can be removed without needing to lift the bridge girders significantly. Particular attention should be given to the design of supporting concrete plinths to prevent bursting or other types of failure from application of both vertical and horizontal forces. Types of bearing Table 1 shows the main types of bearing that are used in steel bridges.

Bridge Bearing Function and Desig

Design. Bearing pads are designed as per AASHTO LRFD Bridge Design Specifications-2007. The design rule is based on the assumption that rubber is a viscoelastic material, the deflection of which, under compressive loads, is influenced by its shape.

Bridge Bearings - an overview | ScienceDirect Topi

The bridge superstructure is defined as all structural elements above the bridge bearing elevation, or as the primary conduit which carries a roadway over a crossing. While the superstructure is composed of a number of elements (wearing surface, diaphragms, girders, decks, etc.), the bridge deck represents the physical extension of the roadway

Bridge Bearing - Transfer and Absorb Forc

Bridge bearing, as connection component, can provide a resting surface between bridge and bridge piers. And the purpose of bridge bearing is to transfer forces from the superstructure to the substructure or reduce the ground vibration to the superstructure.

Bridge Bearings - Elastomeric Bridge Bearing Manufactur

Elastomeric Bridge Bearings are designed to transform the movement and rotation of bridge structure into elasticity and minimizes the secondary stress generated in the bridge because of the layered rubber sheets reinforced by metal plates. These bearings are designed to accommodate vertical, longitudinal, horizontal and transverse loads movements and rotation of the superstructure caused by
