Laminated Elastomeric Bearings: An Overview

SAE Technical Paper Series, 1989
<div class="htmlview paragraph">The use of high performance Laminated Elastomeric Bearings is offered as an alternative to conventional roller element or metallic contact bushings for continuous load support and motion control. The discussion includes the design considerations necessary for proper application, as well as the Engineering ...

Behavior of Elastomeric Bridge Bearings: Computational Results

Journal of Bridge Engineering, 1998
A p-version, two-dimensional (2D) finite-element model incorporating both material and geometric nonlinearities and a consistent frictional contact algorithm is utilized to analyze elastomeric bridge bearings. Stresses and strains are examined and factors affecting them are discussed.

Design Process for Multilayered Elastomeric Bearings

1993
The preliminary design of a bearing in an isolation system begins with the determination of the vertical load to be carried by the bearing. In most buildings the design load at each column (based on dead load plus live load due to fixed partitions, equipment, furniture, etc.) can vary quite widely.

Finite Deformation Stiffness of Sliding Elastomeric Bearings

Advanced Materials Research, 2011
Anchor bolts are set in some elastomeric bearings of large-span column-supported spatial steel roofs. Besides helping the bearing in-site assembly, the bolts play the roles of sliding position limitation and vertical anchorage. To analyze the effect of bearings on nonlinear structural behavior, the bearing stiffness change is studied just before and ...

Buckling Behavior of Elastomeric Bearings

1993
A multilayer elastomeric bearing can be susceptible to a buckling type of instability similar to that of an ordinary column, but dominated by the low-shear stiffness of a bearing. The previous analysis of the overall deformation of a single pad can be used in a buckling analysis that treats the bearing as a continuous composite system. In this analysis,

Effect of Friction on Unbonded Elastomeric Bearings

Journal of Engineering Mechanics, 2009
This paper describes a theoretical analysis of a type of thermal expansion bridge bearing which could be used as a lightweight low-cost elastomeric seismic isolator for application to housing, schools, and other public buildings in earthquake-prone areas of the developing world.

Tension Buckling in Multilayer Elastomeric Bearings

Journal of Engineering Mechanics, 2003
The compression buckling of mutilayer elastomeric bearings which are widely used as vibration mounts, bridge bearings, and seismic isolators for buildings is well understood and is governed by theoretical analysis and confirmed by extensive experimental work. What is not well known is that the theoretical analysis that predicts the compression buckling

Long-Term Performance of Elastomeric Bridge Bearings

Transportation Research Record: Journal of the Transportation Research Board, 1999
The effects of long-term service on bridge bearings composed of steel plates laminated between elastomeric layers, as placed on twin structures carrying the Route 400 Aurora Expressway over Route 16 and Conrail tracks in New York’s Erie County, are summarized.

Characteristics of various elastomeric bearings in tension

Steel Construction, 2009
AbstractIt has been a long time since seismic isolation was invented with the aim of protecting lives and structures against earthquakes. Seismic isolation is achieved by installing special bearings, so‐called isolators, between the foundations of buildings or the piers of bridges and the superstructure.
