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.

Download or read book Deterministic Numerical Modeling of Soil Structure Interaction written by Stephane Grange and published by John Wiley & Sons. This book was released on 2021-12-22 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.

Book Synopsis Dynamic Soil-Structure-Soil-Interaction Analysis of Structures in Dense Urban Environments by : Katherine Carys Jones
Download or read book Dynamic Soil-Structure-Soil-Interaction Analysis of Structures in Dense Urban Environments written by Katherine Carys Jones and published by . This book was released on 2013 with total page 702 pages. Available in PDF, EPUB and Kindle. Book excerpt: Urban centers are increasingly becoming the locus of enterprise, innovation, and population. This pull toward the center of cities has steadily elevated the importance of these areas. Growth has necessarily spawned new construction. Consequently, modern buildings are often constructed alongside legacy structures, new deep basements are constructed alongside existing shallow foundations, and city blocks composed of a variety of building types result. The underlying soil, foundation, and superstructure of each of these buildings can interact and combine to yield unique seismic responses. Since the seminal work of researchers such as Luco and Contesse (1973) and Wong and Trifunac (1975), researchers have investigated the effects of soil-structure interaction (SSI). This phenomenon refers to the interaction between a single building, its foundation, and the underlying soil during a seismic event. However, as the trend toward urbanization continues, a shortcoming of this conventional SSI approach is that in reality, a structure will almost certainly be located near other structures in metropolitan areas. In this line of research, the interaction of multiple, adjacent buildings during a seismic event, a phenomenon known as structure-soil-structure interaction (SSSI), is investigated. This topic does not yet command the level of attention given to SSI. However, SSSI has the potential to be significantly detrimental or beneficial, depending on the configuration and dynamic properties of the buildings and their foundations in dense urban environments. It is important to understand SSSI effects so that earthquake engineers can make informed decisions about the design and construction of structures in increasingly dense urban areas. As part of a larger, multi-university National Science Foundation (NSF)-supported Network for Earthquake Engineering Simulation Research (NEESR) project, a series of centrifuge experiments were performed at the NEES-supported Center for Geotechnical Modeling (CGM) at the University of California, Davis. Each of these experiments examined aspects of SSI or SSSI through the use of nonlinear structural model buildings situated on different foundations that were supported on deep sand deposits. The centrifuge experiments created a suite of small-scale physical model "case histories" that provided "data" and insight that could be extended through calibrated numerical simulations. The results of the first three centrifuge experiments in the test series (i.e., Test-1, Test-2, and Test-3) were utilized in this dissertation. Numerical analyses are usually only performed for high-profile projects. The effort, expertise and resources required to calibrate and to perform detailed numerical simulations is often prohibitive for typical low- to mid-rise structures. There is a need for a more accessible numerical tool that both geotechnical and structural engineers can utilize to gain insight. In this research, the FLAC finite difference program (Itasca, 2005) with a fully nonlinear effective stress soil constitutive model was used to analyze the centrifuge test-generated "case histories." Test-1 and Test-2 examined SSI and SSSI effects of two moment-resisting frames (MRFs). Test-1 employed a solitary 3-story (prototype) MRF founded on shallow spread footings and a solitary 9-story (prototype) MRF founded on a deep basement (equivalent to 3-stories, prototype) to investigate SSI effects. In Test-2, the 3-story (prototype) and 9-story (prototype) MRFs were placed immediately adjacent to one another to examine SSSI effects. Kinematic interaction effects were primarily observed in these tests. Hence, Test-3 was designed to investigate inertial interaction effects. Three structures were included in Test-3: two MRFs founded on shallow spread footings and one elastic shear-wall structure on a mat foundation. Each of these structures was designed to maximize inertial interaction by: (1) matching the flexible base period of each structure to the soil column to induce resonance, and (2) optimizing structural properties to increase inertial interaction effects. One MRF was positioned alone at one end of the centrifuge model, a SSI condition, and the other MRF and the elastic shear-wall structure were positioned immediately adjacent to each other in the other end of the centrifuge model, a SSSI condition. The rich data set developed through the centrifuge experiments formed the basis of the initial FLAC analyses. A critical aspect of any seismic analysis is the constitutive model used to capture the soil response to cyclic loading. Several soil models were examined during an initial seismic site response analysis. Free-field data from sensors located