PLAXIS

The first contribution is a research project on automatic parameter identification using a population-based stochastic optimization method.Different material models were used to simulate the behaviour of reconstituted and natural Pisa clay. The second contribution is the analysis of a patented wall structure against ice loads using 3DFoundation. Key issue was the development of failure criteria for the structure and to prove that it would not fail under extreme conditions. The third contribution demonstrates the use of PLAXIS to analyse the liquefaction potential of a revetment geometry using the cyclic stress approach. A comparison is made between the PLAXIS results and the results of a 1D program that is generally used in geotechnical earthquake analysis. In addition to the contributions by PLAXIS users, there is a joint presentation about a project where Plaxis has provided expert services to a client.
