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 anew benchmark is proposed to assess the effect of both, the pore water pressure generationand the liquefaction occurrence. For now, 11 teams, mainly from French institutes, participatein this benchmark. A first iteration of calculation based on a synthetic case has been performedand a second is ongoing. The first iteration of the LICORNE (Liquefaction and CyclicmObility Representation on Numerical Experiments) project highlighted differences in theresults of some numerical codes. In parallel, other codes were able to closely estimate theresponses. A second iteration is ongoing to clarify the inputs and the results form of each teamand propose additional tests to analyse in more detail the stress-strain curves produced byeach team.
