Report on geotechnical tests with model structures Work Package - Deliverable number: WP 7.2 – D72.2: Report on geotechnical tests with model structures Work Package - Deliverable number: WP 7.2 – D72.2

This report aims to give a comprehensive summary of the geotechnical tests with model structures that have been performed in work package 7.2 task 7.2.2 within the IRPWIND project. The large-scale tests are intended to determine soil-structure interaction effects in order to support probabilistic calculations of the reliability of offshore wind turbine support structures. These calculations are mainly performed in work package 7.4 of the IRPWIND project. However, this report already includes the development of a probabilistic model for the axial bearing capacity / resistance that is obtained using a CPT-based approach and the data obtained by large-scale tests. The main part of this report summarizes the test procedures, first test results, and in some cases the theory behind the tests or the data analysis.
