Book excerpt: The influence of nonlinear soil-foundation-structure interaction (SFSI) on the performance of multi-storey buildings during earthquake events has become increasingly important in earthquake resistant design. For buildings on shallow foundations, SFSI refers to nonlinear geometric effects associated with uplift of the foundation from the supporting soil as well as nonlinear soil deformation effects. These effects can potentially be beneficial for structural performance, reducing forces transmitted from ground shaking to the structure. However, there is also the potential consequence of residual settlement and rotation of the foundation. This Thesis investigates the influence of SFSI in the performance of multi-storey buildings on shallow foundations through earthquake observations, experimental testing, and development of spring-bed numerical models that can be incorporated into integrated earthquake resistant design procedures. Observations were made following the 22 February 2011 Christchurch Earthquake in New Zealand of a number of multi-storey buildings on shallow foundations that performed satisfactorily. This was predominantly the case in areas where shallow foundations, typically large raft foundations, were founded on competent gravel and where there was no significant manifestation of liquefaction at the ground surface. The properties of these buildings and the soils they are founded on directed experimental work that was conducted to investigate the mechanisms by which SFSI may have influenced the behaviour of these types of structure-foundation systems. Centrifuge experiments were undertaken at the University of Dundee, Scotland using a range of structure-foundation models and a layer of dense cohesionless soil to simulate the situation in Christchurch where multi-storey buildings on shallow foundations performed well. Three equivalent single degree of freedom (SDOF) models representing 3, 5, and 7 storey buildings with identical large raft foundations were subjected to a range of dynamic Ricker wavelet excitations and Christchurch Earthquake records to investigate the influence of SFSI on the response of the equivalent buildings. The experimental results show that nonlinear SFSI has a significant influence on structural response and overall foundation deformations, even though the large raft foundations on competent soil meant that there was a significant reserve of bearing capacity available and nonlinear deformations may have been considered to have had minimal effect. Uplift of the foundation from the supporting soil was observed across a wide range of input motion amplitudes and was particularly significant as the amplitude of motion increased. Permanent soil deformation represented by foundation settlement and residual rotation was also observed but mainly for the larger input motions. However, the absolute extent of uplift and permanent soil deformation was very small compared to the size of the foundation meaning the serviceability of the building would still likely be maintained during large earthquake events. Even so, the small extent of SFSI resulted in attenuation of the response of the structure as the equivalent period of vibration was lengthened and the equivalent damping in the system increased. The experimental work undertaken was used to validate and enhance numerical modelling techniques that are simple yet sophisticated and promote interaction between geotechnical and structural specialists involved in the design of multi-storey buildings. Spring-bed modelling techniques were utilised as they provide a balance between ease of use, and thus ease of interaction with structural specialists who have these techniques readily available in practice, and theoretically rigorous solutions. Fixed base and elastic spring-bed models showed they were unable to capture the behaviour of the structure-foundation models tested in the centrifuge experiments. SFSI spring-bed models were able to more accurately capture the behaviour but recommendations were proposed for the parameters used to define the springs so that the numerical models closely matched experimental results. From the spring-bed modelling and results of centrifuge experiments, an equivalent linear design procedure was proposed along with a procedure and recommendations for the implementation of nonlinear SFSI spring-bed models in practice. The combination of earthquake observations, experimental testing, and simplified numerical analysis has shown how SFSI is influential in the earthquake performance of multi-storey buildings on shallow foundations and should be incorporated into earthquake resistant design of these structures.

Available in PDF, EPUB and Kindle. Book excerpt: Seismic Performance of Soil-Foundation-Structure Systems presents invited papers presented at the international workshop (University of Auckland, New Zealand, 21-22 November 2016). This international workshop brought together outstanding work in earthquake engineering that embraces a holistic consideration of soilfoundation-structure systems. For example, the diversity of papers in this volume is represented by contributions from the fields of shallow foundation in liquefiable soil, spatially distributed lifelines, bridges, clustered structures (see photo on front cover), sea floor seismic motion, multi-axial ground excitation, deep foundations, soil-foundation-structurefluid interaction, liquefaction-induced settlement and uplift with SFSI. A fundamental knowledge gap is manifested by the isolated manner geotechnical and structural engineers work. A holistic consideration of soil-foundation-structures systems is only possible if civil engineers work collaboratively to the mutual benefit of all disciplines. Another gap occurs by the retarded application of up-to-date research findings in engineering design practices. Seismic Performance of Soil-Foundation-Structure Systems is the outcome from the recognized need to close this gap, since it has been observed that a considerable delay exists between published research findings and application of the principles revealed by the research. Seismic Performance of Soil-Foundation-Structure Systems will be helpful in developing more understanding of the complex nature of responses these systems present under strong earthquakes, and will assist engineers in closing the gaps identified above.

