Book Description
Soil-structure interaction (SSI) effects are relevant for the seismic analysis of tall buildings on shallow foundations since the dynamic behavior of structures is highly affected by the interaction between the superstructure and supporting soils. As part of earthquake-resistant designs of buildings, considering SSI effects in the analysis provides more realistic estimates of its performance during a seismic event, particularly when both the structure and soil undergo large demands that can compromise serviceability. Oversimplifications of structural or soil modeling in the analysis introduces variability and biases in the computed seismic response.

Book Description
Despite advances in the field of geotechnical earthquake engineering, earthquakes continue to cause loss of life and property in one part of the world or another. The Third International Conference on Soil Dynamics and Earthquake Engineering, Princeton University, Princeton, New Jersey, USA, 22nd to 24th June 1987, provided an opportunity for participants from all over the world to share their expertise to enhance the role of mechanics and other disciplines as they relate to earthquake engineering. The edited proceedings of the conference are published in four volumes. This volume covers: Soil Structure Interaction under Dynamic Loads, Vibration of Machine Foundations, and Base Isolation in Earthquake Engineering. With its companion volumes, it is hoped that it will contribute to the further development of techniques, methods and innovative approaches in soil dynamics and earthquake engineering.

Book Description
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.

Book Description
Dynamic Soil-structure interaction is one of the major topics in earthquake engineering and soil dynamics since it is closely related to the safety evaluation of many important engineering projects, such as nuclear power plants, to resist earthquakes. In dealing with the analysis of dynamic soil-structure interactions, one of the most difficult tasks is the modeling of unbounded media. To solve this problem, many numerical methods and techniques have been developed. This book summarizes the most recent developments and applications in the field of dynamic soil-structure interaction, both in China and Switzerland. An excellent book for scientists and engineers in civil engineering, structural engineering, geotechnical engineering and earthquake engineering.

Book Description
Current seismic regulations allow earthquake energy dissipation via inelastic behaviour of structures providing that collapse is avoided. Considering that this philosophy can negatively impact due to loss of function of critical structures, mitigation systems are currently being explored by researches. In the last decades a new concept for reducing structural response has emerged. By allowing soil plastic deformations and foundation lift-off, structural performance can be improved. However, more research is required in order to better understand this phenomenon. This thesis concerns an experimental investigation into the structural response of buildings allowed to uplift when subjected to near-source earthquakes considering nonlinear soil-foundation-structure-interaction (NSFSI). Considering that gravity cannot be neglected in scaled models allowed to uplift, a new modelling approach was developed to account for gravity effects. Based on this method, a small scale model of a low rise building was built. Inelastic behaviour of the superstructure was considered by means of replaceable plastic hinge components. To study the benefits of uplift and NSFSI on the structural response, 10 records of actual near-source earthquakes were considered and subsoil was simulated by means of sand in a box. The scaled model constructed using the modelling method developed in this research was validated and it was capable of simulating a more realistic uplift behaviour even at small excitations. The experimental results suggest that uplift is unavoidable and it can significantly reduce the response of the structure. When soil plastic deformation is considered, the response of the structure can be further reduced remaining practically elastic. In contrast, uplift can increase the absolute horizontal displacements of the structure when the supporting base is rigid but marginally increased when soil plastic deformations are permitted. Because of the impulsive loading of near-source earthquakes and soil plastic deformation of subsoil, permanent rotation of the footing was observed after the uplift.

Book Description
This monograph deals with the problem of dynamic behaviour and seismic response of structures which are designed and constructed in seismic regions. Extensive attention is given to description of measuring methods, methods of evaluation of results and determination of dynamic properties of structures. The questions of linear and non-linear seismic response are solved taking into account the peculiarities of stiffness and damping and the demands of proper seismic design and the protecting of structures against unfavourable seismic effects. There is detailed analysis of torsional sesimic effects on structures with asymmetrical disposition in plan, of the influence of higher axial forces on the seismic response and of the problems of soil-structure interaction. The experimental results are extensively documented, with graphs, tables, photographs and a keyword index. This volume will interest structural engineers, engineers-designers, geophysicists, mechanical and geotechnical engineers. It is intended to serve both readers already acquainted with problems of earthquake engineering and beginners in this field.
