bridge design and evaluation pdf

This book has seven chapters. Chapter 1 is an introduction to bridge engineering, including design and evaluation. Chapter 2 covers both the general and specific requirements in the AASHTO specifications for designing highway bridges. The concepts of structural reliability are also presented, which were used for the calibration of both sets of AASHTO specifications focused on here.





Chapter 3 presents further detailed specific requirements of the specifications for loads, load effects, and their combinations for highway bridge components. Chapter 4 of this book covers the
superstructure part of bridge design, Chapter 5 the bearings, and Chapter 6 the substructure. Chapter 7 shifts focus from design to evaluation (load rating) of the same bridges covered in the book.





This book is designed as a textbook for first courses of undergraduate and/or graduate studies on highway bridge design and/or evaluation according to current AASHTO specifications. For an undergraduate course of three credit hours, Chapters 1, 3, and 4 (or along with 5) are recommended to be covered. If the undergraduate course is designed for four credit hours, Chapter 5 (or 6) may be added. For a graduate course, Chapters 1 through 6 may be covered for three credit hours, and
Chapter 7 can be added for four credit hours.





Structural analysis will bea prerequisite for using this textbook, and steel and concrete designs are
preferred to be prerequisites but may be allowed as corequisites. Successful completion of the course will enable the student to perform duties of an entry-level engineer in bridge design and evaluation, according to the current AASHTO specifications.





Another alternative way of using this book is to teach only its bridge analysis and the related examples or portions of the examples. It can be part of a structural analysis course or an independent course at either undergraduate or graduate level.





The examples included in this book can be used without referring to the text. Such use can be particularly convenient for review after a level of understanding of the relevant text material is established. Therefore, they may also serve as a helpful reference for junior engineers with limited familiarity with bridge design and/or evaluation and those who are preparing for a professional engineer license exam, particularly where bridge design is a required subject.
