Abstract

In recent years, liquefaction phenomena induced by earthquakes have attracted considerable attention and extensive research has already been performed on various aspects. Also, many constitutive relations have been proposed in order to represent the deformation behavior during cyclic loading. These models, however, have mostly been verified by comparison stress or strain control element tests, and there have not been many numerical tests applying them to the boundary value problems. In this study, a simple and practical constitutive relation which is able to simulate the unelastic behavior of soils under multi-directional cyclic stresses is proposed. The proposed model has been introduced with the computer code ( DIANA-J ), and the accuracy of this model is examined by comparing the numerical results with the experimental ones.

Liquefaction Analysis by Multi-Surface Model

St. Louis, Missouri

In recent years, liquefaction phenomena induced by earthquakes have attracted considerable attention and extensive research has already been performed on various aspects. Also, many constitutive relations have been proposed in order to represent the deformation behavior during cyclic loading. These models, however, have mostly been verified by comparison stress or strain control element tests, and there have not been many numerical tests applying them to the boundary value problems. In this study, a simple and practical constitutive relation which is able to simulate the unelastic behavior of soils under multi-directional cyclic stresses is proposed.
