The purpose of this project is to investigate the validity of seismic soil-foundation-structure interaction analysis of a typical California highway bridge structure subjected to near-fault ground motions. A three-dimensional nonlinear finite element model of Meloland Road Overcrossing was developed. The model included a combination of elements including shell elements for the bridge deck. The column and piles were modeled using frame elements. Abutment-backfill and ground soil were simulated using nonlinear springs. The complete bridge system was subjected to three-component recorded free-field earthquake motions. The resulting dynamic response of the bridge model was found to be in close agreement with motions recorded at various locations on the bridge. This validates the practical application and methodology of this project and may be used for evaluating the seismic response of other typical bridges.

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.

The book focuses on the use of inelastic analysis methods for the seismic assessment and design of bridges, for which the work carried out so far, albeit interesting and useful, is nevertheless clearly less than that for buildings. Although some valuable literature on the subject is currently available, the most advanced inelastic analysis methods that emerged during the last decade are currently found only in the specialised research-oriented literature, such as technical journals and conference proceedings. Hence the key objective of this book is two-fold, first to present all important methods belonging to the aforementioned category in a uniform and sufficient for their understanding and implementation length, and to provide also a critical perspective on them by including selected case-studies wherein more than one methods are applied to a specific bridge and by offering some critical comments on the limitations of the individual methods and on their relative efficiency. The book should be a valuable tool for both researchers and practicing engineers dealing with seismic design and assessment of bridges, by both making the methods and the analytical tools available for their implementation, and by assisting them to select the method that best suits the individual bridge projects that each engineer and/or researcher faces.
