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.

Doria 6, 95125 Catania, Italy Soil-Structure Interaction is a challenging multidisciplinary subject which covers several areas of Civil Engineering. Virtually every construction is connected to the ground and the interaction between the artefact and the foundation medium may affect considerably both the superstructure and the foundation soil. The Soil-Structure Interaction problem has become an important feature of Structural Engineering with the advent of massive constructions on soft soils such as nuclear power plants, concrete and earth dams. Buildings, bridges, tunnels and underground structures may also require particular attention to be given to the problems of Soil-Structure Interaction. Dynamic Soil-Structure Interaction is prominent in Earthquake Engineering problems. The complexity of the problem, due also to its multidisciplinary nature and to the fact of having to consider bounded and unbounded media of different mechanical characteristics, requires a numerical treatment for any application of engineering significance. The Boundary Element Method appears to be well suited to solve problems of Soil- Structure Interaction through its ability to discretize only the boundaries of complex and often unbounded geometries. Non-linear problems which often arise in Soil-Structure Interaction may also be treated advantageously by a judicious mix of Boundary and Finite Element discretizations.

Available in PDF, EPUB and Kindle. Book excerpt: This edited book provides discussion and presents results related to some "hot topics," all dealing with the soil-structure interaction. The book can be of interest to both scientists involved in academic studies of the problems addressed and for practitioners engaged in high-level design.Chapter I reports the investigation of non-stationary wave propagation in continuously inhomogeneous cylindrical elements (such as pipelines). New results obtained by numerical analysis of non-stationary wave propagation are presented. The cases studied comprise simulations of the propagations of both one-dimensional and two-dimensional non-stationary waves. Waves of the first type are supposed to propagate in continuously inhomogeneous, linearly viscoelastic cylinders, whereas waves of the second type propagate in continuously inhomogeneous elastic cylinders. The authors of this chapter apply an original research method consisting of the implementation of solutions to dynamic problems in the study of elastic and linearly viscoelastic piecewise homogeneous bodies.Chapter II outlines an analytical study of the propagation of different types of waves (plane, cylindrical, spherical) as well as of the waves' interaction with an element of Vibro-isolation (specifically, a three-layer plate). The author also presents the numerical results of the study of the distribution of the vibration accelerations in soil.Chapter III presents details on the analytical modeling of a bearing device for passive seismic isolation (friction-pendulum system). The behavior of the slider is identical to a motion of a particle constrained to slide on a spherical surface. The analytical model includes equations of motion, derived using the Lagrange formalism and constitutive equations of the sliding interface. The author presents the results of the numerical simulation of the response of the bearing device to a seismic event, assuming a constant value of the friction coefficient.Chapter IV proposes a discussion on the assessment of the load-carrying capacity of a metal-resin anchor and the determination of dependencies between parameters of supporting systems that include anchors. The solution to the problems addressed in this study involves an accurate analysis of the load transfer mechanisms between different system components. The proposed strategy requires the implementation of an algorithm aimed at the reconstruction of the analytical form of a function, provided its tabular form is available. The authors also formulate a theorem that postulates the existence of such representation applicable in a more general context.The research object in Chapter V is the formulation of the boundary value problems for circular and annular three-layer plates subjected to axisymmetric loading. The considered plates consist of three layers: two thin bearing layers and one filler layer, with a perfect bond, assumed for all interfaces. The definition of the stress-strain state in the plates presumes that the Kirchhoff's hypotheses regarding the bearing layers and the Timoshenko's hypothesis (i.e., linear distribution of the tangential displacements over the thickness) concerning the filler layer hold. The performed analyses take into account the characteristics of the elastic (Winkler) foundation. The authors provide the obtained analytical solutions to the formulated boundary value problems. Results obtained by numerical analysis of the stress and the strain distributions for plates supported by hinges on the contour are also presented.

