SHM System of the Roof Structure of Sports Arena “Oliviaâ€

Abstract

The paper presents a structural health monitoring system of the Sports Arena “Olivia†in Gdansk, Poland. The system was installed because of doubts about the roof stability due to observed buckling of the steel truss members. The SHM system was based on nonlinear FEM models used for detection of type of near failure modes of the roof. The application of detailed FEM model in current state updated on data from in situ loading testes allowed to trace large number of structural parameters necessary for precise identification of the roof structure condition.
