As bridges spans get longer, lighter and more slender, aerodynamic loads become a matter of serious study. This volume of proceedings reflect the co-operation between civil and mechanical engineering and meteorology in this field.

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.

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

Physical models have been, and continue to be used by engineers when faced with unprecedented challenges, when engineering science has been inadequate or even non-existent, and in any other situation when engineers have needed to raise their confidence in a design proposal to a sufficient level in order to begin construction. For this reason, models have mostly been used by designers and constructors of highly innovative projects, when previous experience has not been available. The book covers the history of using physical models in the design and development of civil and building engineering projects including Robert Stephenson?s Britannia Bridge in the 1840s, the masonry Aswan Dam in the 1890s and the Boulder Dam in the 1930s; tidal flow in estuaries and wind and seismic loads on structures from the 1890s, the acoustics of concert halls and the design of thin concrete shell roofs from the 1920s, and the dynamic behaviour of tall buildings from the 1930s, as well as and cable-net and membrane structures in the 1960s. Individual designers featured include Eduardo Torroja, Pier Luigi Nervi, Heinz Hossdorf, Heinz Isler, Frei Otto, Sergio Musmeci and Mamoru Kawaguchi. The book concludes with overviews of the current use of physical models alongside computer models, for example in boundary layer wind tunnels, seismic engineering, hydrology, soil mechanics, and air flow in buildings. Traditionally, progress in engineering has been attributed to the creation and use of engineering science, the understanding of materials properties and the development of new construction methods. The book argues that the use of reduced-scale models has played an equally important part in the development of civil and building engineering. However, like the history of engineering design itself, this crucial contribution has not been widely reported or celebrated. The book includes 39 chapters written by 29 authors from ten different countries.

Bridging the gap between wind and structural engineering, Wind Loading of Structures demonstrates the application of wind engineering principles to ensure maximum safety in a variety of structures. This book will assist the practising engineer in understanding the principles of wind engineering, and provide guidance on the successful design of structures for wind loading by gales, hurricanes, typhoons, thunderstorm downdrafts and tornados. The principles of meteorology, statistics and probability, aerodynamics and structural dynamics are covered in the first half of the book. The second half describes, qualitatively and quantitatively, the nature of wind loads on all types of structures, including low-rise and tall buildings, large stadium roofs, towers and chimneys, bridges, transmission lines, free-standing walls and roofs, and antennae. Special features include coverage of extreme winds in tropical and sub-tropical climates, wind-tunnel testing techniques, a summary of the wind climates of over sixty countries, and detailed coverage of internal as well as external wind pressures on buildings. A comparison is made of the provisions for wind loads in six major national and international codes and standards. Examples and case studies are given in each chapter that make the book suitable for supporting university graduate courses in wind loading and response.
