The tensile structure for the Olympic stadium roof system is made by a system of 88 planar radia tensile structures made by a bearing/stabiling cable and vertical stays, every 12m.

The cables are anchored in the outer part at the nodes of a spatial compression ring, while they are anchored inside to the tensile ring.

Depending on the stress and deformation status, planar tensile structures have been designed and split in two groups.

Secondary radial beams are also provided, made by truss beam, hanged at stabilizing cable level as simple support in order to bear the cover made by PTFE and fiber glass membrane.
