This research project, "Dynamic Bridge Substructure Evaluation and Monitoring," was sponsored by the Federal Highway Administration (FHWA) under contract number DTFH61-96- C-00030. The research was funded to investigate the possibility that by measuring and modeling the dynamic response characteristics of a bridge substructure, one could determine the condition and safety of the substructure and identify its foundation type (shallow or deep). Determination of bridge foundation conditions with this approach may be applied to quantify losses in foundation stiffness caused by earthquake, scour, and impact events. Identification of bridge foundation type may be employed to estimate bridge stability and vulnerability under dead and live load ratings, particularly for unknown bridge foundations. Chapter 2 introduces the research project scope and presents the results of a literature review of related topics. Chapter 3 describes the bridges in Texas that were selected for modal vibration tests during the research. Three bridges and four substructures were selected to provide footing (shallow), pile cap on piles (deep), and piles (deep) foundation types to investigate the type of foundation. Chapter 4 presents the modal vibration testing program, looking at instrumentation and field test procedures used to measure the vibration responses of the bridges. Of particular interest is that selected piles of two bridge bents were able to be tested in a sound, undamaged state initially, and then as selected piles were first excavated and ultimately broken, to simulate scour and earthquake damage events, respectively. Chapter 5 details modal vibration data processing and analyses performed on the four tested bridge substructures for the three bridges. Example time, frequency spectra, and modal transfer function (TF) data are presented for the bridge substructures and sound, excavated, and broken pile states. The TFs were found to show increased flexibility (lower stiffness) for substructures as they were excavated and ultimately broken. However, comparisons of modal TF data for two similar bridges and substructures with shallow and deep (footing and pile cap on piles) foundations did not show promise for only experimental data indicating shallow versus deep bridge foundations. The possibility of determining substructure damage or foundation type, or both, using structural modeling and structural parameter estimation techniques to obtain so-called super-spring elements was extensively researched as discussed in chapter 6. Unfortunately, the outcome of the structural parameter estimation analyses was that the damage states could not be predicted reliably, nor could the foundation type be determined.

Relevant advances have been accomplished by the scientific community and engineering profession in the design, assessment, monitoring, maintenance, and management of sustainable and resilient bridge structures and infrastructures. These advances have been presented and discussed at The Sixth International Conference on Bridge Maintenance, Safety And Management (IABMAS 2012), held in Stresa, Italy, from 8 to 11 July 2012 (http://www.iabmas2012.org). IABMAS 2012 has been organised on behalf of the International Association for Bridge Maintenance And Safety (IABMAS) under the auspices of Politecnico di Milano. This book collects the extended versions of selected papers presented at IABMAS 2012 and invited papers originally published in a Special Issue of Structure and Infrastructure Engineering. These papers provide significant contributions to the process of making more rational decisions in bridge design, assessment, monitoring and maintenance. The editors would like to thank the authors for their contributions and hope that this collection of papers will represent a valuable reference for scientific research and engineering applications in the fields of design, assessment, monitoring, and maintenance of bridges and infrastructure networks.

Bridges play important role in modern infrastructural system. This book provides an up-to-date overview of the field of bridge engineering, as well as the recent significant contributions to the process of making rational decisions in bridge design, assessment and monitoring and resources optimization deployment for the purpose of enhancing the welfare of society. Tang specifies the purposes and requirements of the conceptual bridge design, considering bridge types, basic elements, structural systems and load conditions. Cremona and Poulin propose an assessment procedure for existing bridges. Kallias et al. develop a framework for the performance assessment of metallic bridges under atmospheric exposure by integrating coating deterioration and corrosion modelling. Soriano et al. employ a simplified approach to estimate the maximum traffic load effect on a highway bridge and compare the results with other approaches based on on-site weigh-in-motion data. Akiyama et al. propose a method for reliability-based durability design and service life assessment of reinforced concrete deck slab of jetty structures. Chen et al. propose a meso-scale model to simulate the uniform and pitting corrosion of rebar in concrete and to obtain the crack patterns of the concrete with different rebar arrangements. Ruan et al. present a traffic load model for long span multi-pylon cable- stayed bridges. Khuc and Catbas implement a non-target vision- based method for the measurement of both static and dynamic displacements time histories. Finally, Cruz presents the career of the outstanding bridge engineer Edgar Cardoso in the fields of bridge design and experimental analysis. The book serves as a valuable reference to all concerned with bridge structure and infrastructure systems, including students, researchers, engineers, consultants and contractors from all areas sections of bridge engineering. The chapters originally published as a special issue in Structure and Infrastructure Engineering.

Structural health monitoring (SHM) uses one or more in situ sensing systems placed in or around a structure, providing real-time evaluation of its performance and ultimately preventing structural failure. Although most commonly used in civil engineering, such as in roads, bridges, and dams, SHM is now finding applications in other engineering envir
