linear natural rubber bearing (NRB)
a cost-efficient decoupling component focused solely on shifting the building's vibration period. Because it provides minimal damping, it is best suited for hybrid seismic designs where separate, specialized dampers are utilized to control sway.
Lead rubber bearing (lrb)
An integrated solution providing both structural support and high energy dissipation through a lead core. It is the industry-standard choice for balancing lateral displacement and damping in high-occupancy developments.
HIGH DAMPING RUBBER (HDR) BEARING
A streamlined, "all-in-one" isolator that uses engineered rubber compounds to dissipate energy without a metal core. It offers a cleaner architectural footprint and is ideal for projects requiring a predictable, low-maintenance seismic response.
FRICTION PENDULUM SLIDING (FPS) BEARING
A compact mechanical slider that uses a curved surface to trigger a pendulum-like motion during a quake. Its performance is mass-independent, making it a versatile choice for both large heavy structures and low-rise structures.
VISCOUS FLUID DAMPERS (VFD)
FLEXIBLE PIPES (Braided hose/ rubber pipes)
FLEXIBLE PIPES (Braided hose/ rubber pipes)
Absorbs and dissipates seismic energy through controlled fluid resistance. This reduces structural acceleration and drift without limiting building flexibility. Ideal for new construction and retrofit applications where supplementary damping is required.
FLEXIBLE PIPES (Braided hose/ rubber pipes)
FLEXIBLE PIPES (Braided hose/ rubber pipes)
FLEXIBLE PIPES (Braided hose/ rubber pipes)
Accommodates relative movement between isolated and fixed structures, ensuring piping systems remain intact and operational during and after an earthquake. A critical component for maintaining building services for water and fire suppression.
Seismic expansion Joint
FLEXIBLE PIPES (Braided hose/ rubber pipes)
Seismic expansion Joint
Bridges the isolation gap between a base-isolated structure and surrounding fixed elements, allowing large displacements without damage to finishes, facades, or flooring. Engineered to maintain architectural integrity while accommodating full seismic travel.
What is base isolation?
Types of Seismic Resistance
While traditional buidlings apply Seismic Resistance that relies on a rigid frame that intentionally bends and deforms to absorb earthquake energy, it often results in permanent structural cracks and severe internal swaying.
Vibration Control upgrades this approach by adding internal, energy-dissipative dampers that act like automotive shock absorbers to significantly reduce building distortion and manage sway.
In contrast, Base Isolation completely decouples the structure from the ground using specialized bearings, shifting all seismic movement to the foundation pit so the building itself experiences zero inter-story drift and maintains a completely safe interior environment.
Overview of Seismic Base Isolation Systems for Buildings
Seismic base isolation is an effective earthquake protection method that involves the use of rubber bearings. These base isolation systems allow buildings to move independently of ground motion, significantly enhancing their resilience during seismic events.
