High Strength Steel in Friends Arena

Designing a roof for a large arena with many initial requirements for an outdoor feeling and flexibility for different events, etc., is a world-class challenge. The main task is to find a functional system based on intuition, experience and rough estimates. Furthermore, it is important to limit the load especially from dead weight by using lightweight materials and optimization of secondary structures. It is also necessary to design with high material utilization of every element in the primary framework by varying the size of the profiles and their plate thicknesses, so called tailor-made design. When using high strength steel on top of these optimizations, it is possible to considerably reduce weight and cost.
