On 22 March 2011, the structure was devastated by fire. The main room is unusable. The steel structure is deformed, the walls and roofs are destroyed, but the facade is intact. In 2014, studies of a new steel structure were entrusted to the Engineering office Duberseuil & Cie. The old steel framework was classified as a “historical monument” since 1989. The new structure had to include the same architecture. However, the rules and standards of construction forced a reconsideration of the design of the new structure. A survey of the structural elements of the old framework was established. The building is 39 metres long by 22.5 metres wide and has a ridge height of 12.6 metres. To compensate for the noise pollution caused by the operation of the site, a double framework was created in the roof spaced at 80 cm, allowing the installation of a double insulation and a vacuum between two of 60 cm. The columns are supported by anti-vibration base-plates to block any transmission of the vibrations in the vicinity. The natural frequency of the mezzanine was checked to respect 3 Hz. The stage structure was designed to be removable by jacks on different levels. The roof structure takes into account the elements of lighting and sound diffusion as well as decorative elements. All the structural elements were modelled and calculated with a buckling check and lateral torsional buckling check.
