Steel Bridge Bearing Design and Detailing Guidelines

Steel Bridge Bearing Design and Detailing Guidelines 


Preference :

This document is a standard developed by the AASHTO/ NSBA Steel Bridge Collaboration. The primary goal of the Collaboration is to achieve steel bridges of the highest quality and value through standardization of the design, fabrication, and erection processes. Each standard represents the consensus of a diverse group of professionals. As consensus documents, the Collaboration standards represent the best available current approach to the processes they cover. It is intended that Owners adopt and implement Collaboration standards in their entirety to facilitate the achievement of standardization, but it is understood that local statutes or preferences may prevent full adoption of the document. In such cases, Owners should adopt these documents with the exceptions they feel are necessary. The following guidelines and details are for typical steel bridges. The Collaboration recognizes that most states currently have standards for bearings, however, it is the intent that states will adopt or modify their standards for steel bridge bearings to conform to this guideline. In many cases, options for economic bearings are offered to facilitate the acceptance and use of this document.
