Sub-minute fatigue monitoring for enhanced lifetime assessment of wind turbines

Abstract. Accurate fatigue damage estimation is a critical step for managing and extending the life of wind turbine fleets, and the basis on which operators decide whether an ageing asset can be kept in service beyond the end of design life. The most accurate estimation relies on...

Numerical Modeling and Experimental Tests for Dynamic Characterization of Foz Tua Arch Dam

The understanding of the dynamic behavior of an arch dam and its evolution over time provides important data for safety control procedures. Forced vibration tests remain a reliable technique for dynamic characterization, providing the response to excitation levels higher than amb...
