Modalanalyse von Monitoringdaten eines Sendeturms

Abstract: 1 Einleitung Für eine Vielzahl von bestehenden Bauwerken, insbesondere Infrastrukturbauwerken, stellt sich bei Erreichen der geplanten Lebensdauer die Frage der weiterführenden Nutzung. In Fällen, in denen nicht alle Nachweise nach den heute geltenden Normen auf Grundlage von Bestandsunterlagen geführt werden können, besteht die Möglichkeit, das Tragverhalten messtechnisch zu überwachen. Bei vorwiegend durch dynamische Kräfte beanspruchten Bauwerken kommt der Erfassung des dynamischen Strukturverhaltens, besch… Show more

“…In recent years, the development of automated procedures for identifying modal parameters in operating conditions has become increasingly popular and stochastic subspace-based algorithms (SSI) methods have been selected as the most practical tool for this procedure due to the consistency in modal parameters’ estimation, especially under non-stationary noise excitations [ 5 , 6 , 7 , 8 , 9 , 10 , 11 , 12 , 13 , 14 , 15 ]. However, the use of subspace-based algorithms for OMA and structural health monitoring (SHM) will be problematic when applied to structures with rotating machines, due to the harmonic excitations.…”
