BayArena Leverkusen

© Bayer 04 Leverkusen Fußball GmbH

The BayArena was updated to suit the current standards economically as well as technically through extensive modernization and expansion. Due to the very limiting boundary conditions a roof structure covered with makrolon, which transfers the loads to only 8 V-shaped columns was designed. The fact that the ring structure is fulfilling two purposes, to work as a compression ring and as a curved continuous beam, makes this structure exceptional. The few columns and the connection diagonals between the compression rings give the impression of a crown floating in midair. With an area of 28,000 m² the roof is amongst the largest makrolon roofs in the world. The technical challenge was to combine a soft cable structure and a stiff substructure for the makrolon: the solution lies in the development of a flexible substructure capable of adapting to the cable deformations without restraining the makrolon tiles.
