Abstract
The original roof, finalized in 2003 did fail shortly after the installation process during a thunderstorm. The complete membrane was destroyed but the main masts were still in place and not damaged. It was then decided to replace this roof by a more redundant system, but with the same appearance. Main goal for the redesign was to avoid any modification on the main masts, and ideally no replacement of the main suspension cables.
The design was started with the evaluation of different types of large scale cable nets, to achieve a system with a comparable load bearing behaviour. It ended up with a pentagon and hexagon pattern, forming a similar shape like the previous membrane roof, and so with a comparable geometric stiffness.
