The American Association of State Highway and Transportation Officials (AASHTO) and the National Steel Bridge Alliance (NSBA) have a joint effort under way to enhance the quality and value of steel bridge design and construction in the United States. Under this effort, known as the AASHTO/NSBA Collaboration, representatives of the state departments of transportation, the Federal Highway Administration, steel and construction industries, design professionals, and academia have been working together. Issues such as how the Collaboration operates and how, as a comprehensive resource for steel bridges, it works to enhance the state of the art for steel bridges through implementation of technology and exchange of resources among its participants are discussed. Furthermore, standard practices, specifications, guidelines, and details that were developed as a consensus by the Collaboration for steel bridge design, fabrication, and erection are presented. |