within the centrifuge soil column were used to quantify the vertical propagation of ground motions through the soil profile. The best model for the dense (Dr = 80%), dry sand used in the centrifuge for Test-1 through Test-3 was a Mohr-Coulomb based model with hysteretic damping, UBCHYST (Naesgaard, 2011). Pseudo-acceleration response spectra and acceleration time histories at the base and at the free-field surface from the centrifuge and the numerical model were compared. The numerical simulations successfully captured the key aspects of the observed seismic site-response for both near-fault pulse-type motions and ordinary motions at a variety of intensities. After successfully capturing the free-field seismic site responses of Test-1 and Test-2, the dynamic responses of the structural models were examined. Each structure was modeled satisfactorily with a two-dimensional, plane-strain numerical model. Engineering design parameters (EDPs) were computed for key structural responses, including (1) transient peak roof drift, (2) residual roof drift, (3) transient peak displacement and (4) peak acceleration at the center of mass of the structure. Additionally, the acceleration time histories and pseudo-acceleration response spectra at the center of mass of the structure for each motion were examined. These metrics were used to compare the numerically estimated dynamic responses with those recorded in the centrifuge experiments. The dynamic response of the 3-story (prototype) MRF estimated with the numerical model was in close agreement with the observed experimental data for both the SSI (Test-1) and SSSI (Test-2) configurations. The more complicated 9-story (prototype) model exhibited greater sensitivity to numerical system inputs, including fixed-base fundamental period and applied structural Rayleigh damping. However, the majority of its recorded dynamic responses were well-matched by the numerical model. The resonant condition created in Test-3 proved challenging to model numerically. The two Test-3 conditions (i.e., SSI and SSSI) were analyzed separately. Significant inertial interaction, including rocking, was observed during the centrifuge test and in the post-processing of data; pseudo-acceleration responses three to five times those recorded in Test-1 and Test-2 were recorded. While the shapes of the pseudo-acceleration response spectra, periods of amplification, and time-histories were well-captured, the numerical model estimated significantly lower amplitudes of the responses for the structures than were observed during the centrifuge test. A sensitivity study was performed to evaluate the influence of several parameters, including (1) the shear wave velocity profile, (2) interface elements, (3) fixed-base fundamental period estimate, and (4) constitutive model parameters. Some of the relative lack of amplification in the numerical simulations was due to over damping in the constitutive model. This was addressed by altering the shear modulus and material damping curves for the soil directly beneath the structures' foundation elements. However, the primary reason for the lower amplitude estimated by the numerical model appeared to be due to the difficulty of capturing the seismic responses of structures in the resonant condition. Shifting the period of any component of the soil-structure system would necessarily have a significant impact on the dynamic response by shifting the system away from resonance. Despite this challenge, the numerical simulations yielded important insights. While the amplitudes of dynamic responses were underestimated for most of the ground motions, the changes in response of the 3-story (prototype) MRF between SSI and SSSI were captured. The elastic shear wall displayed similar behavior; while the spectral shapes were matched for most motions, the amplitudes estimated by the numerical simulations were consistently below those observed in the centrifuge. Comparison of overall change from low- to high-intensity motions or trends from SSI to SSSI could be captured with the model; however, the amplitudes of the responses were generally underestimated. This set of analyses highlighted the challenge of modeling a resonant condition. Additional work is needed to explore the characteristics of the centrifuge when intense input motions are used which are in resonance with the soil in the model. Finally, two prototypical structures were examined. The first, a 3-story MRF, was the model upon which the centrifuge 3-story (prototype) model was based (Ganuza, 2006). Both solitary (SSI) and adjacent (SSSI) configurations were considered for this prototypical 3-story MRF founded on a dense sand soil column. The dynamic responses of the MRF for the solitary (SSI) condition paralleled those observed in the centrifuge experiments. For the considered configurations of adjacent low-rise structures, SSSI effects were found to be either negligible or only slightly beneficial or detrimental for the five ground motions utilized for dynamic analysis. The other prototypical MRF, a 5-story structure, was a simplified version of a typical, medium-rise structure (Ganuza, 2006). The 5-story MRF exhibited dynamic responses consistent with previous work. Amplific.

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.

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.

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.
