What is bearing pads in bridges?
Elastomeric bearing pads compress on vertical load and accommodate horizontal rotation and provide lateral shear movement. Elastomeric bearing pads are the most economical solution used in construction of large span bridges and buildings.
What is elastomeric bearing pad made of?
neoprene
Elastomeric Bearing Pad Role of the Elastomeric Bearing Pad This is typically made of a strong and pliable material such as neoprene—a type of heavy-duty industrial rubber. These pads are placed in between superstructures such as the bridge beam and substructures such as the vertical supports called piers.
What is high damping rubber?
A HDRB is a laminated rubber bearing that uses specialized high damping rubber (HDR) with the capacity to absorb energy as it transforms itself due to external energy sources such as earthquakes, as the same rubber bearing as the lead rubber bearing and the seismic isolation equipment with damping function [3].
What is spherical bridge bearing?
Spherical Bridge Bearing. Spherical Bridge Bearing. Brief Description : The Spherical Bearing is a structural bearing which consists of a set of concave & convex mating steel backing plate with a low friction sliding interface in between thereby permitting rotation by incurve sliding.
How are elastomeric bearing pads used in bridge construction?
Internal structure consists of a sandwich of mild steel shims and rubber moulded as one unit. Elastomeric bearing pads compress on vertical load and accommodate horizontal rotation and provide lateral shear movement. Elastomeric bearing pads are the most economical solution used in construction of large span bridges and building
What are the different types of bearing pads?
There are several different similar types of bridge bearings that include neoprene bearing pads, neoprene bridge bearings, laminated elastomeric bearings and seismic isolators which are all generally referred to as bridge bearing pads in the construction industry.
What kind of bearing pads do Denver rubber use?
Designed to handle vertical loading and accommodate thermal expansion, our elastomeric bearing pads are ideal for applications subjected to vibration, shock, shear and rotation forces. Denver Rubber Company elastomeric bearing pads meet the most stringent requirements.
