✦ Synopsis

Since the first edition of the American Association of State Highway and Transportation Officials (AASHTO) LRFD Bridge Design Specifications in 1994, U.S. highway bridge design has been moving towards load and resistance factor design (LRFD). Prior to that, for more than a half of century, highway bridge design practice has been using the load factor design (LFD) and service load design (SLD), according to the AASHTO Standard Specification for Highway Bridges. Furthermore, in 2003, the first edition of AASHTO Manual for Condition Evaluation and Load and Resistance Factor Rating (LRFR) of Highway Bridges was issued for bridge evaluation and load rating. In 2007, AASHTO mandated the LRFD specifications in the United States after more than a decade of preparation, including trial use and software development. With the Federal Highway Administration’s (FHWA’s) requirement and also for consistency, a number of states have started the practice of LRFR for bridges designed according to LRFD. This introductory book covers the LRFD and LRFR methods for highway bridges as a textbook for a first undergraduate and/or graduate course on highway bridge design and/or evaluation.
