The 'Unbonded Brace' is a highly experienced seismic and vibration control component. The core (central steel material) expands and contracts, softly absorbing the shaking from earthquakes. Its armor (steel pipe) and muscle (mortar) prevent the core (central steel material) from breaking, which is also a key feature. We offer both seismic and vibration control types, and both types provide significant advantages for 'seismic retrofitting' and 'civil engineering and bridge design.' [Features] ■ Mitigates large shakes through the 'expansion and contraction of the core' ■ Smart ■ Can reduce the amount of steel in buildings ■ Actively used in both new constructions and seismic retrofitting *For more details, please refer to the PDF materials or feel free to contact us.

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.

The "Unbonded Brace" is a hysteretic damper of the axial yielding type that can economically improve seismic performance by installing it as a damping material in structures such as brace-supported ramen bridges, applicable to both new and existing bridges. To efficiently absorb seismic energy, the seismic forces acting on various components are significantly reduced. This leads to a decrease in the amount of steel and reinforcement materials used, thereby enhancing cost-effectiveness. Furthermore, when used for seismic reinforcement of existing bridges, the number of sections requiring cross-sectional reinforcement is reduced, allowing for a shorter construction period compared to conventional seismic reinforcement work. 【Features】 ■ Economically improves seismic performance ■ Significantly reduces seismic response of each component ■ Enables shortening of construction period ■ Enhances maintenance management ■ Registered with NETIS [NETIS Registration Number: KK-100051-A] For more details, please refer to the catalog or feel free to contact us.
