Book Description
Bridge design and construction technologies have experienced remarkable developments in recent decades, and numerous long-span bridges have been built or are under construction all over the world. Cable-supported bridges, including cable-stayed bridges and suspension bridges, are the main type of these long-span bridges, and are widely used in highways crossing gorges, rivers, and gulfs, due to their superior structural mechanical properties and beautiful appearance. However, cable-supported bridges suffer from harsh environmental effects and complex loading conditions, such as heavier traffic loads, strong winds, corrosion effects, and other natural disasters. Therefore, the lifetime safety evaluation of these long-span bridges considering the rigorous service environments is an essential task. Features: Presents a comprehensive explanation of system reliability evaluation for all aspects of cable-supported bridges. Includes a comprehensive presentation of the application of system reliability theory in bridge design, safety control, and operational management. Addresses fatigue reliability, dynamic reliability and seismic reliability assessment of bridges. Presents a complete investigation and case study in each chapter, allowing readers to understand the applicability for real-world scenarios. Reliability and Safety of Cable-Supported Bridges provides a comprehensive application and guidelines for system reliability techniques in cable-supported bridges. Serving as a practical educational resource for both undergraduate and graduate level students, practicing engineers, and researchers, it also intends to provide an intuitive appreciation for probability theory, statistical methods, and reliability analysis methods.

Book Description
Recent surveys of the U.S. infrastructure‘s condition have rated a staggering number of bridges structurally deficient or functionally obsolete. While not necessarily unsafe, a structurally deficient bridge must be posted for weight and have limits for speed, due to its deteriorated structural components. Bridges with old design features that canno

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.

Book Description
With the development in global economic and transportation engineering, the traffic loads on brides have been growing steadily, which become potential safety hazards for existing bridges. In particular, long-span suspension bridges support heavy traffic volumes and simultaneous truck loads on the bridge deck, and thus the safety and serviceability of the bridge deserves investigation. In this book, a multiscale reliability method is presented for the safety assessment of long-span bridges. The multiscale failure condition of stiffness girders is the first-passage criteria for the large-scale model and the fatigue damage criteria for the small-scale model. It is the objective of this book to provide a more in-depth understanding of the vehicle-bridge interaction from the random vibration perspective. This book is suitable for adoption as a text book or a reference book in an advanced structural reliability analysis course. Furthermore, this book also provides a theoretical foundation for better understanding of the safety assessment, operation management, maintenance and reinforcement for long-span bridges and motivates further research and development for more advanced reliability and serviceability assessment techniques for long-span bridges.

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

Book Description
Have you ever wondered how NASA designs, builds, and tests spacecrafts and hardware for space? How is it that wildly successful programs such as the Mars Exploration Rovers could produce a rover that lasted over ten times the expected prime mission duration? Or build a spacecraft designed to visit two orbiting destinations and last over 10 years when the fuel ran out? This book was written by NASA/JPL engineers with experience across multiple projects, including the Mars rovers, Mars helicopter, and Dawn ion propulsion spacecraft in addition to many more missions and technology demonstration programs. It provides useful and practical approaches to solving the most complex thermal-structural problems ever attempted for design spacecraft to survive the severe cold of deep space, as well as the unforgiving temperature swings on the surface of Mars. This is done without losing sight of the fundamental and classical theories of thermodynamics and structural mechanics that paved the way to more pragmatic and applied methods such finite element analysis and Monte Carlo ray tracing, for example. Features: Includes case studies from NASA’s Jet Propulsion Laboratory, which prides itself in robotic exploration of the solar system, as well as flyting the first cubeSAT to Mars. Enables spacecraft designer engineers to create a design that is structurally and thermally sound, and reliable, in the quickest time afforded. Examines innovative low-cost thermal and power systems. Explains how to design to survive rocket launch, the surfaces of Mars and Venus. Suitable for practicing professionals as well as upper-level students in the areas of aerospace, mechanical, thermal, electrical, and systems engineering, Thermal and Structural Electronic Packaging Analysis for Space and Extreme Environments provides cutting-edge information on how to design, and analyze, and test in the fast-paced and low-cost small satellite environment and learn techniques to reduce the design and test cycles without compromising reliability. It serves both as a reference and a training manual for designing satellites to withstand the structural and thermal challenges of extreme environments in outer space.
