The design of foundation of the building structure should be given prime attention because building foundation is in contact with the material i.e. soil which is highly complex, particulate, poly-phase, heterogeneous, and stress and strain level dependent. The real behavior of structure in contact with soil involves an interactive process beginning with the construction phase and ending with a state of balance within the structure and within the ground influenced by the structure. The analysis of such combined piled-raft foundation is very challenging because of complexities involved in the interaction between soil, pile, raft slab and structure. The interaction between the soil, foundation and the structure affects the demands (loads and displacements) imposed on structure, and the analysis of interaction between the pile, the raft and the soil of combined piled-raft foundation and upper structure can only be possible effectively by means of an advanced three-dimensional non-linear finite element technique or using a computer code based on advanced computational techniques in which proper models are incorporated to simulate soil behavior and soil-structure interaction.

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.

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.

Soil-structure-interaction (SSI) plays an important role in seismically-induced ground failure; however, the contribution is poorly understood and rarely considered in geotechnical engineering practice. Semi-empirical methodologies used in practice to evaluate ground failure solely consider demand from vertically propagating shear waves in the free field. Mounting evidence suggests this approach may significantly underpredict induced demand in soils below shallow foundations by neglecting SSI-induced stress contributions. Observations made during post-earthquake reconnaissance suggest that soils below low- to mid-rise structures supported on shallow foundations may be more susceptible to ground failure than soils in the corresponding free field. Recent physical and numerical modeling studies substantiate this evidence by demonstrating that SSI-induced stresses contribute to ground failure potential and may exacerbate the consequences of ground failure. Studies to date have centered on liquefaction-based (e.g. sand-like) ground failure; complementary studies on cyclic softening (e.g. clay-like) ground failure are not available. This research seeks to fill that knowledge gap by evaluating the SSI-induced seismic loading increment imparted by shallow foundations on fine-grained soils within the context of cyclic softening ground failure. The research is based on an analysis framework that utilizes elastic solutions to define SSI-induced stress demands beneath shallow foundations. The framework proposes a new demand parameter called the deviatoric strength ratio to quantify incremental stress demands under complex stress paths below footings. To substantiate the framework and provide empirical case history data on cyclic softening, the author performed a geotechnical centrifuge testing program at the Center for Geotechnical Modeling at the University of California Davis. The program consisted of two dynamic centrifuge tests incorporating structures founded on strip footings and bearing on fine grained soil. The structures incorporated a range of mass and stiffness properties at approximately the same bearing pressure to evaluate the influence of structure response on cyclic softening. Analysis results indicate a strong relationship between permanent foundation settlement or rotation and indices that represent spatially averaged cyclic strains in foundation soils when subjected to deviatoric stress demands from ground response and SSI.
