Open publisher page 0 citations

Abstract

In 1993, after a 5-year concentrated effort, the American Association of State Highway and Transportation Officials (AASHTO) adopted the AASHTO LRFD Bridge Design Specifications for load and resistance factor design (LRFD). In 1997 the AASHTO Subcommittee on Bridges and Structures decided that the LRFD Specifications will become the primary specifications for bridge design in 1999. This article briefly discusses the development of the new specifications, ongoing specification maintenance, training engineers to use the new specifications, software development, and development of other AASHTO LRFD-based specifications.
