Online from HEIA Fribourg Switzerland,
Friday 27.8.2021 09.00 – 17.30,
Organised by Zace Services Ltd, Geomod Ltd & ITEC-HEIA Fribourg
also celebrating 36 years ZSOIL.PC

A special accent is put this year on Uncertainty Quantification and Reliability Analysis.

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.

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 fifteen years, at the Swiss Federal Institute of Technology, in Lausanne and newly at Haute Ecole d’Ingénierie et d’Architecture de Fribourg.

5 lines abstracts of papers on topics linked to NUMERICS IN GEOTECHNICS & STRUCTURES, state of the art contributions on dry or partially saturated rock or soil, soil-structure interaction, interfaces, thermal effects, ultimate load evaluation, safety assessment, optimization, can be submitted any time. Notification of acceptance will be given on/before June 30th.2020 . Presentations in final form will be due 22.8.2020, for distribution to participants.
Please submit abstracts to:

Recent advances in ZSOIL.PC.

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, in particular with ZSOIL.PC, in dry or partially saturated rock or soil,with full structural capabilities, soil-structureinteraction, interfaces, thermal effects, ultimate load evaluation, continuous safety assessment, including creep, swelling, dilation, dynamics etc.
The meeting will be an opportunity for people involved in numerics in geotechnics and structures to exchange experience and ideas.

UQLab is a framework for uncertainty quantification which makes uncertainty quantification available for anybody, in any field of applied science and engineering.
It is being developed at ETH Zurich.

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, and Stanford University . The aim is to provide civil engineers with a simple tool to accurately support geomechanical and structural engineering analysis, dimensioning and optimisation. Since ZSOIL.PC first came out in 1985 it has steadily gained worldwide acceptance among practitioners as well as teachers and researchers. Today, unto ten free student versions are downloaded every day.

FEE: 200 EUR (free for speakers & HEIA affiliates, 50% discount for ZSOIL owners,
10 EUR for students). Registration required.
