Description

A structurally active textile roof was adopted as part of a tensegrity system in the pavilion's cafeteria. A portable structure was made up of hollow sections, cables and fabric. The roofing material acted as part of the structural system. Steel compresssion and bending members were completed with prestressed membrane and cables, thereby optimising efficiency, saving on materials and providing clarity and flrxibility.

Description of the environmental conditions

General comments, links

The roof was a tensile membrane and worked as part of the structure.Neither purlins, beams or trusses were needed because nine flying masts were pushed upwards by a cable net attached to the horitzontal frame. The flying masts were made of aluminium with a curved plate on top to distribute the loads. At the bottom, four gussets were attached to the turnbuckles of the cable net. Adjustable devices allowed for periodical stressing and ensured ease in the erection and dismantling processes.
