with standard joints.
