SVI – Structural Bearing Design – 10a
Design of Elastomeric Structural Bearings

Introduction
This document has been created to provide an insight into
the design and selection of our materials in order to assist
in the understanding of technical datasheets and in the
selection of an appropriate material for a particular
application. Farrat are manufacturers of acoustic and
vibration isolation bearings rather than traditional bridge
bearings (for road bridges etc) but we have summarised
the principles behind bridge bearings to explain the
distinctions.
Farrat elastomeric (rubber) isolation materials are high
quality, easy to use and economical. Produced in the UK
by Farrat using high quality compounds they provide
excellent tuned frequency vibration, acoustic and shock
isolation as well as predictable, low long term creep
performance and have been used globally in industrial
and structural applications.

Structural Bearing Design

The most common applications for elastomeric structural
bearings are either as bridge bearings or acoustic and
vibration isolation bearings. Although similar in appearance
and design the two applications require the bearings to
perform different functions and different design
considerations apply to each case.
