GEOLAB – WESDOM Project

Within the framework of the GEOLAB Transnational Access project WESDOM (Wind-Earthquake-Storm Design of Offshore Monopiles), GR8 GEO conducted 4 centrifuge tests at the ETH Zurich Geotechnical Centrifuge Center.

The experimental series tested a hollow steel monopile founded in dense (Dr=75-85%), saturated, Ottawa F-65 Sand, under monotonic and cyclic loading  at 60g centrifugal acceleration. The test series comprised: (M2) monotonic lateral pushover; (C1)1-way sinusoidal load-controlled packages of increasing amplitude at the target period T=1s at prototype; (C2)1-way sinusoidal load-controlled packages of increasing amplitude at a range of target periods T=1-3s at prototype scale; and (C3) packages of irregular realistic storm load time-histories of increasing intensity and (EQ1) Earthquake loading using real records of acceleration time histories. The last seismic test is yet to be performed.

This dataset contains the experimental raw data of monotonic (M2) and cyclic tests (C1-C3) as provided by the host facility (GCC ETHZ). A complementary document is attached giving a summary of the conducted centrifuge experiments along with guidelines and specifications of the equipment used.
