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.
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.
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.
Elastomeric bearings allow transfer of vertical loads, horizontal movement, and structural rotation. They are valued for their durability, reliability, low maintenance requirements, and low cost. Because elastomeric bearing pads are crucial for safe and cost-effective concrete bridge design, we posed questions about them to the experts.
11 Αυγ 2021 · Elastomeric bearing pad in a concrete bridge. The design of elastomeric bearings deals with the equilibrium between having sufficient stiffness that can withstand the imposed vertical loads and enough flexibility to allow for the expected deformations.
An elastomeric bridge bearing, also known as a pot bearing or elastomeric bearing, is a commonly used modern bridge bearing. The term encompasses several different types of bearings including bearing pads, bridge bearings, laminated elastomeric bearings, and seismic isolators ...
