The New Roof of the Olympic Stadium in Berlin
The paper presents the structural design and the construction of the new roof of the Olympic Stadium in Berlin . The stadium was completely modernised in view of the next World Football Championship and the work is already completed. The paper describes the design concept of both architect and structural engineer, which has had to comply with the requirements set by the client while optimising the design from all points of view, i.e. aesthetic function, cost and safety. Details on the realisation of the steel structure of the roof are also given within the paper.
