For concrete structural members, the bearing used is the elastomeric pad device. For steel beam and girder construction, both elastomeric bearings and steel bearing assemblies are common. There are some bridges that do not have bearing devices. The use of integral end bents (Figure 5-2) has become more common in recent years.

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.

WisDOT Bridge Manual. Chapter 27 – Bearings. July 2019 27-6 The required design input for the design of an elastomeric bearing at the service limit state is dead load, live load plus dynamic load allowance, minimum vertical force due to permanent load, and design translation. The required design input at the strength limit state is shear force.

To satisfy the 1.75 ksi limit, the minimum bearing area, A req, should satisfy:. A req > 290.5/1.75 = 166.0 in 2. The corners of the bottom flanges of the girder are usually chamfered. The bearing should be slightly narrower than the flat part of the flange unless a stiff sole plate is used to insure uniform distribution of the compressive stress and strain over the bearing area.Phone: (202) 366-4604

to those used with elastomeric bearings can be applied, or the bearing can be designed with attachments. 5.4 Miscellaneous . If a PTFE sliding element is required for an elastomeric bearing and the PTFE is the same plan dimensions as the elastomeric bearing, theoretically, a load plate between the PTFE and the elastomeric bearing is not required.
