High-bearing Capacity Seismic Isolation Bearings

Ultra-high Damping and Seismic Isolation Rubber Bearing for Bridges

High-performance Seismic Isolation Bearings for Buildings

The company's technical team provides preliminary consultation, seismic  (vibration) isolation analysis, review support, and customized solutions for seismic (vibration) isolation projects in buildings, bridges, and equipment.

The high load-bearing capacity seismic isolation bearings feature outstanding technical characteristics and superior performance. They are suitable for seismic isolation and mitigation in new bridge designs and can also be used in reinforcement and renovation projects to enhance the seismic safety of existing bridges. It is suitable for temperatures ranging from -20°C to +60°C, with a service life exceeding 50 years. The technical characteristics are as follows:

High vertical bearing capacity

· Designed compressive stress reaches 25MPa, and ultimate compressive stress is 175MPa.

Effective damping and energy dissipation

· The equivalent damping ratio exceeds 10%.

High durability

· Excellent resistance to ozone, aging, and corrosion.

Easy Installation

· Compact bearing size facilitates construction, installation, maintenance, and replacement.

Green and Environmentally Friendly Materials

· Green and Environmentally Friendly Materials

The ultra-high damping isolation rubber bearing is made by vulcanizing ultra-high damping rubber materials with structural components like steel plates, providing excellent damping performance. Ultra-high damping rubber bearings maintain the excellent mechanical properties of laminated rubber bearings, while providing higher damping values, superior seismic isolation, energy dissipation, and impact damage resistance. The technical characteristics are as follows:

Effective seismic isolation

· Strong horizontal displacement capability that effectively absorbs seismic energy.

Stable and reliable performance

· Moderate horizontal stiffness meets the requirements for both seismic and conventional displacements.

High damping ratio

· The material exhibits good damping performance, with a damping ratio of no less than 18%, ensuring excellent energy dissipation capacity.

Significant economic benefits

· Enhances stress management, is economical and environmentally friendly, and reduces total project cost.

Easy installation

· Convenient to install, inspect, and replace with low operation and maintenance costs.

Rectangular ultra-high damping isolation rubber bearing

Circular ultra-high damping isolation rubber bearing

High-performance seismic isolation bearings for buildings

· Developed high-performance composite rubber with seismic isolation bearings that exhibit stable conventional mechanical properties and an ultimate shear strain of up to 500%.

Circumferential Wire Rope Composite Damping Bearing

The circumferential wire rope composite damping bearing consists of a circumferential wire rope damper integrated with various types of bearings. It dissipates vibration energy through shear deformation of the bearing and changes in the wire rope ring configuration. The technical characteristics are as follows:

High damping ratio and circumferential seismic resistance

· Offers a substantial damping ratio with strong shock (vibration) suppression capabilities, a broad operating temperature range, and consistent mechanical properties within the circular plane, unaffected by the direction of unknown earthquakes.

Beam drop prevention function

· The circumferential wire rope damper features "rigidity hardening" under tension, effectively preventing beam falling without additional preventive devices.

Excellent economic benefits

· The three-in-one composite product (bearing + damper + beam falling prevention device) offers comprehensive functionality. It has a relatively compact size, reduces the section size of the superstructure, reduces prestress, and saves on investment.

Force Measuring and Adjusting Bearing

The force-measuring and force-adjusting bearing system comprises the bearing body, force measurement system, and force adjustment system. In addition to the conventional bearing functions, it integrates IoT technology through the force measurement and adjustment systems, forming a comprehensive solution for intelligent bridge health monitoring.
