GeoSuite Assistance for the Calculation of Settlement
Lacasse, Suzanne; Jostad, Hans Petter; Kim, Yunhee; Liu, Zhongqiang; Sandven, Rolf Birger (Chapter, 2016)As part of the development of the Norwegian-Swedish software GeoSuite, a module with geoassistance was developed and implemented. The paper describes this user-assistance, called "Wizard", helping the user with 1D, 2D and ... -
GeoSuite – A Modular System for Geotechnical Design
Lacasse, Suzanne; Jostad, Hans Petter; L'Heureux, Jean-Sébastien; Torgersrud, Øyvind; Sandven, Rolf Birger (Chapter, 2016)Remarkable advances in the analysis tools of, for example slopes, embankment stability and settlements have happened since the 90s. Many are due to the information technology revolution in all aspects of geotechnical ... -
Impact of cyclic strain accumulation on the tilting behaviour of monopiles in sand: An assessment of the Miner's rule based on SANISAND-MS 3D FE modelling
Liu, Haoyuan; Pisanò, Federico; Jostad, Hans Petter; Sivasithamparam, Nallathamby (Peer reviewed; Journal article, 2022) -
Load history idealisation effects for design of monopiles in clay
Liu, Haoyuan; Sivasithamparam, Nallathamby; Suzuki, Yusuke; Jostad, Hans Petter (Peer reviewed; Journal article, 2022) -
Modelling mesh independent failure loads of a soft strain-softening clay using a rate dependent model
Rødvand, Laura Anne; Jostad, Hans Petter; Grimstad, Gustav; Andresen, Lars (Peer reviewed; Journal article, 2023) -
Modelling of soil-structure-interaction for flexible caissons for offshore wind turbines
Skau, Kristoffer Skjolden; Jostad, Hans Petter; Eiksund, Gudmund Reidar; Sturm, Hendrik (Peer reviewed; Journal article, 2018)Published foundation models and procedures for calculation of caisson foundation response typically assume a rigid caisson in deformable soil. However, recent published measurement data from a prototype suction bucket ... -
Numerical prediction and back-calculation of time-dependent behaviour of Ballina test embankment
Jostad, Hans Petter; Palmieri, Francesca; Andresen, Lars; Boylan, Noel (Peer reviewed; Journal article, 2017)The paper describes the Class A prediction and Class C back-calculations of the Ballina test embankment using the finite element program Plaxis and the Soft Soil Creep Model (SSCM). The prediction underestimated the measured ... -
REDWIN – REDucing cost in offshore WINd by integrated structural and geotechnical design
Skau, Kristoffer Skjolden; Page, Ana M.; Kaynia, Amir M.; Løvholt, Finn; Norén-Cosgriff, Karin; Sturm, Hendrik; Andersen, H.S.; Nygaard, Tor Anders; Jostad, Hans Petter; Eiksund, Gudmund Reidar; Havmøller, O.; Strøm, P.; Eichler, D. (Peer reviewed; Journal article, 2018)The cost of offshore wind energy production has to be reduced continuously to improve its competitiveness compared to other energy sources. To contribute to this goal, a 4- year research project REDWIN – REDucing cost of ... -
Response of lightly over-consolidated clay under irregular cyclic loading and comparison with predictions from the strain accumulation procedure
Skau, Kristoffer Skjolden; Dahl, Birgitte Misund; Jostad, Hans Petter; Suzuki, Yusuke; Sordi, Jerome De; Havmoller, Ole (Peer reviewed; Journal article, 2022) -
Stability analyses of quick clay using FEM and an anisotropic strain softening model with internal length scale
Grimstad, Gustav; Jostad, Hans Petter (Chapter, 2012)Sensitive soft clays generally display a significant post peak strain softening response under undrained deformation. A consequence of this behavior is that the safety factor during undrained stress changes cannot be ... -
Strain localisation in sensitive clays: can rate dependency provide mesh independent results?
Rødvand, Laura Anne; Jostad, Hans Petter; Grimstad, Gustav; Andresen, Lars (Peer reviewed; Journal article, 2022)
