SYMPOSIUM TOPICS
Numerical simulation in geomechanics, constitutive aspects, soil-structure interaction and associated structural analysis with emphasis on present and future engineering practice: theory, applications, case studies, failure analyses, optimisation, probabilistic approaches.
SYMPOSIUM HISTORY
The symposium combines invited presentations, and contributions by ZSoil users and others. It has been taking place every year in late summer over the past twenty years, at the Swiss Federal Institute of Technology, in Lausanne and newly at Haute Ecole d’Ingénierie et d’Architecture de Fribourg.
Confirmed talks
- Keynote lecture Th. Zimmermann (Zace): ZSoil, forever young
- K. Dziedzic/R. Obrzud (GeoDev) : Towards integrating a spatial analysis of geotechnical data into FE model creation
- J. Zannin/S. Marceta/R. Obrzud (KF): Design of heat exchangers based on thermal response measurement and numerical simulations in ZSoil
- R. Obrzud (KF): Predicting geostructure performance, digital twinning of large-scale load tests using ZSoil simulations
- R. Maye (KF): Secure deep excavation design near railways based on ZSoil results: insights from the Travis project
- J. Minini/S. Commend (HEIA): Probabilistic vs. deterministic design in Eurocodes 2.0, with potential economic gain
Other potentially invited speakers
- M. Cudny (Gdansk University), M. Borgers (Illwerke), GW. Byun (EG Soft), Ph. Menétrey (IngPhi), A. Truty & K. Podles (CUT), M. Preisig & S. Kivell (GeoMod),
WHO ATTENDS
Engineers and developers confronted with the need to perform accurate numerical simulations or optimisations for complex underground, above ground or combined constructions have an opportunity to exchange experience, see state of the art presentations of recent case studies and get a comprehensive introduction to numerical simulations in 2D or 3D, with ZSoil, in dry or partially saturated rock or soil, with full structural capabilities, soil-structure interaction, interfaces, thermal effects, ultimate load evaluation, continuous safety assessment, including creep, swelling, dilation, dynamics, uncertainty quantification with UQlab etc.
ZSoil
ZSoil is a user-friendly 2D/3D finite element package for soil, rock and soil-structure analysis available and used worldwide since 1985, and continuously upgraded. The program was developed at Zace Services Ltd, by a team of engineers with research experience at the Swiss Federal Institute of Technology in Lausanne, UC Berkeley, California Institute of Technology, Purdue University, Cracow University of Technology, Stanford University and UC Davis. The aim is to provide civil engineers with a simple tool to accurately support geomechanical and structural engineering analysis, dimensioning and optimisation. Since ZSoil first came out in 1985 it has steadily gained worldwide acceptance among practitioners as well as teachers and researchers. Today, upto ten free student versions are downloaded every day.
