Steel bridge bearings may be divided into three general types: elastomeric bearings, high-load multi-rotational bearings, and mechanical bearings. The designer must determine which bearing type is best suited to cost effectively accommodate the design requirements. This module provides practical information for efficient bearing design and detailing. The information contained in this module is drawn largely from the following two sources - National Steel Bridge Alliance's (NSBA's) “Steel Bridge Bearing Selection and Design Guide,” Highway Structures Design Guide, Volume II, Chapter 4 (Highway Structures Design Handbook Volume II, Chapter 4)) and American Association of State Highway and Transportation Officials (AASHTO)/NSBA Steel Bridge Collaboration, G9.1-2004 “Steel Bridge Bearing Design and Detailing Guidelines.”
