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.

Available in PDF, EPUB and Kindle. Book excerpt: Presented is the development of high-fidelity elastoplastic finite element simulation for earthquake soil-structure interaction problems. Part I presents the modeling and simulation systems for earthquake soil-structure interaction problems, Part II presents the high-fidelity modeling aspects of the systems, and Part III presents the high-performance aspects of the systems. Part I presents the modeling and simulation systems for earthquake soil-structure interaction (ESSI ) problems. The simulation system was named ESSI, which shares the same name with the target problem. The ESSI simulation system is based on the finite element analysis (FEA). Three features are presented as follows: (i) A domain-specific language (DSL) was extended in ESSI to facilitate the modeling of FEA. (ii) To reduce the simulation domain in an earthquake, a new interface of seismic input using wave deconvolution and domain reduction method is developed. (iii) To improve the availability of ESSI system, a remote desktop containing ESSI systems, preprocess and postprocess utilities is deployed on the cloud computing platform. The performance and cost of ESSI cloud computing services are discussed.Part II focuses on high-fidelity elastoplastic material modeling in ESSI system. To improve the earthquake-resistant design, the realistic modeling of soil stress-strain behavior plays a crucial role in the elastoplastic finite element analysis. Three features about the elastoplastic material modeling are presented as follows: (i) To simulate the realistic shear behavior unload cyclic loading, multi-surface plastic model is implemented to match the shear modulus reduction and damping properties. (ii) To represent the micro-structure of soil materials, the three-dimensional finite element formula of Cosserat elastoplasticity are developed and implemented. With the additional couple stress, researchers are able to control the free rotations on particles. The Cosserat elastoplastic models achieve mesh-independent plastic zones in the localization problems. (iii) To build trust in the developed elastoplastic materials, the constitutive algorithms are verified using prescribed solution forcing, Richardson extrapolation, and grid convergence index.Part III focuses on high-performance aspects of ESSI system, including coarse-grain parallelism and fine-grain parallelism. In coarse-grain parallelism, hardware-aware plastic domain decomposition (HAPDD) algorithm is developed for load balancing. Elastoplastic finite element simulation has two computation phases: solving elastoplastic material at Gauss points and solving systems of equations of all elements. HAPDD aims to balance the computation load of solving elastoplastic material. Metis/ParMetis and Scotch/PtScotch are used to adaptively repartition the computation graph. A parametric study is conducted to tune the partitioning kernel for the specific application code in earthquake soil-structure interaction. In fine-grain parallelism, a small tensor library is developed to accelerate the elastoplastic algorithms. While the conventional linear algebra optimizes the large-scale matrix operations, however, in elastoplastic algorithms, millions of small tensor algebra dominates the computation time. Explicit SIMD intrinsic functions are used to improve the tensor algebra performance.Based on the three parts above, the ESSI system was significantly improved in thisresearch in terms of simulation features and performance.

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.

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 excerpt: With the continued improvements in computing power and digital information availability, we are witnessing the increasing use of high-performance computers to enhance simulations for the forecasting of hazards, disasters, and responses. This major reference work summarizes the theories, analysis methods, and computational results of various earthquake simulations by the use of supercomputers. It covers simulations in the fields of seismology, physical geology, earthquake engineering — specifically the seismic response of structures — and the socioeconomic impact of post-earthquake recovery on cities and societies. Individual chapters address phenomena such as earthquake cycles and plate boundary behavior, tsunamis, structural response to strong ground motion, and post-disaster traffic flow and economic activity. The methods used for these simulations include finite element methods, discrete element methods, smoothed particle hydrodynamics, and multi-agent models, among others.The simulations included in this book provide an effective bird's-eye view of cutting-edge simulations enhanced with high-performance computing for earthquake occurrence, earthquake damage, and recovery from the damage, combining three of the major fields of earthquake studies: earth science, earthquake engineering, and disaster-mitigation-related social science. The book is suitable for advanced undergraduates, graduates, and researchers in these fields.
