The intention of fib Bulletin 32 is to present guidelines for the design of footbridges as well as bridges accommodating cyclists and bridleways (equestrian paths). The need for these guidelines comes from the fact that structural engineers designing footbridges currently have to spend considerable time and energy collecting information from numerous documents, codes and recommendations to make design decisions. There seems to be no international document dedicated solely to the design of footbridges. These guidelines attempt to provide a concentrated source of information regarding all design issues specific to footbridges. It is meant to be a 'liberal' document in the sense that it promotes new, innovative and bold yet prudent designs by sharing the experience of the authors, summarizing specifications given in codes, and presenting a collection of examples of well-designed structures or structural details from around the world. It is not intended to be an international code that specifies limits and admissible values, thus encouraging timid, conservative designs that are repetitions of approved and tested designs. Indeed, it may be the very fact that no international code exists specifically for footbridges that encourages the wide variety of footbridge designs found today. It should be noted that numerous guidelines, codes and books have been published on bridge design in general. Information given in those publications that is also applicable to footbridges is not repeated in Bulletin 32. The chapters of these guidelines all follow the same pattern: an introduction to the subject, general guidelines as well as do's and don'ts; a summary of information found in existing international codes, recommendations, experience of the authors, and built examples with comparison and comments on this information; examples. Plenty of illustrations and photographs help to visualize the themes of this work. The last chapter, 'Case Studies', contains footbridges each with a short summary of main structural data and references for further reading.

The need for large-scale bridges is constantly growing due to the enormous infrastructure development around the world. Since the 1970s many of them have been cable-stayed bridges. In 1975 the largest span length was 404 m, in 1995 it increased to 856 m, and today it is 1104 m. Thus the economically efficient range of cable-stayed bridges is tending to move towards even larger spans, and cable-stayed bridges are increasingly the focus of interest worldwide. This book describes the fundamentals of design analysis, fabrication and construction, in which the author refers to 250 built examples to illustrate all aspects. International or national codes and technical regulations are referred to only as examples, such as bridges that were designed to German DIN, Eurocode, AASHTO, British Standards. The chapters on cables and erection are a major focus of this work as they represent the most important difference from other types of bridges. The examples were chosen from the bridges in which the author was personally involved, or where the consulting engineers, Leonhardt, Andrä and Partners (LAP), participated significantly. Other bridges are included for their special structural characteristics or their record span lengths. The most important design engineers are also presented. Note: The lecture videos which are attached to the print book on DVD are not part of the e-book.

These Design Guidelines have been developed to promote a uniform understanding of the state of practice in designing Arch, Cable-Stayed and Suspension Bridges. The provisions have been developed and formatted to supplement the AASHTO LRFD Bridge Design Specifications. The guidelines are, thus, presented in specifications-like language with supporting commentary to facilitate adaptation into project specific criteria where bridge owners deem applicable. Amongst cited references from the literature, national and international specifications, are reports on several investigations that were conducted as a part of developing these Guidelines including - review of HL-93 live load effects for designing long span structures, initial assessment of aerodynamic stability and bridge users' comfort criteria, adaptation of the FHWA-TS-80-205 interaction equations for slender plate buckling as an extension of the AASHTO LRFD provisions, and other issues. Appendices to the Guidelines contain selected design topics deemed of immediate application to the readers covering the arch, cable-stayed, and suspension bridge types; general design process; soil-structure interaction; and bridge health monitoring.

Addressed to designers and even more so to owners and project managers, this part is meant as a guide to an efficient selection of designers and contractors, and to the preparation of fair contracts providing high quality at reasonable cost. Clearly, a good design must be paid for at its real cost; economising on the design cost can be extremely counterproductive for the owner when considering the final whole-life cost of the project. In addition, it was considered very important to address the designer’s responsibilities and relations with other participants in large projects, and finally design philosophy itself. Part 2 – Design and construction aspects This more technical part is mainly addressed to bridge designers and devoted to a systematic analysis of structural and constructional bridge concepts. Considering the importance of erection techniques in the development of bridge design, this second part of the guide starts by a description of the different construction methods, their advantages and draw-backs, their particularities and, of course, by defining the domain of their most efficient applications. Another main chapter is devoted to the proper design of cross-sections. And finally, a third main chapter deals in detail with the influence of construction techniques on design.

This fib Recommendation gives technical guidelines regarding design, testing, acceptance, installation, qualification, inspection and maintenance of stay cable systems using prestressing steels (strands, wires or bars) as tensile elements, which can be applied internationally. This Recommendation is applicable for cable-stayed bridges and other suspended structures such as roofs. It may also be used for hangers in arch structures and as suspension cables, as appropriate. This Recommendations has been formulated by an international working group comprising more than 20 experts from administrative authorities, universities, laboratories, owners, structural designers, suppliers of prestressing steels and stay cable suppliers. The text has been written to cover best construction practices around the world, and to provide material specifications that are considered to be the most advanced available at the time of preparing this text. For ease of use (for client, designer and cable supplier), the complex content has been arranged thematically according to the system components into chapters focusing on performance characteristics, requirements and acceptance criteria. Requirements and comments have been specified for all parties involved in design and construction in order to aim for a uniform and high quality and durability. The interfaces to the structural designer are highlighted. The essential subjects are: Design and detailing of stay cables including saddles and damping devices Durability requirements and corrosion protection systems Requirements for the materials Testing requirements for the stay cables Installation, tolerances, qualification of companies and personnel Inspection, maintenance and repair. This Recommendation does not cover the technology of stay cables whose tensile elements are ropes, locked-coil cables, etc. or which consist of composite materials. Nevertheless, in many cases the specified performance criteria may also be applicable to these systems, although numerical values given for the acceptance criteria may need to be adjusted. For these systems it has been difficult to provide multiple protective layers similar to those specified for stay cables made from prestressing steel and therefore, the quality of corrosion protection may not be equivalent. While extradosed cables have similarities with stay cables, generally agreed design and system acceptance criteria are not yet available and therefore, this type of cable is not covered.

This book presents a brief design approach for cable-supported bridges based on experiences from past projects, both domestic and international, that were shared by experts in bridge engineering. The specifications outlined in the book are adopted in the design of several cable-stayed and extradosed bridges in India and abroad. These specifications are in conformance with the global best practices. In addition, reference literature has been consulted during the compilation of various sections of the book. In this endeavor, the author sought suggestions and collective guidance from some eminent specialists in cable-supported bridges from the USA, Europe and Asia in order to provide a glimpse of practices across the globe. In this book, the author has attempted to highlight the basic principles of cable supported bridges and the same should be used only as a guideline for design. It is believed that the reader would have acquired sufficient knowledge of analysis and design of complex bridges before going through this book. Lastly, brief case studies of two notable Indian bridges; the Second Vivekananda Extradosed (Nivedita) Bridge and Burdwan Cable Stayed Bridge are provided. While the former is an example of extradosed structure for Hooghly River crossing, the latter is a three-pylon (first time in India) cable stayed bridge over railway tracks. These examples will elucidate the purpose of this book and make it useful to young & practicing bridge engineers.
