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.

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,

Testing of Elastomeric Bearings for Bridges

2006
The aim of these testings was to determine mechanical characteristics of elastomeric bearings for new Jankomir bridge over Sava river in Zagreb with emphasis on the characteristics in horizontal direction under vertical load. Tested bearings were roun shaped with diameter of 450 mm and total height of 111 mm type V2ES 2400/190 (thickness of elastomeric

Radial elastomeric bearings: testing and indications of failure

Tribology International, 1982
Abstract Tests made on 12 radial elastomeric bearings to determine indications of failure and life are described. Dwell times of one hour in the test sequence did notsignificantly affect bearing life. The best measurements for the assessment of bearing condition were crater depth and change in stiffness in the direction of compression ...

Tensile load‐carrying behaviour of elastomeric bearings

Steel Construction, 2015
AbstractElastomeric bearings for seismic isolation applications can be subjected to tensile loads depending on the geometrical configuration, high vertical seismic motion or excessive horizontal deformation due to the elongated‐period horizontal motion.

VULNERABILITY OF ELASTOMERIC BEARING ISOLATED BUILDINGS AND THEIR EQUIPMENT

Journal of Earthquake Engineering, 2005
In this paper, we compare the vulnerability of isolated and conventional structures as well as equipment when uncertainty on the excitation and on some of the structural properties is considered. This comparison is performed, mainly, with a series of Monte Carlo simulations.

High-Load Elastomeric Bridge Bearings

Transportation Research Record: Journal of the Transportation Research Board, 1996
The use of elastomeric bearings as high-load bridge bearings for steel and concrete bridges is discussed. The Washington State Department of Transportation's (WSDOT's) experience with high-load multirotational bearings and search for simpler, more durable, and more economical high-load bridge bearings are described.

Analysis of compression of hollow circular elastomeric bearings

Engineering Structures, 1992
Abstract Seismic isolation is a design technique in which structures are mounted on horizontally flexible elements which shift the natural frequency of the structure to low values and enhance damping. Elastomeric bearings, made of interleaved rubber layers and steel plates, respresent horizontally flexible elements commonly used in seismic isolation.
