Examining the fundamental differences between design and analysis, Robert Benaim explores the close relationship between aesthetic and technical creativity and the importance of the intuitive, more imaginative qualities of design that every designer should employ when designing a structure. Aiding designers of concrete bridges in developing an intuitive understanding of structural action, this book encourages innovation and the development of engineering architecture. Simple, relevant calculation techniques that should precede any detailed analysis are summarized. Construction methods used to build concrete bridge decks and substructures are detailed and direct guidance on the choice and the sizing of different types of concrete bridge deck is given. In addition guidance is provided on solving recurring difficult problems of detailed design and realistic examples of the design process are provided. This book enables concrete bridge designers to broaden their scope in design and provides an analysis of the necessary calculations and methods.

By looking at how slender concrete deck is used in the design of suspension and cable stayed structures, Stress Ribbon and Cable-supported Pedestrian Bridges highlights their characteristic feature: their rigidity, which is mainly given by the tension stiffness of prestressed concrete decking so much so that movement caused by pedestrians or wind does not register as discomfort by its users. Illustrated throughout, this book provides examples of outstanding structures, including bridges designed by the author, which have been recently completed.

Throughout the last decades, the increasing development of the urban metropolis and the need to establish fundamental infrastructure networks, promoted the development of important projects worldwide and several Multi-Span Large Bridges have been erected. Certainly, many more will be erected in the next decades. This international context undoubtedly justifies the first International Conference on Multi-Span Large Bridges. The Multi-Span Large Bridges book contains the keynote lectures and the extended abstracts of selected papers presented at the Multi-Span Large Bridges International Conference (MSLB2015), organized by the Faculty of Engineering of the University of Porto, in cooperation with IST (Lisbon), University of Minho and LNEC, held in Porto, Portugal, from 1st to 3rd July, 2015. The most relevant themes covered in the book are: Landmark Projects, Conceptual Design, Innovative Construction Methods, Special Foundations and Geotechnical Site Investigations, Life Cycle, Monitoring, Maintenance & Management, Incidents and Accidents, New Materials and Special Devices, Extreme Loads, Rehabilitation, Safety and Serviceability, and Structural Analysis. The Multi-Span Large Bridges book shares the knowledge of several world experts, contains the description of relevant experiences and reports state-of-art achievements which, definitely, will be invaluable to bridge engineers, structural engineers and scientists.

The design of structures in general, and prestressed concrete structures in particular, requires considerably more information than is contained in building codes. A sound understanding of structural behaviour at all stages of loading is essential. This textbook presents a detailed description and explanation of the behaviour of prestressed concrete members and structures both at service loads and at ultimate loads and, in doing so, provide a comprehensive and up-to-date guide to structural design. Much of the text is based on first principles and relies only on the principles of mechanics and the properties of concrete and steel, with numerous worked examples. However, where the design requirements are code specific, this book refers to the provisions of Eurocode 2: Design of Concrete Structures and, where possible, the notation is the same as in Eurocode 2. A parallel volume is written to the Australian Standard for Concrete Structures AS3600-2009. The text runs from an introduction to the fundamentals to in-depth treatments of more advanced topics in modern prestressed concrete structures. It suits senior undergraduate and graduate students and also practising engineers who want comprehensive introduction to the design of prestressed concrete structures. It retains the clear and concise explanations and the easy-to-read style of the first edition, but the content has been extensively re-organised and considerably expanded and updated. New chapters cover design procedures, actions and loads; prestressing systems and construction requirements; connections and detailing; and design concepts for prestressed concrete bridges. The topic of serviceability is developed extensively throughout. All the authors have been researching and teaching the behaviour and design of prestressed concrete structures for over thirty-five years and the proposed new edition of the book reflects this wealth of experience. The work has also gained much from Professor Gilbert active and long-time involvement in the development of standards for concrete buildings and concrete bridges.

Simple design, low life cycle costs, and fast, easy construction are just a few of the reasons that make prestressed concrete attractive for use in bridges, water and wastewater storage tanks, ocean dock construction, flooring, and more. Prestressed Concrete covers the fundamentals of prestressing, systems of prestressing, losses, the ultimate strength of sections in flexure, shear and torsion, anchorage zone stresses, limit state concepts and holistic design of prestressed concrete elements. The book also provides information on design of determinate structures and indeterminate structures (beams and frames) inclusive of cable profiling. It discusses special structures like pipes, water tanks, etc. and the behavior of composite structures such as precast prestressed concrete beams cast- in-situ R.C. slab, along with its design provisions. Prestressed Concrete is a valuable guide for practicing engineers, students, and researchers.

This work was commissioned by the Highways Agency to produce guidance for bridge designers by addressing the thermally induced soil/structure integration problem created by environmental changes of temperature and the associated cyclical displacements imposed on the granular backfill to the bridge abutments. It develops a better theoretical understanding of the cyclic performance, in particular the strain racheting in the backfill soil when in contact with a stiff structure. It also identifies the governing soil parameters and examines their influence in the interaction problem, develops numerical modelling procedures to predict interactive soil behaviour, and identifies and quantifies the controlling features of bridge structures relevant to the interaction problem.

Design, rehabilitate, and maintain modern highway bridges. From steel and reinforced concrete design, to highway layout and basic geometrics, to geotechnical engineering and hydraulics, Demetrios E. Tonia's Bridge Engineering: Design, Rehabilitation, and Maintenance of Modern Highway Bridges fully integrates the resources you need to master the entire bridge-design process. Written with unusual clarity--and packed with timely design examples and case studies plus eye-opening sidebars and graphics--it shows you how to: understand bridge structures, functions, types, and applications; design superstructures and substructures for maximum maintainability; design highway components--approach pavements and slabs, structure geometrics and elevations, roadway alignments, and more; kick off the project--from funding to site surveying and coring; manage the design process--contract documents, reports, plans, client interactions, and more; manage the bridge itself--from creating a structure inventory to extending GIS and CADD functionality.
