Bridge bearing - Wikipedia
A bridge bearing is a component of a bridge which typically provides a resting surface between bridge piers and the bridge deck. The purpose of a bearing is to allow controlled movement and thereby reduce the stresses involved.
Bridge Bearings -Types of Bearings for Bridge Structures and …
Bridge bearings are structural equipment or devices installed between bridge substructure and superstructure to transfer the applied load including earthquake loads; wind loads; traffic loads; and superstructure self-weight.
Bridge Bearings: Types, Their Function and Applications
2021年9月22日 · Bridge bearings are mechanical components that are provided to the bridge between the substructure (abutment) and superstructure. They help in transmitting the live load from the superstructure, dead load, wind load, earthquake load impact load, etc.
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. The details are for steel reinforced elastomeric pads; however, much of the content is directly applicable to fiberglass reinforced, plain, and cotton duck pads as well.
Four major types of bridge bearings are presented: Section 1 primarily addresses steel-reinforced elastomeric pads; however, much of the content is directly applicable to fiberglass-reinforced, plain, and cotton duck pads as well. Section 2 addresses pot, disc, and spherical bearings.
Bridge Bearing – Purpose, Types, Design & Selection
Bridge bearings are structural components that facilitate the transfer of forces between the bridge superstructure and substructure. They are designed to support vertical loads such as the weight of the structure and vehicle loads, as well as lateral loads such as wind and earthquake forces.

Bridge Bearings
Indian Railways are custodians of one of the largest bridge stock under one management with more than 1,15,000 bridges on the rail network. It is important to construct new bridges with highest standard of quality and to maintain them for smooth movement of railway traffic. Bridge bearings play a very important role in keeping the bridge ...
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 …
Although many different types of bridge bearings have been used by the NYSDOT, elastomeric and multi-rotational bearings are the only general types of bridge bearings currently being used on new bridges of short to moderate length. Major-span bridges require special bearings to handle their extreme loads, movements, and rotations.
