With the dome of the Louvre Abu Dhabi, a museum planned in the capital of the United Arab Emirates, a new architectural highlight will be completed by 2015. The structure consisting of steel has a diameter of 180 m and covers the new local branch of the Louvre Museum in Paris.
The new museum was designed by the famous French architect Jean Nouvel. The Austrian company Waagner-Biro from Vienna has been responsible for the structural calculation and the construction of the dome.
The dome rests on only four support points arranged at a distance of 110 m, which gives the impression that the roof hovers above the museum pavilion below.
The intention of the roof covering consisting of several layers of aluminum sections is to create similar lighting conditions as they occur in an oriental bazaar where woven mats cover the narrow streets. In this way, the dome's supporting structure is visually pushed into the background.
The structural system is based on a space frame consisting of approximately 11,000 member elements with an average length of 4-5 m each. The spatial grid made of triangles and quadrangles was developed by Buro Happold.
The structure is supported by four resettable spherical bearings. It was important to consider their frictional resistance and the restoring force of the supports for the modeling.
The loading that acts on the structural analysis model was analyzed intensively by Waagner-Biro. They also consulted the technical planners about it. For example, the local load transfer has been considered by service meshes. When service technicians step on these meshes, the adjacent members must absorb the additional transverse loading.
The target is to get an ideal dome shape without any visible sag when it will be finished. Therefore, it was necessary to camber the structure for mounting. With this, another effect had to be taken into account in addition to the deformation components from the self-weight.
Over time, the tolerances in the bolt connections of the members will lead to a sliding of the connections, and this in turn causes further sagging of the dome.
Waagner-Biro: “A new icon of architectural steel construction is created with the dome of the Louvre Abu Dhabi.”
