In a recent paper published by Computers and Geotechnics in collaboration with the University of Kassel, the AVISA model (Tafili & Triantafyllidis, 2020) is applied on the case study of the piled raft of Messeturm in Frankfurt, for which extensive measurement data are available. The simulations comprise both the construction phase and the subsequent long-term deformation due to creep using Tochnog.

In a recent paper published by Computers and Geotechnics in collaboration with the University of Kassel (Aljoscha Ganal and Prof. Oliver Reul), the AVISA model (Tafili & Triantafyllidis, 2020) is applied on the case study of the piled raft of Messeturm in Frankfurt, for which extensive measurement data are available. The simulations comprise both the construction phase and the subsequent long-term deformation due to creep using Tochnog. The calibration of the parameters was done using experiments of Frankfurt clay. Additionally, suggestions for the initialization of state variables, the choice of parameters, and the constraints of their values to prevent numerical instabilities are provided.    Tafili, M., Ganal, A., Wichtmann, T., & Reul, O.
