Abstract

This paper presents a theoretical framework for scaling 1g model pile tests proposed to study the accumulated axial displacement and stiffness of piles under long-term cyclic loading for offshore wind structures. Performance data for piles under long-term cyclic loading are sparse and thus 1g physical models may be a cost-effective alternative if the physics can be appropriately scaled. Non-dimensional expressions are proposed that can be used to design 1g model pile tests in cohesionless soils and interpret model test data. The proposed framework still requires experimental validation and a testing program has already been initiated at the University of Rhode Island for this purpose. © 2012 American Society of Civil Engineers.
