Design of Highway Bridges An LRFD Approach
PDF Free Download | Design of Highway Bridges An LRFD Approach Second Edition by Richard M. Barker and Jay A. Puckett.
It is also written for practicing civil engineers who have an interest in the design of highway bridges.
The objective is to provide the reader a meaningful introduction to the design of medium- and short-span girder bridges.
This objective is achieved by providing fundamental theory and behavior, background on the development of the specifications, procedures for design, and design examples.
This book is based on the American Association of State Highway and Transportation Officials (AASHTO) LRFD Bridge Design Specifications, Third Edition, and Customary U.S. units are used throughout.
The general approach is to present theory and behavior upon which a provision of the specifications is based, followed by appropriate procedures, either presented explicitly or in examples.
The examples focus on the procedures involved for a particular structural material and give reference to the appropriate article in the specifications.
It is, therefore, suggested that the reader have available a copy of the most recent edition of the AASHTO LRFD Bridge Design Specifications.
The scope is limited to a thorough treatment of medium- and short-span girder bridges with a maximum span length of about 250 ft.
These bridge structures comprise approximately 80% of the U.S. bridge inventory and are the most common bridges designed by practitioners.
Their design illustrates the basic principles used for the design of longer spans. Structure types included in this book are built of concrete and steel.
Concrete cast-inplace slab, T-beam, and box-girder bridges and precast–prestressed systems are considered. Rolled steel beam and plate girder systems that are composite and noncomposite are included.
Civil engineers are identified as primary users of this book because their formal education includes topics important to a highway bridge designer.
These topics include studies in transportation systems, hydrodynamics of streams and channels, geotechnical engineering, construction management, environmental engineering, structural analysis and design,
life-cycle costing, material testing, quality control, professional and legal problems, and the people issues associated with public construction projects.
This reference to civil engineers is not meant to exclude others from utilizing this book. However, the reader is expected to have one undergraduate course in structural design for each structural material considered.
For example, if only the design of steel bridges is of interest, then the reader should have at least one course in structural analysis and one course in structural steel design.
Chapter 1 introduces the topic of bridge engineering with a brief history of bridge building and the development of bridge specifications in the United States.
Added to the second edition is an expanded treatment of bridge failure case histories that brought about changes in the bridge design specifications.
Chapter 2 emphasizes the need to consider aesthetics from the beginning of the design process and gives examples of successful bridge projects.
Added to the second edition are a discussion of integral abutment bridges and a section on the use of computer modeling in planning and design.
Chapter 3 presents the basics on load and resistance factor design (LRFD) and indicates how these factors are chosen to obtain a desirable margin of safety.
Included at the end of all the chapters in the second edition are problems that can be used as student exercises or homework assignments.
Chapter 4 describes the nature, magnitude, and placement of the various loads that act on a bridge structure.
Chapter 5 presents influence function techniques for determining maximum and minimum force effects due to moving vehicle loads.
Chapter 6 considers the entire bridge structure as a system and how it should be analyzed to obtain a realistic distribution of forces.
Chapters 7 and 8 are the design chapters for concrete and steel bridges. Both chapters have been significantly revised to accommodate the trend toward U.S. customary units within the United States and away from SI.
New to the second edition of the concrete bridge design chapter are discussions of high-performance concrete and control of flexural cracking,
changes to the calculation of creep and shrinkage and its influence on prestress losses, and prediction of stress in unbonded tendons at ultimate.
Chapter 8 includes a major reorganization and rewrite of content based upon the new specifications whereby Articles 6.10 and 6.11 were completely rewritten by AASHTO.
This specification rewrite is a significant simplification in the specifications from the previous editions/interims; however, the use of these articles is not simple, and hopefully Chapter 8 provides helpful guidance.
The organization of the design chapters is similar. A description of material properties is given first, followed by general design considerations.

Preface to Highway Bridges PDF Book
This book has the same intent as the first edition and is written for seniorlevel undergraduate or first-year graduate students in civil engineering.It is also written for practicing civil engineers who have an interest in the design of highway bridges.
