A How-To Guide for Bridge Engineers and Designers Highway Bridge Superstructure Engineering: LRFD Approaches to Design and Analysis provides a detailed discussion of traditional structural design perspectives, and serves as a state-of-the-art resource on the latest design and analysis of highway bridge superstructures. This book is applicable to highway bridges of all construction and material types, and is based on the load and resistance factor design (LRFD) philosophy. It discusses the theory of probability (with an explanation leading to the calibration process and reliability), and includes fully solved design examples of steel, reinforced and prestressed concrete bridge superstructures. It also contains step-by-step calculations for determining the distribution factors for several different types of bridge superstructures (which form the basis of load and resistance design specifications) and can be found in the AASHTO LRFD Bridge Design Specifications. Fully Realize the Basis and Significance of LRFD Specifications Divided into six chapters, this instructive text: Introduces bridge engineering as a discipline of structural design Describes numerous types of highway bridge superstructures systems Presents a detailed discussion of various types of loads that act on bridge superstructures and substructures Discusses the methods of analyses of highway bridge superstructures Includes a detailed discussion of reinforced and prestressed concrete bridges, and slab-steel girder bridges Highway Bridge Superstructure Engineering: LRFD Approaches to Design and Analysis can be used for teaching highway bridge design courses to undergraduate- and graduate-level classes, and as an excellent resource for practicing engineers.

Developed to comply with the fifth edition of the AASHTO LFRD Bridge Design Specifications [2010]––Simplified LRFD Bridge Design is "How To" use the Specifications book. Most engineering books utilize traditional deductive practices, beginning with in-depth theories and progressing to the application of theories. The inductive method in the book uses alternative approaches, literally teaching backwards. The book introduces topics by presenting specific design examples. Theories can be understood by students because they appear in the text only after specific design examples are presented, establishing the need to know theories. The emphasis of the book is on step-by-step design procedures of highway bridges by the LRFD method, and "How to Use" the AASHTO Specifications to solve design problems. Some of the design examples and practice problems covered include: Load combinations and load factors Strength limit states for superstructure design Design Live Load HL- 93 Un-factored and Factored Design Loads Fatigue Limit State and fatigue life; Service Limit State Number of design lanes Multiple presence factor of live load Dynamic load allowance Distribution of Live Loads per Lane Wind Loads, Earthquake Loads Plastic moment capacity of composite steel-concrete beam LRFR Load Rating Simplified LRFD Bridge Design is a study guide for engineers preparing for the PE examination as well as a classroom text for civil engineering students and a reference for practicing engineers. Eight design examples and three practice problems describe and introduce the use of articles, tables, and figures from the AASHTO LFRD Bridge Design Specifications. Whenever articles, tables, and figures in examples appear throughout the text, AASHTO LRFD specification numbers are also cited, so that users can cross-reference the material.

A succinct, real-world approach to complete bridge systemdesign and evaluation Load and Resistance Factor Design (LRFD) and Load and ResistanceFactor Rating (LRFR) are design and evaluation methods that havereplaced or offered alternatives to other traditional methods asthe new standards for designing and load-rating U.S. highwaybridges. Bridge Design and Evaluation covers complete bridgesystems (substructure and superstructure) in one succinct,manageable package. It presents real-world bridge examplesdemonstrating both their design and evaluation using LRFD and LRFR.Designed for a 3- to 4-credit undergraduate or graduate-levelcourse, it presents the fundamentals of the topic without expandingneedlessly into advanced or specialized topics. Important features include: Exclusive focus on LRFD and LRFR Hundreds of photographs and figures of real bridges to connectthe theoretical with the practical Design and evaluation examples from real bridges includingactual bridge plans and drawings and design methodologies Numerous exercise problems Specific design for a 3- to 4-credit course at theundergraduate or graduate level The only bridge engineering textbook to cover the importanttopics of bridge evaluation and rating Bridge Design and Evaluation is the most up-to-date andinclusive introduction available for students in civil engineeringspecializing in structural and transportation engineering.

Movement of bridge substructures can adversely affect the strength and serviceability of bridge superstructures. Research concluded in 1985 utilized field and analytical studies to create tolerable bridge movement limits. Because the limits were determined based on the design and loading provisions of the American Association of State Highway and Transportation Officials (AASHTO) Standard Specifications for Highway Bridges, there was a need for the previous research to be reproduced and updated based on the provisions of the AASHTO Load and Resistance Factor Design (LRFD) Bridge Design Specifications. Simple two-dimensional analytical models and models of actual in-service highway bridges were analyzed in order to study the effects of differential vertical movement. The results obtained from the analyses suggested that, in general, the reserve moment capacities of bridge girders are sufficient to resist the additional stresses caused by differential settlement of bridge substructures. Despite the ability of most bridges to tolerate small magnitudes of differential vertical substructure movement, expected movements should be accounted for during the design process to ensure that safety and reliability are maintained. A method of calculating the effects of anticipated differential settlements was determined. It is recommended that force effects associated with anticipated differential vertical movements of substructures be included in the design of bridge girders.
