Dr Panagiota Tasiopoulou is a Senior Engineer at GR8 GEO and leads many of the R&D activities. She has over 10 years of experience specializing in advanced constitutive modelling and numerical analyses and has co-authored 13 journal papers. She has performed advanced numerical analyses for a wide range of onshore and offshore projects involving the assessment of foundation performance under dynamic and cyclic loading.
After completing her PhD in 2015, she worked as an Independent Consultant and has led the numerical modelling work of several projects involving liquefaction problems. She has participated in a number of projects involving dynamic site characterization, site response analyses and development of ground motions in the Netherlands and in Turkey. From 2016 to 2017 she worked on the assessment of the seismic performance of the Eemshaven-Delfzijl and Eemskanaal Levees in Grongingen, the Netherlands due to the occurrence of gas-exploration-induced earthquakes. As part of this project she performed 2D effective stress numerical evaluations and she also led the numerical work on the investigation of the cyclic behaviour of laminated sand and clay deposits using advanced constitutive models in FLAC 2D.
Since the formation of GR8 GEO she implemented the Ta-Ger model for sand developed during her PhD in FLAC 2D and 3D. Subsequently, she has been building GR8 GEO’s modeling tools by developing 2D and 3D numerical applications for research and industry projects. These include tools to assess projects where the response of soils to dynamic and cyclic loading conditions is a critical design aspect, such as the earthquake performance of foundations on liquefiable/soft soils and the cyclic response of OWT foundations subjected to wind/wave loading.
Recent achievements include further developing the Ta-Ger constitutive model to account for partially drained conditions, model calibrations to develop default model parameters for a range of problems and validating the model performance at system level against centrifuge and field tests. She participated in the Liquefaction Experiments and Analysis Projects (LEAP-2020), and notably provided the most successful Class B predictions for a retaining wall with liquefiable backfill subjected to earthquake loading.
