Nonlinear numerical simulation of physical shaking table test, using three different soil constitutive models

چکیده
Dynamic response records of pile performance during earthquakes are limited mainly due to the challenges recording seismic soil–pile response. This limitation has led an inadequacy in providing a standardized basis for calibration and validation available analytical numerical methods developed superstructure interaction problems. To bridge this gap, series simulations scaled, shaking table tests model piles soft clay been current study. paper aims accurately identify all aspects critical parameters simulation propose most suitable soil constitutive model. Three models selected as advanced soil, namely, modified Mohr–Coulomb, Drucker–Prager/cap plasticity, Cam–clay models. Similar physical test case study, analysis uses dimensional techniques scale modelling criteria develop scaled pile-supported structure correctly. The 3D nonlinear using Abaqus software.

Numerical Simulation of Piles Subjected To Lateral Spreading and Comparison with Shaking Table Results
Pile foundations are relatively vulnerable to lateral loads. During liquefaction-induced lateral spreading, this vulnerability is particularly conspicuous due to a loss of strength and stiffness in the liquefied soil. A nonlinear effective stress analysis incorporating an elastoplastic constitutive model based on Finite Difference Method (FLAC2D program) was used to numerically simulate shake t...
متن کاملSimulation of Soil Temperature Dynamics with Models Using Different Concepts
This paper presents two soil temperature models with empirical and mechanistic concepts. At the test site (calcaric arenosol), meteorological parameters as well as soil moisture content and temperature at 5 different depths were measured in an experiment with 8 parcels realizing the combinations of the fertilized, nonfertilized, irrigated, nonirrigated treatments in two replicates. Leaf area dy...
متن کاملinvestigating dynamic response of a buried pipeline in sandy soil layer by 1g shaking table test
investigating the parameters influencing the behavior of buried pipelines under dynamic loading is of great importance. in this study the soil structure interaction of the pipelines with the surrounding soil was addressed using shaking table tests. wave propagation along the soil layers was also included in the study. the semi infinite nature of the field was simulated using a laminar shear box...
متن کاملApplication of Two Different Constitutive Models for Numerical Simulation of Liquefaction
Liquefaction phenomenon in saturated loose sandy layers occurs as an undrained response of soil when it is subjected to static or dynamic loads. A fully coupled dynamic numerical program is developed to predict the liquefaction potential of saturated sandy layers. Coupled dynamic field equations of extended Biot’s theory with u-p formulation are used to determine pore fluid and soil skeleton re...
متن کاملNumerical Discrete Element Simulation Of Soil Direct Shear Test
One of the most common methods to measure soil mechanical properties (namely cohesion and internal friction angle) is direct shear box test. In this paper the development of a three-dimensional (3D) discrete element soil model for simulation of a cohesive soil’s direct shear test is presented. The aim was to calibrate the properties of the Hertz-Mindlin with bonding contact model available in E...