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 2011-09 with total page 120 pages. Available in PDF, EPUB and Kindle. Book excerpt: Numerical assessment of soil structure interaction problems require heavy computational efforts because of the dynamic and iterative (nonlinear) nature of the problems. Furthermore, modeling soil-structure interaction may require finer meshes in order to get reliable results. Latest computing technologies must be utilized to achieve results in reasonable run times. This book focuses on development and implantation of a parallel dynamic finite element analysis method for numerical solution of soil-structure interaction problems. For this purpose first, an extensible parallel finite element analysis library was developed. Then this library was extended with algorithms that implement the parallel dynamic solution method. Parallel dynamic solution algorithm is based on Implicit Newmark integration algorithm. This algo- rithm was parallelized using MPI (Message Passing Interface). For numerical modeling of soil material an equivalent linear material model was used. Several tests were done to benchmark and demonstrate parallel performance of implemented algorithms.

Download or read book Reduced Order Modeling of Soil Structure Interaction Problems written by Elnaz Esmaeilzadeh Seylabi and published by . This book was released on 2016 with total page 176 pages. Available in PDF, EPUB and Kindle. Book excerpt: This dissertation is focused on creating the key ingredients of a numerical platform for reduced order modeling of soil structure interaction (SSI) problems. Specifically, a computer code is developed for forward simulation of wave propagation in the two-dimensional (plane-strain and axisymmetric) semi-infinite heterogeneous solid media. Perfectly matched layers (PMLs) are used for absorbing the outgoing waves. The computationally efficient symmetric hybrid PML formulation available for the plane-strain setting is extended to axisymmetric problems. The domain reduction method (DRM) is used for translation of the remote excitation within a PML-truncated medium. The methodologies are devised for using this finite element (FE) solver to (i) compute the soil impedance functions and (ii) the modified input motions (a.k.a. foundation input motion) of rigid and flexible interfaces embedded in heterogeneous half-spaces numerically. Existing semi-analytical solutions are used to verify these methods comprehensively. The verified framework is validated using data from a large-scale field test as well as centrifuge experiments. In order to demonstrate the framework's application: (i) the impedance functions and kinematic interaction transfer functions (KITFs) of a number of SSI problems---for which existing analytical solutions are limited---are computed; and (ii) the reduced order model of a buried structure in an elastic half-space is constructed. In order to avoid integro-differential equations, stable discrete-time filters are used for devising time-domain representations of the computed soil impedance matrix. The dynamic response of the resulting spatio-temporal reduced order model is compared against those obtained from solving the same problem using the direct modeling approach, and excellent agreement is observed.

This book was released on 2012-12-06 with total page 446 pages. Available in PDF, EPUB and Kindle. Book excerpt: For the last couple of decades it has been recognized that the foundation material on which a structure is constructed may interact dynamically with the structure during its response to dynamic excitation to the extent that the stresses and deflections in the system are modified from the values that would have been developed if it had been on a rigid foundation. This phenomenon is examined in detail in the book. The basic solutions are examined in time and frequency domains and finite element and boundary element solutions compared. Experimental investigations aimed at correlation and verification with theory are described in detail. A wide variety of SSI problems may be formulated and solved approximately using simplified models in lieu of rigorous procedures; the book gives a good overview of these methods. A feature which often lacks in other texts on the subject is the way in which dynamic behavior of soil can be modeled. Two contributors have addressed this problem from the computational and physical characterization viewpoints. The book illustrates practical areas with the analysis of tunnel linings and stiffness and damping of pile groups. Finally, design code provisions and derivation of design input motions complete this thorough overview of SSI in conventional engineering practice. Taken in its entirety the book, authored by fifteen well known experts, gives an in-depth review of soil-structure interaction across a broad spectrum of aspects usually not covered in a single volume. It should be a readily useable reference for the research worker as well as the advance level practitioner. (abstract) This book treats the dynamic soil-structure interaction phenomenon across a broad spectrum of aspects ranging from basic theory, simplified and rigorous solution techniques and their comparisons as well as successes in predicting experimentally recorded measurements. Dynamic soil behavior and practical problems are given thorough coverage. It is intended to serve both as a readily understandable reference work for the researcher and the advanced-level practitioner.
