Product Description
Title goes here.
This super high damping rubber bearing HDR-S is made of a rubber compound with high natural rubber (NR) content and has been specially designed to combine friction damping and viscous damping. As a result, it offers excellent functionality as a seismic isolation bearing, providing restorative attributes of rubber springs along with superior damping performance and high-level durability.
Features of Super High Damping Rubber Bearings
1.Environmentally friendly
The special rubber used has a strong damping attribute. This gives the eco-friendly, advanced HDR-S rubber bearing higher functionality, similar to that of conventional rubber bearings.
2.Cost reduction
The HDR-S has 20% higher damping performance than conventional HDRs. It is therefore more effective, while its design makes it compact and slim at bottom. It helps reduce overall costs of bridges.
3.Superior deformation performance
The HDR-S outperforms natural rubber bearings in terms of deformation resistance. It functions steadily during repeated deformation forces of a major earthquake. Various tests of dependability and a shear deformation performance test have proved it to be reliable in long-term durability and performance safety.

Product Description
Base Isolation System
Base Isolation System is one of the most popular means of protecting a structure against earthquake forces.
A base isolation system is a method of seismic protection where the structure (superstructure) is separated from the base (foundation or substructure). By separating the structure from its base the amount of energy that is transferred to the superstructure during an earthquake is reduced significantly.
These base isolation systems often tend to include one or more type of bearing to support the weight of the structure. Some examples of these components are; elastomeric pads, sliding plates or inverted pendulums. All of these components can provide some level of energy dissipation, but typically only in the form of hysteretic damping. Hysteretic damping has certain limitations in terms of energy absorption and can excite higher modes in some cases.

LRB- Lead Rubber Bearing
Lead Core Rubber Bearings (LRB) consists of a laminated rubber and steel bearing with steel flange plates for mounting to the
structure. Ninety percent of our isolators have an energy dissipating lead core. The rubber in the isolator acts as a spring. It
is very soft laterally but very stiff vertically. The high vertical stiffness is achieved by having thin layers of rubber reinforced by steel shims. These two characteristics allow the isolator to move laterally with relatively low stiffness yet carry significant axial load due to their high vertical stiffness.

These two characteristics allow the isolator to move laterally with relatively low stiffness yet carry significant axial load due to their high vertical stiffness.
The lead core provides damping by deforming plastically when the isolator moves laterally in an earthquake. The shims for isolators are cut to exacting tolerances by laser. The steel mounting plates are machined by computer-controlled milling machines that give high production throughput and accuracy. Molding each bearing takes 8 to 48 hours depending on the size of the bearing. The curing phase is continuously monitored to ensure that the rubber is uniformly cured throughout the bearing.
HDRB-High Damping Rubber Bearing
The HDRB isolators contain layers of rubber and reinforcing steel plates.These component let the HDRB isolate the bridge/building/ structure due to the horizontal stiffness and they can dissipate energy up to 15% damping due to high damping rubber compound. A HDRB isolators fulfil the following requirements: Transmit the vertical loads due to permanent and accidental effects ; Capacity to support horizontal loads due to service load conditions with very low displacements;
Capacity of isolate the structure by shifting the fundamental vibration period to an optimal and safe level; Capacity to dissipate energy to reduce the horizontal displacement of the isolated structure with respect to the ground. HDRB’s do not damage the structure that remains due to the elastic response for high intensity earthquakes with no interruption of the structural function. This is a primary goal for strategic structures (hospitals, control rooms, etc…)
NRB-Natural Rubber Bearing
Rubber bearing that uses natural rubber. It has low damping performance (about 2~3% at equivalent damping factor), excellent linearity, and stable restoring force characteristic.
Separate damper is required, but with combination of damper types, attenuation, etc., it is possible to design with greater
flexibility.
Rubber material has four different kinds of elastic modulus(referred as G0.30, G0.35, G0.40, G0.45), able to support wide range of
column loads.

ESB-Elastic Sliding Bearing
It is consist of 2 pieces: 1) a natural rubber bearing bonded with PTFE(Teflon) material and 2) a stainless steel slide plate. Small displacements are absorbed by the rubber itself, while large displacements cause the rubber bearing to slide on the plate.
Since the restoring function will be lost when the sliding occur r ed, normally it is used in combination with NRB, LRB or HDR.
There are three different type offriction coefficient, which type to be used is based on necessity of damping.
