Recently, in Japan, there is a case that the pile end of the building did not reach the firm layer because the soil layer was complicated. In such a case with piles with insufficient length, the existing pile modelling method cannot be applied. There

As a part of the LEAP-UCD-2017 project, type B simulations were performed to predict the results of nine selected centrifuge model tests using a two-dimensional effective stress analysis program incorporating the cocktail glass model. In Phase I of t

This paper describes the numerical sensitivity study requested prior to the December 2017 LEAP workshop. Several but not all of the simulation teams participated in this sensitivity study. The results of the sensitivity study are used to begin to map

A new constitutive model (cookie model) for clay was proposed to establish a prediction method to evaluate damages from complex disasters. The model was developed as an extension of a model (cocktail glass model) for liquefiable sandy soil. The model

The end bearing capacity of a pile is modeled for two-dimensional effective stress analysis by initially conducting a vertical loading test in a centrifugal field and then simulating the vertical loading test by three-dimensional analysis to validate

A granular material consists of an assemblage of particles with contacts newly formed or disappeared, changing the micromechanical structures during macroscopic deformation. These structures are idealized through a strain space multiple mechanism mod
