Stabilizing Cable Domes

Despite their light weight and efficiency, cable domes have been used relatively little, due to the difficulties of stabilization and installation. That is why an adjustment method has been developed, starting from the desired shape, counteracting compressions and limiting displacements by pre-stressing. On the other hand, to overcome the difficulties that arise when it comes to assembly, some adopted solutions are presented.

Cable Dome

Conclusions:

A 10-step procedure has been presented for the stabilization of the cable dome during the design process.
Key elements for introducing the pre-stress are the outer diagonals and loop.
The most affected members are masts and cable stays; the critical load combination is self-weight + pre-stress + snow load.
Several procedures have been mentioned to maintain stability during the installation process.
The impact of the compression ring deserves further investigation.
