Available in PDF, EPUB and Kindle. Book excerpt: This work presents a study of the simulation of cable-stayed bridges built on temporary supports focused on their response during construction and in service. To simulate the behavior during construction, a set of four different algorithms has been developed to deal with initial design (Backward Algorithm), updating the tensioning process when deviations on site are measured (Forward Algorithm), optimization processes (Direct Algorithm) and time-dependent phenomena effects (Forward-Direct Algorithm). These algorithms were validated by comparing their results with those obtained by two commercial codes. On the other hand, new criteria have been proposed to include the effects of the staggered erection of the superstructure and the time-dependent phenomena effects into the definition of the Objective Service State. To illustrate the application of these methods, a set of academic and actual structures is analyzed. For a more accurate simulation of the actual response of structures on site, a new Structural System Identification (SSI) method (Observability method) is developed. This method is based on the information provided by the monitoring of a static non-destructive test. After validating the results of this method with three alternative methods proposed in the literature, it is applied to complex structures (such as singular buildings and cable-stayed bridges). A parametric analysis is presented to illustrate the role that the uncertainty of each parameter of a real cable-stayed bridge plays in its behavior during construction and in service. Furthermore, modifications of this method to deal with damages, actual boundary conditions, temperature effects, and dynamic excitation tests are presented. The developed SSI method has also lead to the development of a very powerful mathematical tool to deal with polyrational systems of equations. This tool presents a number of applications in many fields of science and engineering (such as transportation, hydraulics or energy power distribution, among many others). To define the minimum measurement set of measurements required for an adequate system identification, a new and innovative graphical tool (observability tree) is developed. To ease the representation of these trees, a set of guidelines is proposed for beam and cable-stayed bridges. To minimize the degrees of freedom to be monitored on site for system identification with actual loads, a new application of the Maxwell's theorem has been proposed. To this end, the utilization of information from alternative load cases, boundary conditions and construction stages is also presented. The results of the proposed methods have led to significant conclusions regarding the response of the cable-stayed bridges built on temporary supports both during construction and in service as well as the importance of their construction control by SSI techniques. From these conclusions, a set of guidelines has been proposed to address the erection of the superstructure, to estimate the appropriate time to define the stay cable forces in service in concrete cable-stay bridges considering time-dependent phenomena effects, to define a measurement set for an adequate SSI and to minimize the points to be monitored.

Book Synopsis Cable-Stayed Bridges by : Holger Svensson
Download or read book Cable-Stayed Bridges written by Holger Svensson and published by John Wiley & Sons. This book was released on 2013-08-06 with total page 458 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Book Synopsis Cable Supported Bridges by : Niels J. Gimsing
Download or read book Cable Supported Bridges written by Niels J. Gimsing and published by John Wiley & Sons. This book was released on 2011-12-30 with total page 760 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Available in PDF, EPUB and Kindle. Book excerpt: 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 Synopsis Basic Principles of Cable Supported Bridges by : DR. B C ROY
Download or read book Basic Principles of Cable Supported Bridges written by DR. B C ROY and published by Notion Press. This book was released on 2024-05-15 with total page 310 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.
