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 - NSBA’s “Steel Bridge Bearing and Selection and Design
Guide,” Highway Structures Design Guide, Volume II, Chapter 4 (HSDH Volume II, Chapter 4)) and AASHTO/NSBA Steel Bridge Collaboration, G9.1-2004 “Steel Bridge Bearing Design and Detailing Guidelines.”
