CiteSeerX - Document Details (Isaac Councill, Lee Giles, Pradeep Teregowda): The present paper deals with the influence of soil non-linearity, introduced by soil liquefaction, on the soil-foundation-structure interaction phenomena. The objective is to reveal the beneficial or unfavourable effects of the non-linear SSI on both structural drift and settlement of a given structure.

The experimental data provided a unique basis for assessing the capabilities of twelve different simulation platforms for numerical simulation of soil liquefaction.

The results of the experiments and the numerical simulations are presented and discussed in papers submitted by the project participants. As such the book addresses the comprehensive hazard analysis of seismic soil liquefaction, including factors such as macroscopic characteristics, evaluating the liquefaction potential, dynamic characteristics and deformation processes, providing reliable evaluation results for liquefaction potential and deformation in the context of risk Cited by: 2.

Model Tests and Numerical Simulations of Liquefaction and Lateral Spreading: LEAP-UCD by Bruce L. Kutter English | EPUB | | Pages | ISBN: | MB This book presents work collected through the Liquefaction Experiments and Analysis Projects (LEAP) in It addresses the repeatability, variability, and sensitivity of lateral spreading observed in twenty-four.

Numerical simulations are carried out so as to study an improvement method to reduce the liquefaction potential in a sandy soil profile subjected to a shaking.

(, ) is conducted. Comparisons between the experiment and the numerical simulation show that the numerical simulation.

Early liquefaction is observed in the numerical simulation, as also found in the experiment, but agree only during the period of shaking. In the numerical model, at the end of shaking, the permeability of the soil was increased to a value four times higher than that used during the shaking [16] but the centrifuge test shows an even more rapid rate of decrease in pore pressure ratio after the end of by: method to numerical simulation of liquefaction-induced large deformation is examined.

A dynamic centrifugal model test for a liver levee mounted on liquefiable foundation ground is numerically simulated. The input motion is a simple wave with constant amplitude and frequencs ies. Numerical Simulation of Optical Wave Propagation is solely dedicated to wave-optics simulations.

The book discusses digital Fourier transforms (FT), FT-based operations, multiple methods of wave-optics simulations, sampling requirements, and simulations in atmospheric s: 7. A numerical approach to the evaluation of the liquefaction susceptibility of layered soils during strong earthquakes is presented.

About this book With the advent of super computers during the last ten years, the numerical simulation of viscous fluid flows modeled by the Navier-Stokes equations is becoming a most useful tool in Aircraft and Engine Design.

In this paper, numerical simulation of 3-dimensional assemblies of polydisperse sphere particles using Discrete Element Method (DEM) is used to study the liquefaction behaviour of granular materials.

Comparisons between the experiment and the numerical simulation show that the numerical simulation is capable of reproducing almost all main characteristics of the repeated. An integrated numerical model is developed to study wave and current-induced seabed response and liquefaction in a flat seabed.

The velocity-inlet wave-generating method is adopted in the present study and the finite difference method is employed to solve the Reynolds-averaged Navier-Stokes equations with k-ε turbulence closure. The model validation demonstrates the capacity of the present model.

The excess pore water pressure response behaviors of soil foundations, and the effectiveness of different types of drainage or reinforcement measures were investigated using Finite Element Method (FEM). FEM numerical model is a coupled stress-flow finite. Previous case histories have shown that soil liquefaction severely damaged many structures supported on pile foundations during earthquakes.

As a result, evaluating the potential for instability is an important consideration for the safe and.Book Description.
