Advances in Cable-Supported Bridges


Book Description

Cable-supported bridges are known for their visual elegance, aesthetic appeal and ability to link long spans. The extent of issues of concern associated with these structures is commensurate with their size and vast scale. Significant advances in the technology of assessment, design, construction and maintenance of cable-supported bridges have been achieved in the past few years, due to increasing awareness, collaboration and information exchange.This book contains selected papers on cable-supported bridges as presented at the 5th International Cable-Supported Bridge Operators' Conference, held in New York City on August 28-29, 2006. It includes papers by leading international bridge engineers. Presenting state-of-the-art material, the book is an authoritative account on the developments in the field, this volume forms essential reading to anyone working on cable-supported bridges.

Cable Supported Bridges


Book Description

Fourteen years on from its last edition, Cable Supported Bridges: Concept and Design, Third Edition, has been significantly updated with new material and brand new imagery throughout. Since the appearance of the second edition, the focus on the dynamic response of cable supported bridges has increased, and this development is recognised with two new chapters, covering bridge aerodynamics and other dynamic topics such as pedestrian-induced vibrations and bridge monitoring. This book concentrates on the synthesis of cable supported bridges, suspension as well as cable stayed, covering both design and construction aspects. The emphasis is on the conceptual design phase where the main features of the bridge will be determined. Based on comparative analyses with relatively simple mathematical expressions, the different structural forms are quantified and preliminary optimization demonstrated. This provides a first estimate on dimensions of the main load carrying elements to give in an initial input for mathematical computer models used in the detailed design phase. Key features: Describes evolution and trends within the design and construction of cable supported bridges Describes the response of structures to dynamic actions that have attracted growing attention in recent years Highlights features of the different structural components and their interaction in the entire structural system Presents simple mathematical expressions to give a first estimate on dimensions of the load carrying elements to be used in an initial computer input This comprehensive coverage of the design and construction of cable supported bridges provides an invaluable, tried and tested resource for academics and engineers.




Cable Stayed, Supported And Suspension Bridges


Book Description

This book comprises about 50 scientific papers presented by academicians, leading engineers, consultants and students from various disciplines of Bridge Engineering Research and Development from India and abroad. The deliberations at the International Conference covered a wide spectrum of research and development activities in the field of suspension and cable stayed bridges.




Cable Vibrations in Cable-stayed Bridges


Book Description

The present book provides a comprehensive survey on the governing phenomena of cable vibration, both associated with direct action of wind and rain: buffeting, vortex-shedding, wake effects, rain-wind vibration; and resulting from the indirect excitation through anchorage oscillation: external and parametric excitation. Methodologies for assessment of the effects of those phenomena are presented and illustrated by practical examples. Control of cable vibrations is then discussed and state-of-art results on the design of passive control devices are presented.




Wind Effects on Cable-Supported Bridges


Book Description

As an in-depth guide to understanding wind effects on cable-supported bridges, this book uses analytical, numerical and experimental methods to give readers a fundamental and practical understanding of the subject matter. It is structured to systemically move from introductory areas through to advanced topics currently being developed from research work. The author concludes with the application of the theory covered to real-world examples, enabling readers to apply their knowledge. The author provides background material, covering areas such as wind climate, cable-supported bridges, wind-induced damage, and the history of bridge wind engineering. Wind characteristics in atmospheric boundary layer, mean wind load and aerostatic instability, wind-induced vibration and aerodynamic instability, and wind tunnel testing are then described as the fundamentals of the subject. State-of-the-art contributions include rain-wind-induced cable vibration, wind-vehicle-bridge interaction, wind-induced vibration control, wind and structural health monitoring, fatigue analysis, reliability analysis, typhoon wind simulation, non-stationary and nonlinear buffeting response. Lastly, the theory is applied to the actual long-span cable-supported bridges. Structured in an easy-to-follow way, covering the topic from the fundamentals right through to the state-of-the-art Describes advanced topics such as wind and structural health monitoring and non-stationary and nonlinear buffeting response Gives a comprehensive description of various methods including CFD simulations of bridge and vehicle loading Uses two projects with which the author has worked extensively, Stonecutters cable-stayed bridge and Tsing Ma suspension bridge, as worked examples, giving readers a practical understanding




Multi-Span Large Bridges


Book Description

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 undoubted




Basic Principles of Cable Supported Bridges


Book Description

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.