This book was released on 2013 with total page 460 pages. Available in PDF, EPUB and Kindle. Book excerpt: The interactions between a structure, its foundation, and the surrounding soil during an earthquake are referred to as soil-foundation-structure interaction (SFSI). The interactions between multiple structures, and their foundations, through the surrounding soil are collectively known as structure-soil-structure interaction (SSSI). Modern design codes in use in the United States, and abroad, provide guidance for considering SFSI during the seismic design of structural systems. However, these same codes do not provide any guidance for considering SSSI. This situation is a direct result of the current paucity of research into the effects of SSSI on structural performance. This dissertation describes the results of four centrifuge experiments designed to study the influence of SSSI on the seismic performance of building-foundation systems. Following these experiments, numerical models were developed and their efficiency at reproducing measured response evaluated. The experimental program involved two pairs of tests. During Test-1 and Test-2, the SFSI and SSSI-influenced responses of two three-dimensional inelastic frame structures were recorded. During Test-3 and Test-4, the interactions between an inelastic frame structure and an elastic rocking wall arranged in a variety of orientations were recorded. In each of the pair of test series, one configuration was devoted to the evaluation of the response of the model frame structures far from any neighboring structure. Ultimately, the experimental results demonstrate that when structures are placed next to each other, the seismic demands in inelastic frame structures can increase. As such, seismic structural performance may be negatively impacted by SSSI. The tests reveal that footings of buildings placed nearest to other buildings can be physically restrained when loaded towards the other building -- a physical mechanism that had not previously been observed. This asymmetrical physical restraint resulted in a stiffened hysteretic response of footings nearest to adjacent buildings and nominal increases in seismic demands to superstructure elements. It is also demonstrated that wave-based analytical solutions to the SSSI problem alone are not adequate for modeling the interactions between building-foundation systems with highly nonlinear foundation responses. During the numerical phase of this research, available tools for modeling SFSI effects (i.e., absent the effects of neighboring structures) in OpenSees were first refined. The shallowFoundationGen command was redeveloped to give the user greater flexibility. Subsequently, it was demonstrated that the updated modeling technique provides an adequate means to model the experimentally observed coupling of the vertical footing force and overturning moment load combinations for shallow foundations attached to inelastic frame structures. Finally, an available methodology for modeling wave-based SSSI effects was implemented in OpenSees and its capability to predict the experimentally measured seismic demands of an SSSI-influenced inelastic structure was evaluated. Ultimately, it is concluded that the use of foundation-to-foundation connection springs, which are based on wave-based solutions, is insufficient for capturing the seismic response of adjacent structures with highly nonlinear individual SFSI responses.
Book Synopsis Performance Based Aseismic Design of Shallow Foundations by : Jeremy Toh
Download or read book Performance Based Aseismic Design of Shallow Foundations written by Jeremy Toh and published by LAP Lambert Academic Publishing. This book was released on 2010-07 with total page 332 pages. Available in PDF, EPUB and Kindle. Book excerpt: State of the art understanding of the seismic behaviour of shallow foundations has advanced rapidly in recent years, yet current design practice does not account for these advances. The idea that shallow foundation bearing failure should not occur during an earthquake is not in line with other areas of earthquake engineering, where performance based design is widely accepted. The macro-element investigated in this study is a simple tool that can model complex dynamic soil-structure interaction beneath a shallow foundation. A detailed account of macro-element theory and behaviour is given and a computer code, written for use with the MATLAB software, is included. Insights are made into the usefulness of the macro-element in routine design, the trade-off between actions and permanent displacements of the foundation and superstructure, and the way that conventional geotechnical conservatism does not apply in performance based design. This book will be of interest to academics and practitioners involved in earthquake engineering. It will be of particular value to those working in the areas of performance based design and soil-foundation-structure interaction.

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: Performance-Based Seismic Design (PBSD) is a structural design methodology that has become more common in urban centers around the world, particularly for the design of high-rise buildings. The primary benefit of PBSD is that it substantiates exceptions to prescribed code requirements, such as height limits applied to specific structural systems, and allows project teams to demonstrate higher performance levels for structures during a seismic event.However, the methodology also involves significantly more effort in the analysis and design stages, with verification of building performance required at multiple seismic demand levels using Nonlinear Response History Analysis (NRHA). The design process also requires substantial knowledge of overall building performance and analytical modeling, in order to proportion and detail structural systems to meet specific performance objectives.This CTBUH Technical Guide provides structural engineers, developers, and contractors with a general understanding of the PBSD process by presenting case studies that demonstrate the issues commonly encountered when using the methodology, along with their corresponding solutions. The guide also provides references to the latest industry guidelines, as applied in the western United States, with the goal of disseminating these methods to an international audience for the advancement and expansion of PBSD principles worldwide.
