Description

This roof covers the 12 m wide secondary avenues of the exhibition centre of Valencia (Spain). The modular roofs are arranged as hyperbolic paraboloid or conoid shells made out of corrugated steel sheets. These sheets are supported by bowstring trusses in such a manner as to create the conoid surfaces. The lower chord of the truss bears one edge of a shell while the curved upper chord of the following truss bears the other edge.

In order to cover the 9 m longitudinal span, the corrugated steel sheets compose a double layer structure interspersed with insulation foam and secondary rolled sections which are spot welded to the sheets.

This roof is an innovative example of how corrugated steel sheets, which are commonly used for cladding industrial premises, can be used for modular roof solutions with medium span length.
