Planning And Design Of Bridges

Timely, authoritative, extremely practical--an exhaustive guide tothe nontheoretical aspects of bridge planning and design. This bookaddresses virtually all practical problems associated with theplanning and design of steel and concrete bridge superstructuresand substructures. Drawing on its author's nearly half-century as abridge designer and engineer, it offers in-depth coverage of suchcrucial considerations as selecting the optimum location andlayout, traffic flow, aesthetics, design, analysis, construction,current codes and government regulations, maintenance andrehabilitation, and much more. * Offers in-depth coverage of all the steps involved in performingproper planning and design with comparative analyses of alternativesolutions * Includes numerous examples and case studies of existing bridgesand important projects underway around the world * Features a time-line history of bridge building from pre-Romantimes to the present * Summarizes key technical data essential to bridgeengineering * Supplemented with 200 line drawings and photos vividlyillustrating all concepts presented * Comprehensive coverage of CAD planning, design, and analysistechniques and technologies

This new edition encompasses current design methods used for steel railway bridges in both SI and Imperial (US Customary) units. It discusses the planning of railway bridges and the appropriate types of bridges based on planning considerations.

The main contents of this book include: overview, planing study of bridge, technical standards and general layout, overall design of beam bridge, arch bridge, cable-stayed bridge, suspension bridge, composite structure bridge, environmental protection and landscaping design of bridge, bridge maintenance, monitoring and repair design , life cycle design and engineering risk analysis, etc.. It covers various aspects of bridge planning, design, construction, maintenance, etc., and introduces key technologies for the development of current bridges, which is very informative. It is highly instructive and practical, suitable for bridge construction personnel engaged in bridge planning, design, scientific research. It can also be used as a reference for teachers and students of related majors in universities and colleges.

The role of the designer and architect in the planning and design of bridges is undergoing radical change, with architects now being appointed before the engineer on a growing number of projects. The relationship between the two roles is therefore on a different level than either will have previously experienced. This book details the process of design whereby the inspiration for a bridge is developed into the final reality of the built solution. It looks at the functions of a bridge, defining purpose of place and context, the spirit of creativity and the reasoned progression of an idea. It also explores the exploitation of materials technology and construction innovation, and the tension between lightness and mass and between sculpture and scale. The architecture of bridge design takes the form of a number of submissions from leading architects and engineers, each setting out their views on bridge design - present and future. As well as providing vital source material for those tendering for bridge projects in which they will be closely involved in the design process, it also provides a state-of-the-art statement on modern bridge design form the viewpoint of client, architect and engineer.

Perhaps the first book on this topic in more than 50 years, Design of Modern Steel Railway Bridges focuses not only on new steel superstructures but also outlines principles and methods that are useful for the maintenance and rehabilitation of existing steel railway bridges. It complements the recommended practices of the American Railway Engineering and Maintenance-of-way Association (AREMA), in particular Chapter 15-Steel Structures in AREMA’s Manual for Railway Engineering (MRE). The book has been carefully designed to remain valid through many editions of the MRE. After covering the basics, the author examines the methods for analysis and design of modern steel railway bridges. He details the history of steel railway bridges in the development of transportation systems, discusses modern materials, and presents an extensive treatment of railway bridge loads and moving load analysis. He then outlines the design of steel structural members and connections in accordance with AREMA recommended practice, demonstrating the concepts with worked examples. Topics include: A history of iron and steel railway bridges Engineering properties of structural steel typically used in modern steel railway bridge design and fabrication Planning and preliminary design Loads and forces on railway superstructures Criteria for the maximum effects from moving loads and their use in developing design live loads Design of axial and flexural members Combinations of forces on steel railway superstructures Copiously illustrated with more than 300 figures and charts, the book presents a clear picture of the importance of railway bridges in the national transportation system. A practical reference and learning tool, it provides a fundamental understanding of AREMA recommended practice that enables more effective design.

Whether you are a student considering a career in civil engineering and transportation planning, a public official interested in the future of infrastructure, or a person who simply cares about bridges, this book offers an accessible and illustrated introduction to the most beloved feature of our built environment. Learn about engineering basics: the forces that bridges must resist to stay aloft and the principles by which engineers decide which types of bridges make sense at which sites. Find out how engineers protect bridges from their greatest threats—the earthquakes, floods, and other hazards that can cause catastrophic damage. Moving from engineering to planning, learn how we decide whether a bridge is worth building in the first place, learn about controversial features of cost-benefit analysis, and about the transportation models by which planners forecast bridge effects on traffic patterns. Investigate a sometimes intractable problem: why a project often creeps along for a decade or more to get from initial studies to the day the ribbon is cut, undergoing vast cost escalations. Also explore the environmental impact of bridges, and the meaning of a "sustainable bridge," and whether bridges could once again be built, like ancient Roman ones, to last a thousand years.
