A 3D model for earthquake-induced liquefaction triggering and post-liquefaction response

Nonparametric Liquefaction Triggering and Postliquefaction Deformations

This study evaluates granular liquefaction triggering case-history data using a nonparametric approach. This approach assumes no functional form in the relationship between liquefied and nonliquefied cases as measured using cone penetration test (CPT) data. From a statistical perspective, this allows for an estimate of the threshold of liquefaction triggering unbiased by prior functional forms,...

Parallel Finite Element Modeling of Earthquake Ground Response and Liquefaction

Parallel computing is a promising approach to alleviate the computational demand in conducting largescale finite element analyses. This paper presents a numerical modeling approach for earthquake ground response and liquefaction using the parallel nonlinear finite element program, ParCYCLIC, which is designed for distributed-memory message-passing parallel computer systems. In ParCYCLIC, finite...

Simulation of Earthquake Liquefaction Response on Parallel Computers

This paper presents a parallel nonlinear finite element program, ParCYCLIC, which is designed for the analysis of cyclic seismically-induced liquefaction problems. Key elements of the computational strategy employed in ParCYCLIC include the deployment of an automatic domain decomposer, the use of the multilevel nested dissection algorithm for the ordering of finite element nodes, and the develo...

Liquefaction Triggering Criterion Using Shake Table Test

Earthquake induced liquefaction in saturated granular soils is an important phenomenon causing severe damages. In order to minimize the ill-effects due to liquefaction, various lab tests, field tests are being used which assess the liquefaction potential. In the present study the shake table test has been used for assessing soil liquefaction of loose saturated cohesionless sand by simulating ea...
