LICORNE a benchmark on numerical method for non-linear site response analysis involving pore water pressure

Following the benchmark PRENOLIN for 1D non-linear site response analysis a new benchmark is proposed to assess the effect of both, the pore water pressure generation and the liquefaction occurrence. For now, 11 teams, mainly from French institutes, participate in this benchmark. A first iteration of calculation based on a synthetic case has been performed and a second is ongoing. The first iteration of the LICORNE (Liquefaction and Cyclic mObility Representation on Numerical Experiments) project highlighted differences in the results of some numerical codes. In parallel, other codes were able to closely estimate the responses. A second iteration is ongoing to clarify the inputs and the results form of each team and propose additional tests to analyse in more detail the stress-strain curves produced by each team.
