Microwave Structural Health Monitoring of the Grouted Connection of a Monopile-Based Offshore Wind Turbine: Fatigue Testing Using a Scaled Laboratory Demonstrator

<div>Normalized RMS values of acceleration in the frequency band 0.5–1.5 Hz in load direction (a) and transverse to load direction (b) measured by four MEMS acceleration sensors at the measurement positions T1, T2, Gi0-1, and Ga0-1 during hydraulic excitation at four load levels.</div>
