N2  - Wind turbine structures take a major role in the
modern conversion to renewable energy sources and
contribute to the creation of a greener world. In recent
years, the development and installation of wind
turbines have seen rapid growth. However, with the
increasing capacity and size of wind farms worldwide,
there are growing concerns about the safety and reliability
of these installations. Therefore, structural
health monitoring and the detection of damage to
wind turbines have gained considerable importance in
research. Wind turbine blades are particularly susceptible
to various types of damage due to environmental
influences. This article provides an overview of signal
responses, sensors used and non-destructive testing
techniques in the field of damage detection on wind
turbine blades. The intention of the article is to give
an insight into the possibilities of structural health
monitoring and at the same time to point out unsolved
problems in this field.

N2  - Die Standsicherheitsbeurteilung alter gemauerter Kanäle mit Eiprofil wird dadurch erschwert, dass neben den Unwägbarkeiten der Materialeigenschaften und des Baugrundes keine Regeln zur Nachweisführung vorliegen. ln Anlehnung der Schnittgrößenermittlung an das Arbeitsblatt ATV-A 127 ergeben sich insbesondere bei bestimmten Tiefenlagen rechnerisch unzureichende Sicherheitsbeiwerte, die jedoch offensichtlich mit der örtlich erreichten Tragfähigkeit nicht übereinstimmen. Um die im Sammler-Baugrund-System auftretenden Lastabtragungen zu erkennen und um diese in einem Rechenmodell nachzubilden, wurden die Untersuchungen an einem Abwassersammler in Bremen durchgeführt.
N2  - The assessment of the stability of older egg-shaped brickwork sewers is difficult because in addition to the uncertainties of the properties of the material used as well as the foundation there are no design codes for structural analysis. lf Worksheet ATV-A 127 is closely followed in calculating the cross section forces, insufficient safety coefficients are obtained, above all for certain depths; however these do not coincide with the load bearing capacity achieved locally. ln order to identify the load carrying capacity of the sewer-soil-system and to simulate them in a calculation model, studies were carried out in an interceptor in Bremen.
