Metalkarma Spaceframe provides roof structure for sports Indoor stadiums such as
- Table Tennis
- Boxing & Wrestling
This large area was to be covered by adopting such a structural system, which can achieve predefined objectives of appealing appearance, cost effectiveness, and ease of construction while using locally available materials, skills and equipments. Structural system adopted for the roof is double layered braced barrel vault in metal.
Braced barrel vault was adopted due to its aesthetics and economy in material consumption. The vault was idealized as a series of two hinged arches, laterally braced by horizontal and diagonal bracings. Structural system for the roof supporting structure is a series of innovatively conceived tripod shaped space frame in concrete.
