This book was released on 2022-01-26 with total page 242 pages. Available in PDF, EPUB and Kindle. Book excerpt: In order to describe soil–structure interaction in various situations (nonlinear, static, dynamic, hydro-mechanical couplings), this book gives an overview of the main modeling methods developed in geotechnical engineering. The chapters are centered around: the finite element method (FEM), the finite difference method (FDM), and the discrete element method (DEM). Deterministic Numerical Modeling of Soil–Structure Interaction allows the reader to explore the classical and well-known FEM and FDM, using interface and contact elements available for coupled hydro-mechanical problems. Furthermore, this book provides insight on the DEM, adapted for interaction laws at the grain level. Within a classical finite element framework, the concept of macro-element is introduced, which generalizes constitutive laws of SSI and is particularly straightforward in dynamic situations. Finally, this book presents the SSI, in the case of a group of structures, such as buildings in a town, using the notion of metamaterials and a geophysics approach.

Available in PDF, EPUB and Kindle. Book excerpt: Distributed in the East European countries, China, Northern Korea, Cuba, Vietnam and Mongolia by Academia, Prague, CzechoslovakiaThis book is based on the efficient subsoil model introduced by the authors in 1977 and applied in the last ten years in the design of foundations. From the designer's point of view, the model considerably reduces the extent of the calculations connected with the numerical analysis of soil-structure interaction. The algorithms presented are geared for use on mini- and personal computers and can be used in any numerical method. A special chapter is devoted to the implementation of the model in the NE-XX finite element program package, illustrated with diagrams, tables and practical examples.Besides presenting the energy definition and general theory of both 2D and 3D model forms, the book also deals with practical problems such as Kirchhoff's and Mindlin's foundation plates, interaction between neighbouring structures, actual values of physical constants of subsoils and natural frequencies and shapes of foundation plates.Today, researchers and engineers can choose from a wide range of soil models, some fairly simple and others very elaborate. However, the gap which has long existed between geomechanical theory and everyday design practice still persists. The present book is intended to suit the practical needs of the designer by introducing an efficient subsoil model in which the surrounding soil is substituted by certain properties of the structure-soil interface. When a more precise solution is required, a more sophisticated model form can be used. Its additional degrees of deformation freedom can better express the behaviour of layered or generally unhomogeneous subsoil. As a result, designers will find that this book goes some way towards bridging the above-mentioned gap between structural design theory and day-to-day practice.

Available in PDF, EPUB and Kindle. Book excerpt: For the seismic performance assessment of new and retrofit structures it is important to consider the effects of soil-structure interaction. Several numerical methods of varying complexity and accuracy have been used to evaluate these effects in practice, including the numerical programs, SHAKE and SASSI, which perform ground response analysis using an equivalent linear method, and soil-structure interaction analysis using a frequency-domain substructuring method, respectively. This study involves the assessment of these programs using a database of building responses recorded from a centrifuge test performed at the NEES@UCDavis centrifuge facility, as a part of the NEES City Block project. The centrifuge test involves shaking of two isolated, small-scale building models placed on dry Nevada sand, whose counterparts at the prototype scale are representative of typical low- to medium-rise SMRF buildings situated in downtown Los Angeles. Seventeen ground motions with increasing damage potential are applied to the models. Three of these seventeen excitations are simulated using the programs SHAKE and SASSI to calculate the free-field response of the soil, and the response of the soil-structure systems, respectively. These three ground motions include a low, medium and high intensity motion. Soil-structure interaction effects are calculated from the responses, and a comparison is made between the numerical results and experimental observations. The numerical predictions for the low intensity motion are good. For the higher intensity motions, the nonlinear response of both the soil and the structures was only captured approximately. SSI calculations are also carried out using the simplified procedures of ASCE 7-10 and FEMA 440, and results are compared with the experimental observations.

This book was released on 2019 with total page 110 pages. Available in PDF, EPUB and Kindle. Book excerpt: The increasing shift towards performance-based geotechnical earthquake engineering design requires an improved understanding of soil-structure interaction (SSI) for buildings on liquefiable deposits. While a number of authors have used centrifuge tests and numerical modelling to study this phenomena, a limited number of studies have been undertaken where numerical models have been validated against well-instrumented centrifuge tests. The focus of this research is to validate numerical simulations of ‘free-field’ conditions and numerical simulations of soil-structure interaction response of isolated buildings on liquefiable deposits against measurements from a centrifuge experiment. The 1D simulations for this study have been developed using the PM4Sand constitutive soil model as implemented in FLAC and the PDMY02 constitutive soil model as implemented in OpenSEES. The consideration of two soil models is one of the distinctive features of this study, as one of the objectives of this research is to compare the relative performance of the two constitutive soil models. The 2D numerical simulations to assess the soil-structure interaction response of isolated structures were developed using the PM4Sand constitutive soil model as implemented in FLAC. The 1D validation that was undertaken in this study show relatively good agreement between the simulated and measured accelerations and excess pore pressures using PM4Sand and PDMY02 for up to moderate levels of earthquake shaking. At high levels of earthquake shaking, good results were obtained using PM4Sand but a poor match with measured values was obtained using the PDMY02 model. The centrifuge experiment results appeared to show that the ground motion properties such as duration and the presence of ‘pulse-like’ qualities have an influence on the measured acceleration and excess pore pressure response even if the intensity of shaking is relatively similar. However, this distinction was generally not captured by the two constitutive soil models considered in this study. Additionally, both of the constitutive soil models significantly underestimated volumetric settlements in the ‘free-field’. The 2D validation undertaken in this study showed that, while the numerical simulations were not able to capture volumetric settlements well, the simulations using PM4Sand generally provided good estimates of total settlement of the structure. The numerical simulations also provided relatively comparable acceleration response in the soil beneath the structures and the ii acceleration response at the base and top of the structure. However, more variability between the measured and simulated excess pore pressure response in the liquefiable soils was noted. The research undertaken in this study shows that numerical simulations are generally able to capture important mechanisms due to liquefaction. In this study, a better response was obtained using the PM4Sand constitutive soil model when simulating ‘free-field’ conditions. However, it should be noted that this observation is based on comparisons against one centrifuge experiment and for the soil parameters adopted in this study.
