Dr Taxiarchoula Limnaiou is a Geotechnical Engineer at GR8 GEO. She has extensive experience in advanced constitutive modeling of geomaterials, as well as in advanced 2D and 3D numerical analysis of onshore and offshore geotechnical projects, with emphasis on soil-structure-interaction under static, dynamic, and cyclic loading conditions.
As part of the GR8 GEO team, Taxiarchoula has been involved in various projects around the world, including site response analyses for the development of design ground motions in seismically active areas, performance-based design for liquefaction problems and static and dynamic SSI analyses for shallow and deep foundations. She has performed 3D numerical evaluations of suction bucket and monopile foundations under static, earthquake, wind and ice loading for offshore wind farm projects. She participated in the geotechnical design of the 32 km-long Bataan-Cavite Interlink Bridge in the Philippines, where she conducted 3D effective stress numerical analyses for the design of large-diameter caisson foundations supporting Cable Stay Bridge foundations.
She has been also involved in GR8 GEO’s R&D activities. She contributed to the validation of the Ta-Ger constitutive model for clays against PISA field tests and developed sets of default model parameters for Ta-Ger models, which can be applied across a range of geotechnical problems. She participated in GR8 GEO’s centrifuge testing campaign, in collaboration with ETH Zurich (ETHZ), focusing on the cyclic and earthquake response of monopile foundations for offshore wind turbines and worked on the numerical simulation and validation of numerical tools against the experimental findings.
As a researcher, her work has been published in several scientific journals and conferences. Her MSc focused on the Analysis and Design of Earthquake-Resistant Structures and her PhD on the Constitutive Modeling of granular soils. During her PhD, under the supervision of Prof. Achilleas Papadimitriou, she developed a constitutive model for sands for monotonic and cyclic loading and implemented it in the commercial codes FLAC and FLAC3D. In parallel, she has extensively worked on numerical analyses related to liquefaction- induced hazards on lifelines and existing infrastructure and on the suggestion of mitigation measures.
