Abstract

A new ice hockey stadium has been built in Tampere, Finland. It has a reinforced concrete structure and a light, double curvature, roof suspended from a network of prestressed cables. It has a rectangular planform, 63x92 m, and it can accommodate 10,000 spectators. The hockey rink is in the centre. After a brief comparison of various types of suspended roofs, the author describes his own design, and discusses the most delicate aspects of the project. The cables are anchored in lateral arched beams, whose stability is provided by external prestressed concrete ribs. The author emphasizes the importance of these beams for the overall efficiency of the project. Special care was taken to avoid curvature of the cables where these penetrate into the lateral beams, without, however, restricting the freedom of the cables to oscillate. The article describes the placing of the cables, the details of the cables themselves, and their stretching: all of which is a technology that is now well know and tried.
