STEEL BRIDGE BEARING SELECTION GUIDE by Charles W. Roeder, Ph.D., P.E., and John F. Stanton, Ph.D., P.E. University of Washington SELECTION OF BEARINGS FOR STEEL BRIDGES This Selection Guide facilitates the process of selecting cost-effective and appropriate bearing systems for steel girder bridges.
The purpose of this guide is to present steel bridge bearing details that are cost effective, functional, and durable. Three major types of bridge bearings are presented. 1. Elastomeric bearings The details are for steel reinforced elastomeric pads; however, much of the content is directly
1 Ιουν 2023 · An elastomeric bearing pad plays a crucial role in bridge safety, dependability, and longevity. Read how simulation helps.
Plain elastomeric bearing pads (PEP) rely upon friction at the contact surfaces to resist bulging. Local slip resulting from friction loss leads to increased strain, thus limiting the load carrying capacity of the bearing.
Redwood Plastics is the exclusive manufacturer of Redco™ Dynamex™ Engineered Elastomeric Bearings for Bridges and Structures. Redco™ Dynamex™ products conform to CAN/CSA, AASHTO, AREMA and OPSS standards and are available in a wide range of configurations.
specifying and installing bearing pads, the PCI Committee on Bridges has added this topic to their selection of online courses. Elastomeric bearing pads have been used for decades for transferring loads on all types of concrete bridges. The terms “elastomeric bridge bearing,” “pot bearing,” and “elastomeric bearing” are often used
Since 2005 the European standard EN 1337-3 has applied to elastomeric bearings for architectural and civil-engineering applications. Besides the functional requirements, the standard describes the design rules, the material properties, the production tolerances and the acceptance tests.
