rolled or slid, either the end diaphragms of the bridge have to be designed to support the bridge on the sliding shoes or rollers or the girders must be designed to accommodate both the sliding or rolling bearings and the permanent bearings. Throughout the process of designing and detailing the structure,
https://www.steelconstruction.info/Bridge_articulation_and_bearing_specification
Articulation is the term for the configuration of bridge supports and choice of structural bearings that provides the necessary restraints to the superstructure whilst at the same time providing freedom to some displacements and rotations in order to avoid unnecessary forces on both the superstructure and substructure due to constraint.. A range of different bearing types is available.

This is because sliding bearing cannot be purely used if the bridge experiences rotation movement. However, the span restriction for sliding bearing utilization can be disregarded when it is used in combination with other bearing types. Rocker and Pin Bearings for Bridge Structures

falsework next to the existing bridge location allows assembly of the new components to be completed while other key elements of the construction also are underway (such as piers and abutments). Extensive falsework and shoring requirements must be considered when sliding or rolling bridge superstructure systems into place.

The design of a pinned connection is a good example of the idealization of the reality. A single pinned connection is usually not sufficient to make a structure stable. Another support must be provided at some point to prevent rotation of the structure. The representation of a pinned support includes both horizontal and vertical forces.

Sep 28, 2013 · Types & Functions Of Bearings for Bridges Function Of Bearings. Bridge bearings are used to transfer forces from the superstructure to the substructure, allowing the following types of movements of the superstructure: Translation movements; are displacements in vertical and horizontal directions due to in-plane or out-of-plane forces like wind and self weight.
