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.
Visualization
Building A is a conventional fixed-base building taking on the absolute brunt of seismic energy.
Building B is equipped with advanced Lead Rubber Bearings (LRB).
Notice how the bearings handle the violent shift while the building itself glides smoothly. It makes sure everything and everyone inside stays perfectly safe and operational.
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.
PRODUCTS
LINEAR NATURAL RUBBER (LNR) BEARING
This highly durable and flexible base isolation system utilizes laminated natural rubber and steel plates, designed to effectively shift a building’s vibration period during an earthquake, providing essential earthquake protection through advanced rubber bearings.
LEAD RUBBER BEARING (LRB)
This heavy-duty base isolation system features a central lead core that deforms to dissipate energy, ensuring effective earthquake protection and providing stable damping during intense vibrations with the help of rubber bearings.
HIGH DAMPING RUBBER (HDR) BEARING
This specialized base isolation system utilizes high-viscosity rubber bearings to effectively support structural weight while simultaneously absorbing earthquake energy, eliminating the need for additional dampers for earthquake protection.
FRICTION PENDULUM SLIDING (FPS) BEARING
This high-performance base isolation system utilizes the principle of a pendulum and controlled friction, allowing structures equipped with rubber bearings to glide smoothly during an earthquake, naturally returning them to their original position for effective earthquake protection.
