Abstract: LEAP (Liquefaction Experiments and Analysis Projects) is an international effort to perform model tests to assess the accuracy of numerical procedures for predicting the effects of liquefaction. Quantitative assessments of accuracy of a numerical procedure depend on knowing the accuracy and uncertainty of the reference experimental data. To understand the accuracy and uncertainty of the data, the inter-laboratory reproducibility of the experiments must be established. Since repeatability is not perfect, the assessment of differences between experiments should be interpreted with rigorous consideration of the variability of initial conditions and boundary conditions and knowledge of the sensitivity of the results to the variations of these conditions. While the LEAP project is focused on liquefaction problems, it is believed that the validation approach developed for LEAP has applicability to many other disciplines.
