COTTONERA SPORTS COMPLEX

• Built as part of infrastructural works hosting the 2003 European

   Small Nations Games. The main focus of the complex is the 

   multipurpose sports hall, seating 1,300 people.

• Primarily designed for Volleyball tournaments with a playing area of

   46m by 28m width and 14m high.

DOME STRUCTURAL CONCEPT

• Use of a single layer framework not ideal due to shallow height to
   span ratio.

• Shallow double-layered steel geodesic dome covering a square plan

   area.

• Lower layer inscribes a square with sides measuring 46.55m and has

  a rise of 4m at the apex.

• Dome upper layer is concentric with the lower layer and is 1.5m

   apart.

• The two layers consist of triangulated grids and are connected

  together by bracing members.

• Each layer is produced by the subdivision of a spherical

  icosahedron, by a frequency of 11 divisions and for each layer there

  are 22 member lengths as there are for the diagonal elements in

  between the upper and lower layers.

• Supported along its perimeter on 44 vertical and 48 inclined

  steel columns, which are anchored to a three-dimensional braced

  concrete framework.
