Seismic Isolation Component for Construction 'NS-SSB'

To achieve the target performance, we pursue suitable materials and combinations for the sliding material and sliding plate.

The "NS-SSB" is a seismic isolation component for construction that utilizes the principle of a pendulum. The natural period of the seismic isolation layer depends on the precision of the radius of curvature of the concave plate's spherical surface. Since it is machined under computer control, manufacturing variation is minimal, and there is almost no variation due to aging. Furthermore, by using metal materials as the main component, it achieves a surface pressure approximately three times that of laminated rubber bearings. Due to the high surface pressure, the device itself is compact, and the joints with the upper structure and foundation are also compact. [Features] - The natural period of the seismic isolation layer is not affected by fixed loads or imposed loads. - A single seismic isolation component can achieve a longer period. - Performance variation is minimal. - The reference surface pressure is 60 N/mm². - Selection of seismic isolation components is easy. *For more details, please refer to the PDF document or feel free to contact us.
